Simple adjustment of plastic windows for winter, lubrication. Adjusting windows for the winter with your own hands Plastic windows switching to winter mode diagram

The design of plastic windows assumes the ability to adjust the degree of pressing of the window sash; this function is intended to transfer the system to seasonal winter-summer modes.

Plastic windows are installed in almost every third apartment or private house, but not all users are aware of the operational capabilities that metal-plastic windows provide.

One of the functional features is the transfer of the plastic window mode from winter to summer mode, and vice versa. This ability is determined by the type of fittings used. Of course, this property is not inherent to all PVC windows, but only to those on which more modern fittings are installed.

Modes of plastic windows - what are they and what is it?

Winter mode of plastic windows- this mode allows for a tighter fit of the window sash frame to the window frame and, accordingly, helps save heat in the winter;
Summer mode of plastic windows- characterized by a less tight fit of the sash, which ensures constant air circulation between the room and the environment, i.e. allows you to implement micro-ventilation mode.
Standard position(the mode of average pressing of the sash to the frame - the eccentric is in the middle), as a rule, a window with a double-glazed window in this mode works equally well in both winter and summer, providing optimal pressing of the seal.

Why do you need to adjust the modes of plastic windows?

Setting the modes makes it possible to extend the service life of the window. The adjustment allows you to change the degree of fit of the sash to the frame. After all, in winter the material contracts, and in summer it expands. Adjusting the PVC window fittings makes it possible to reduce wear on the seal and fasteners.

In addition, reasons to change modes include:

blows from the window. Cold air in winter or dust in summer is what one strives to avoid when installing a new window;

The door opens/closes poorly. For example, if a plastic window is jammed in the ventilation mode, then one of the reasons may be an incorrectly set mode;

sagging window sash. It is a consequence of wear on the hinges and can be eliminated by switching to winter mode or replacing fittings.

The ability to switch between modes is implemented in fittings from well-known manufacturers, such as: Maco, Roto, Siegenia Aubi, GU. However, today, setting up fittings is the rule rather than the exception for all fittings of a class higher than the budget one.

How to determine whether it is possible to switch the windows to winter mode?

Often during installation, the user does not receive information about the capabilities of window fittings. To understand whether transfer to different modes is provided for a particular PVC window, you need to study the appearance (labeling) of the fittings, in particular the trunnion.

A trunnion or eccentric is an element of fittings that allows you to adjust the degree of pressure of the sash to the window frame. It is located on the side of the sash.

If the surface of the trunnion has holes for a key (in the form of an asterisk, screwdriver, hexagon) or the trunnion has an oval shape, this indicates that this hardware allows the window to be used in different seasonal modes.

Do I need to switch the windows to winter mode?

In autumn, with the approach of cold weather, it is recommended to switch the fittings to winter mode. Otherwise, there is a high probability of blowing from the side of the sash. If the seal is in good condition, you can leave the window on summer mode. During the warming period, switching the fittings to summer mode helps reduce the pressure (load) on the seal and is a prerequisite for its long-term operation.

How to determine what mode plastic windows are in?

There are two ways to check what mode the window is running in:

Assess the degree of pressing of the window sash to the frame. Take a sheet of paper and place it between the sash and the frame. If, after closing the window, the clamped sheet is pulled out with minimal force, then the window is set to summer mode; if it does not pull out (breaks), then it’s set to winter mode.

Look at the position of the trunnion (eccentric). There is a dash (dot, asterisk) on the round pin by which you can evaluate the mode. If the line is oriented towards the room, this is winter mode, if towards the street - summer mode.

For oval trunnions, a different rule applies. If it is located vertically, the sash is weakly pressed against the window frame, which allows us to say that the window is set to summer mode. If horizontal - strong pressure, i.e. winter mode.

How to switch plastic windows to winter mode or summer mode

Transferring between modes is simple, but each step must be given attention, otherwise the fittings will fail and will require replacement or major window repairs. Some users prefer to seek services from the company that installed the windows.

However, the translation process is not complicated and it is quite possible to complete it yourself, spending no more than half an hour on everything.

How to adjust plastic windows for winter mode with your own hands

Adjusting trunnions on plastic windows - step-by-step instructions:

determine the location of the trunnions. The number of eccentrics depends on the size of the sash. As a rule, there are three of them on the handle side and one on the opposite side (where the hinges, awnings, and also on the top and bottom of the sash). You need to find all the trunnions, because... when changing modes, you need to change the position of each of them;
wipe all window elements and thoroughly clean the fittings. This will prevent dust from entering when turning the trunnions and protect them from mechanical damage;
clean lubricated elements. After the transition, it is better to reapply the lubricant;
consider the trunnions. Find stripes or other markings on their surface indicating the operating mode of the window. If the trunnions are oval, pay attention to their position relative to the horizontal;
Rotate each of the trunnions to the required position. You need to turn it either using a hexagon (or other suitable tool) or pliers (for oval journals).
check the accuracy of the translation by placing and then removing a sheet of paper from a closed window.

Note. Some manufacturers of plastic windows make the trunnions “recessed” into the sash. Before turning them, you need to pull them out, then set them in the desired position and push them in again. The turning procedure is similar to the procedure for moving the hands on a mechanical wristwatch.

Please note - when switching to winter mode, the long line (or dot) should be directed towards the room (i.e. towards the sealing rubber), and in the case of an oval trunnion it is located horizontally.

How to switch plastic windows to winter mode - video

For your information, the winter ventilation mode for plastic windows works as standard and the window opens in the usual way.

The transition to summer mode is carried out similarly, in reverse order. Knowing the sequence of transition to winter mode, it is easy to set the window fittings to summer mode.

Features of setting up window fittings - rules

Despite the fact that the fittings provide the possibility of switching between modes, it is not recommended to do this in the first year of operation of the window. The window is still functioning optimally;

translation is carried out once every six months. Moreover, the duration of the winter period is shorter than the summer period;

It is undesirable to operate the window in winter mode in summer, as this increases the rate of wear of the seal.

Is it worth switching plastic windows to winter mode?

Constant change of modes leads to the fact that the seal loses its properties. This happens especially quickly in winter mode, because... the pressure of the trunnion on it increases. In addition to the impact of the trunnion, the seal is affected by low temperature and high humidity. This leads to destruction of the seal (it starts to blow, there is a need for), the worn rubber seal requires replacement. In summer mode, the seal will last at least twice as long.

Conclusion

Despite the possibilities that modern window fittings provide, you need to evaluate the feasibility of each option. On the one hand, switching to winter/summer mode provides a more comfortable temperature in the room and reduces heat loss through the window opening. On the other hand, translation contributes to rapid wear of the seal, which necessitates its replacement and additional costs. Therefore, whether to switch windows for winter or not is up to each user based on his personal preferences.

Having installed “winter-summer” or “winter-summer-autumn” systems with seasonal adjustment of fittings has great advantages: in winter, waterproofing and thermal protection are maintained through the sealing of window parts, and in summer there is sufficient protection from dust and heat.

Unfortunately, not every plastic window provides the ability to change settings; this does not depend on the quality of the double-glazed window, but on the class of the installed fittings.

It is customary to distinguish three main types:

Budget fittings. Provides basic functions - opening and closing window sashes without additional resources. It belongs to the low price segment and is often installed in new buildings.
Standard fittings. There are adjustment systems, good quality characteristics. Average price category.
Specialized fittings. Developments with elements of anti-burglary fortifications. Seasonal changes in settings “summer-autumn-winter” are provided.

What are they and why are they needed?

Switching the window to winter and summer mode

The concept of operating mode is associated with the degree of pressing of window fittings to the base and, accordingly, of the sashes to the frame seals. In winter mode, the setting maximizes the tightness of the structure. Thus, isolation from the external environment is enhanced.

At the end of the winter period, it is time to reconfigure winter settings to summer ones in order to prevent wear of the fittings fastening parts and abrasion of the seal.

By default, when purchasing or installing windows, summer mode is always set to extend the shelf life of the internal seal. Unfortunately, when installing double-glazed windows, consumers are very rarely instructed on the functioning and operation of seasonal settings.

Summer and winter modes, as the main ones, protect the interior from drafts, guarantee comfort and tightness of plastic windows depending on the season. If such a technical possibility exists, it is recommended to carry out periodic adjustments.

Adjustment is available to any consumer; no need to call specialists. The only recommendation when changing the settings is to be careful not to damage the fittings and extend the life of the glass unit.

How can I check if a window can be translated?

If, during installation or moving into an apartment, it remains unclear whether the double-glazed window has season settings, then you can find out for yourself. First, open the doors and look at the fastenings. On the side there are special eccentrics, or otherwise trunnions.

This is the name given to a small mechanism that serves to hold the sash when it is closed. When closing the window, you can hear a characteristic click - this is the sound of a working pin. Thanks to this device, adjustments are made to the changing seasons.

The eccentrics must have holes for a hex key, a star screwdriver or a regular screwdriver. Their presence is a kind of confirmation of the ability to adjust the seasonal settings of the seal.

The oval shape of the eccentric also speaks of this. There may be several or one trunnion, depending on the size of the valves and the manufacturer. With their help you can change the mode.

If these holes are missing, you will not be able to change the seasonal settings. The solution to the problem may be to replace the fittings or sealing elements to ensure the sealing of the structure in winter.

How to change the mode yourself?

Trunnion adjustment diagram

Changing the seasonal regime on double-glazed windows is not a difficult task. But before you get started, decide whether this is necessary. Double-glazed windows are inherently reliable protection from the external environment. In mild, not too cold weather, it is not worth resetting the mode, so as not to expose the seal to additional wear.

Step by step guide:

Step 1. Preparatory. Open the sashes and use a damp cloth to clean the joints and connections on the end side of the sashes. It is important to prevent dirt from getting into the internal mechanisms and hinges. Use a hard brush to clean the fittings and remove traces of dried grease. If necessary, replace the worn seal and re-lubricate the adjustment screws and hinges with machine or vegetable oil. There is a special tool for processing accessories available for sale in a syringe tube, convenient for use.
Step 2. To avoid distortion or sagging of the sash, it is recommended to check the geometry of the window position. To do this, the closed sash is lightly outlined around the perimeter with a pencil. Then, the sash needs to be opened and the distance from the drawn lines to the frame opening measured. Ideally, it should be the same or have a small error of up to 5 mm. If there are deviations in the upper part, then you should remove the decorative inserts from the hinges and tighten the screws at the bottom with a hexagon. If there are deviations in the lower part of the contour, adjustments are made at the top. The load on the hinges must be uniform.
Step 3. Count all the eccentrics, or trunnions. Their number may vary depending on the size of the window. Everything must be transferred to another mode.
Step 4. Using pliers, a hex key or a screwdriver, you need to turn each eccentric clockwise so as to press the seal as much as possible. Some types of fittings provide for the initial pull of the pin towards itself before turning it, similar to the winding mechanism of a watch.
Step 5. The result of changing the mode can be seen using a simple sheet of paper. Place the sheet so that it is sandwiched between the sash and frame and close the window. Try to pull out the paper. If you succeeded without difficulty, then the established summer mode has been preserved. If the paper is pressed tightly and tears in an attempt to pull it out, it means that the setting has been changed; the window is sealed in the winter format. Please note that turning the window handle has also become more difficult.

When is it time to transfer?

You can replace seasonal modes and adjust fittings along the way if the following reasons exist:

Window sashes are blown around the perimeter in cold autumn, heat leaves, cold air and dust enter the cracks. The fittings are operating in summer mode or you do not know their condition.
Spring-summer period. It's time to free the windows from additional load to protect the seals and other parts from wear.
Difficulty opening the doors, which may be due to winter conditions or sagging hinges.
Presence of sagging sashes or offsets relative to the window. Perhaps the reason is a worn seal or incorrect setting of the seasonal mode.

It should be noted that reconfiguring modes for no reason is not recommended, especially for new windows. On average, fittings can be adjusted no more than once every six months.

Changing the “winter-summer” regime at plastic windows is carried out mainly by residents independently.

Refer to instructions, if they are preserved, to study the features of the supplied double-glazed windows.
Consult with specialists from window installation companies or experienced users of double-glazed windows.
Correctly assess the technical condition of windows to carry out the adjustment: you can break the adjustment bolts or cause the seal to become deformed. As a result, a complete replacement of the fittings and seal will be required.

In general, the right solution will allow you to create maximum comfort indoors at any time of the year, and your plastic windows will last for decades.

Plastic (even high quality) windows with a high level of thermal protection and high-quality waterproofing in winter are susceptible to both sweating and freezing. This is not at all a sign of defective or incorrect installation. Most likely, you simply did not take care of the proper seasonal preparation of your own windows.

Today we will talk about this topical topic. So, how to switch plastic windows to winter mode, get rid of drafts and achieve additional insulation of frames? To answer this question, let’s take a closer look at all the “weak points”.

Winter mode of plastic windows and fittings

About her - first of all. Basically, modern windows are equipped with fittings designed for 2 or 3 seasonal modes. This is either “summer-winter” or “summer-winter-autumn”. Some window owners are not even aware of this and when it gets colder they begin to curse the “hack-working” manufacturers. But we will correct this misunderstanding - we will talk about how to switch plastic windows to winter mode. The photos posted in the article will help the reader in terms of clarity.

Most often the situation is fixable: it all comes down to turning a couple of bolts. We switch our windows to “winter” and forget about the problems. To do this, pay attention to the pivot pin. What it is? A pin is a miniature mechanism with which the sashes can be held in the slammed position, most often its location is along the perimeter of the window. Remember the click when the sash slams shut? It was the trunnion that worked.

How to find her?

It may look like a ring or an oval lever. If this ring is in the form of a nut, there is a hole mark on it. Check: when it is located close to the frame with the seal, this is winter mode. This ensures the greatest possible fit of the sash to the profile. Why shouldn't you use it all year round? Yes, simply because the seal will quickly wear out and go into circulation.

The trunnion (given its oval shape) is adjusted very easily, without any tools. In the form of a nut - using a hexagon. By turning the ring with it, we achieve the movement of the small circle-mark closer to the seal. Going back to “summer” is as easy as switching plastic windows to winter mode - by turning the ring.

On the eve of cold weather, handles and hinges need to be lubricated with machine or vegetable oil or a special product from a syringe tube.

Let's take care of the seal

We are talking about a rubber gasket between the sash and the frame. It is also considered a sealant for the edges of glass units. At the end of autumn, feel it around the perimeter and make sure it is elastic, especially in the corners. Normally, it bends easily and quickly takes its original shape.

If this is not the case, it is impossible to revive it by any means; you will have to change it. If everything is in order, then before you switch the plastic windows to winter mode, take care of its preparation by purchasing it in an aerosol or tube with a syringe.

The lubricant is applied with a brush to a well-washed and dried seal (it is better to use dish gel, but not alcohol or abrasives). If the sealant is multi-petal, first place the product between the petals.

Don't forget about the sealant around the edges of the glass unit. If there is no bead in this part of the window (not provided for by the design or simply broken), the glazing seal is lubricated in the same way as usual.

What to do with seams?

We are talking about the seams between the profile and the window opening. This is where the main heat from the room “leaks away”. Before switching plastic windows to winter mode, make sure there are no drafts. In addition to the latter, condensation and even ice on the window will indicate damaged thermal insulation. An additional layer of polyurethane foam will help get rid of these problems. Even more reliable are plastic plates or drywall in combination with mineral wool.

It is not recommended to insulate plastic windows using “folk” methods - cotton wool, homemade putties, etc. Most of these products are not only ineffective, but can also cause harm - fabric and cotton wool retain moisture inside, which leads to fungus and condensation, and covering the crack with wax or melted paraffin, you risk damaging the factory seal.

How to switch plastic windows to winter mode (roto)

We are talking about a popular product widely known to the consumer market in various modifications and supplied by various manufacturers in many countries. The principles of its adjustment are the same for any model.

How to switch plastic windows to winter mode if you have such fittings? Modern models are adjusted with a 4mm hex key, older models with pliers and a screwdriver. What are the main problems that require our intervention?

If, when closing the window sash, we touch the frame below, it is sagging. A slight lift is required: remove the protective cap from the bottom hinge (at the top), using a hexagon inserted into the recess, lift (rotating clockwise) or lower (counterclockwise) the frame a couple of millimeters. Usually this is enough.

When the sash “collides” with the frame in the middle part, you need to adjust it in the horizontal direction. This is done with special screws on the upper and lower hinges. If you rotate them clockwise, the sash will come closer to the hinge (the interference will decrease), and counterclockwise, it will move closer to the frame. The displacement is possible no more than 2-3 mm. We deal with distortion in the same way.

Don't forget about caring for your fittings

In order for the mechanism to serve for a long time and efficiently, the fittings need lubrication. To do this, take silicone or automotive lubricant WD-40 and apply it to the points of contact. This should be done at least once a year, before switching plastic windows to winter mode, and preferably twice as often.

Other, more complex problems require calling a service technician.

Nowadays it is difficult to imagine a modern apartment without plastic double-glazed windows on the windows.

Indeed, plastic windows are very popular today, as they have many advantages.

One of them is their ability to change mode from winter to summer. Of course, not all windows have this mode, but not the cheapest window models have this function.

Due to the fact that winter temperatures in our region differ significantly from summer temperatures, the requirements for windows are also different.

In winter mode, the seal is pressed as much as possible, and in summer mode, on the contrary, good ventilation occurs due to the precise distribution of the load between all the locks.

To find out if your window has this feature, you need to inspect it. If on the side of the sash there is a hole on the trunnion (lever) for an hex key or an asterisk next to the eccentrics, then your windows have the function of switching to summer and winter modes.

When to switch windows to winter mode

If in summer a slight blowing around the perimeter of the window is completely unnoticeable and does not in any way affect the temperature inside the room, then in winter, even a slight blowing due to a loose seal becomes noticeable.

If the temperature in your apartment has dropped significantly with the onset of cold autumn weather (this is especially true for the off-season period, when the heating in the houses has not yet been turned on) and, when you approach the window, you feel the air blowing, and the window sill is quite cold, then it’s time to change the mode operation of your window for the winter.

Transferring plastic windows to winter mode: instructions

How to switch windows to the desired mode?

First, wipe all window elements with a rag, and clean the fittings from dirt with a brush.
Some parts are oiled. It is best to remove the old grease and re-treat the mechanisms with silicone grease.
After this, it is necessary to adjust the position of the valves.
Then you need to find all the pins on the sash (the larger the window size, the more there are). They are usually 5-8 mm in size. All trunnions must be switched to the required mode, otherwise the seal will be pressed unevenly.
Consider the axle. Usually they have risks indicating winter and summer periods of work.
Next, using a hexagon or a screwdriver with pliers, you need to turn each lever to the maximum position. Sometimes it is necessary to first pull the trunnion towards you, and only then turn it clockwise. Then it is necessary to return the trunnion to its previous position, that is, to drown it. You perform a similar action when changing your wristwatch.
At the end, you need to check how correctly you did everything. In winter mode, the handle will close much tighter due to the seal being attached more tightly. You can insert a sheet of paper into the sash and close the window, and then try to pull the sheet out. In winter mode, it should not be easily removed, and with a high-quality seal, the sheet should be securely fixed. If this is the case, then you did everything correctly, and now there will be no air blowing from the windows.

In principle, this is not so difficult, but it should be taken into account that if something is done carelessly, there is a risk of damaging the structure. Therefore, if you are not confident in your own abilities, it would be better to turn to professionals for help in translating windows.

Note! If the apartment is warm without switching the windows to winter mode, then there is no need to do this, since the wear of the seal in this mode is much greater.

Finally

Based on all of the above, we can conclude: if you notice any changes in the functionality of your plastic window, for example, if it starts to blow from the window or the window freezes and condensation occurs, or the sash begins to cling when torn off, then you need to change your window mode. As mentioned above, this is quite easy to do.

PVC windows have many advantages compared to conventional windows or other types of double-glazed windows. Take, for example, one of the most significant advantages is the setting of winter or summer mode. Not all plastic structures provide such modes, but many do.

The functionality of a window depends on the fittings it has. It may be functionally limited, or it may have many useful functions.

Hardware classes

Depending on the class of fittings, the ability of a PVC structure to transition or not to transition from one mode to another is determined - from winter to summer and vice versa. The quality and functions of the fittings depend on the class. The manufacturer is also important, but not so much.

The following classes (or types) are distinguished:

Budget. Fittings of this class are installed in windows with the lowest price. Allows you to only open and close windows.
Standard. The fittings are provided for medium-priced PVC structures. Allows you to prepare windows for winter or summer.
Specialized. Such fittings can be combined with anti-burglary fittings. Allows you to configure the window to the required mode.

What are modes for?

Modes are needed for one simple reason - the weather outside is constantly changing. Winter is replaced by summer and vice versa. Accordingly, there is a constant drop or rise in temperature. Thanks to the ability to close the window more tightly or, conversely, less tightly, it becomes possible to adjust the “climate” of the room.

Summer mode

In the summer, the main functions of the PVC structure are to minimize heat, dust, dirt, and so on. This is why the summer system was invented. It allows you to adjust the pressing density of the sashes to maximum loosening, which is very important to do after a long winter. To do this, the nut is unscrewed counterclockwise, and the effect of the eccentric on the frame is thereby weakened.

Winter mode

During the winter period, you want to keep as much heat indoors as possible. To do this, the position of the eccentrics changes in the direction of “sealing” the PVC structure. By moving, they allow the sashes to be fixed more tightly to the frame insulation. By the way, during operation the insulation can wear out greatly, so it is important to make transfers of modes on time.

Transferring from one system to another can be done independently, but everything must be done carefully and slowly. An error in action may result in damage to the plastic structure. To avoid this, you can invite a specialist from the company or store where the PVC was purchased.

Blowing out of a plastic window can be caused by:

Poor compression of glass with glazing bead. This is especially true in winter, since materials tend to shrink when exposed to cold. Accordingly, the glazing bead can fly out of the grooves, and the glass, in turn, can fly out of the glazing bead. It should be replaced if necessary, but it is best to entrust this work to professionals.
Incorrect selection of fittings for the structure. If the rubberized seal is of uneven thickness or is pressed unevenly by mechanisms, then gaps may appear to allow cold air to pass through.
Poor quality material from which the profile is made. It may simply crack over time.
Incorrect installation of the frame. As a result, the doors may not function well and may not close properly.
By passing air at the junction of the frame and the vertical profile element. The gap should be sealed with liquid plastic, which comes with the PVC.

Change modes or not

There are a number of reasons why the regime must be changed:

The doors begin to close when opened, or no longer open at all. This may be due to sagging of the sashes, which in turn are attached to the frame using hinges. It is also possible that the winter mode was set incorrectly using the adjusting screw.
The seal may wear out. In this case, dust and wind will freely penetrate into the room. If it is warm outside, then you should immediately replace the insulation gasket.
The sashes can also be shifted in the horizontal plane. This directly indicates that the setup was initially performed incorrectly.

One of the reasons was about the seal. So, in order to avoid its wear and tear, it is not always necessary to adjust the PVC structure specifically for the winter. When pressed tightly, the seal wears out greatly. Therefore, winter mode is necessary, but if possible, its use should be limited. It all depends on the weather; if the winter is windy with snowstorms and blizzards, then cold and frost will penetrate the house.

How to find out if a window can be set to winter mode

In order to find out the functionality of the PVC structure, it is necessary to examine it from the inner end. There should be a hole for a screwdriver in the handle area. If there is one, then the plastic window can be converted from one structure to another. But you also need to know that the hole must be suitable for a hexagon.

If it is oval-shaped, then there can be two options: either PVC is converted into summer and winter modes, or not. You need to check with the seller.

How to switch a window to winter mode and back

The transfer is carried out by performing the following steps:

To begin with, the inner end of the sash is inspected to find eccentrics. Their number may vary, but each one needs to be configured separately.
The eccentrics are moved primarily clockwise until the sash is tightly pressed against the seal. Here you need tools such as a wrench or pliers.
All that remains is to check whether all actions have been performed correctly. Here you will need a regular sheet of paper. It is clamped with a PVC sash. If after this procedure, the sheet is easily removed from the gap between the sash and the frame, then the window still has a summer frame. If the sheet cannot be removed, the PVC is installed with a winter orientation in mind.

Thus, summer tuning is performed in reverse chronological order.

Step-by-step instruction

In general, the entire translation process is as follows:

Initially, the inner end surface of the valves is thoroughly cleaned. Particular attention should be paid to joints and connections. The end of the frame also needs to be cleaned. This is done to ensure that no dirt gets on the mechanisms or fittings of the doors.
The fittings themselves are additionally cleaned with a hard bristle brush.
Seals and surfaces that come into contact with them are wiped with a rag. This is necessary to remove old grease and dirt accumulated on it.
Seals can be replaced if necessary if they are worn out, for example, due to long or improper use.
Upon completion of the preliminary work, the eccentrics and hinges are lubricated with silicone.
Next, the trunnions are adjusted with a hexagon or screwdriver. They are turned in a certain direction, adjusting the pressure of the valves. Some types of eccentrics must first be pulled a certain distance from the end of the sash. They are turned by the protrusions and then returned to their original position.
The adjustment is now checked. If the trunnions are adjusted to winter mode, then when you turn the handle, it will function poorly. If the summer mode is set, the handle will turn easily.

Removing a worn seal:

The old rubberized gasket is removed from the frame grooves.
The profile must be wiped with a cloth, thereby removing dirt and dust.
The corners of the frame are filled with special glue for rubber.
The grooves are laid with new insulation. This is done carefully, without tension.
All excess is cut off, and the joints of the seal are glued together.

Incorrect setting

First, a little about the correct setup:

A correctly adjusted window does not create any sounds during operation, for example, the sounds of rubbing parts or surfaces.
The parts responsible for the correct position of the sash in space should be located approximately the same.
The rubber gaskets between the sash and the frame must be elastic and easily return to their original shape after opening the sash.

The setup can be done independently, since no special knowledge or skills are needed. But it is still necessary to carry out all work carefully. Even with small adjustment errors, the window may break, therefore, urgent repairs will be required.

What needs to be done before starting adjustment work, and what can result from non-compliance with the rules:

You should find and use the instructions included with the PVC. If you randomly change the positions of the eccentrics, they may become unsuitable for further use and the entire adjustment mechanism may be disrupted. The pressure rollers and rubberized seal may also be damaged.
It is worth checking the technical condition of the window first. If some parts are very worn, for example, a seal, then it will not be possible to adjust the winter mode. But you will be able to break the bolts.

Thus, seasonal modes have many advantages. They allow you to adjust the “climate” indoors, at home. Winter adjustment is especially important, since constant drafts can cause a lot of trouble.

Transferring modes should not be done more often than once every six months. More frequent changes may cause wear of some parts of the PVC structure or even breakage. To ensure that breakdowns occur as rarely as possible or not at all, it is worth taking care of the PVC structure. It must be cleaned and lubricated on time. The instructions contain detailed descriptions of care, the main thing is to follow them.
