Fitting Instructions for PVCu Windows & Doors – Adjustments

Window hinges

Generally the window hinges require no adjustment. However should you wish to adjust the tension on the friction stay, this can be achieved by screwing the brass screw, set in the black plastic pad, in or out to increase or decrease the tension. The adjustment screw can be accessed by opening the vent.

Window locking mushroom cams

The cams on the window locking mechanism can be adjusted with an Allen key that is located in the centre of the mushroom cams. The cams are eccentric and can be turned to increase or decrease the closing pressure of the mechanism. They should also be used to adjust the cams if you experience any ‘wracking’ of the window vent. This is usually caused by the pressure being too tight and the cams grinding onto the keeps.

Door Hinges

Door hinges can be adjusted in three planes. Vertically, horizontally and in/out.

Vertical adjustment can be achieved by a 4mm AF Allen key via the hole on the side of the diecast cover. Horizontal adjustment is by a 5mm AF Allen key in the the base of the hinge pin which can be accessed by removal of the plastic base cover. In/out adjustment, although rarely necessary, is similarly adjusted by turning the eccentric top screw found under the top plastic cover.

Door locking mushroom cams

The cams on the door locking mechanism can be adjusted with an Allen key that is located in the centre of the mushroom cams. The cams are eccentric and can be turned to increase or decrease the closing pressure of the mechanism. They should also be used to adjust the cams if you experience any ‘wracking’ of the door vent.

On no account should mechanisms or hinges be adjusted to compensate for incorrect installation or ‘toe & heeling’ of the glass. Adjustments should only be carried out after you are certain that the installation has been carried out correctly. Should you request a service call and any of these instructions have not been applied, a charge will be made.

Provided that you have observed the instructions in this leaflet, your windows and doors will provide you with years of trouble free service with only the occasional oiling of moving parts being necessary.

Completion

All that remains is the cleaning of the frames and then sealing them. The frames should be cleaned with clean soapy water, a non abrasive cleaning cream may be used for stubborn marks.

After the frames and working area has been cleaned the frames should be sealed inside and out with a silicone sealant, alternatively a painters caulk may be used inside only.

Using a thin opening of the nozzle, apply a thin continuous seal by squeezing the skeleton gun trigger with an even pressure. At the end of the stroke, press the release mechanism to stop the pressure. Keep the nozzle clean. Do the same outside but you may need to widen the nozzle by cutting it back, make a clean sloping cut with a sharp knife for easier application. You can also use masking tape for neatness, removing before the sealant sets. The sealant can be smoothed out by using a finger dipped in soapy water.
