INSTRUCTIONS FOR OPERATION

HORIZONTAL SLIDING SASHES
The sashes can be slid after releasing any locking catches fitted and they can be removed by lifting into the head of the frame. Avoid damage to rollers through standing on gritty surfaces and take care to re-instate sashes in the right sequence.

BALANCED VERTICAL SLIDING UNITS
The sliding sashes are attached to spiral spring balances and so cannot be removed. The ability to contra-slide the sashes helps when cleaning the glass surfaces. Always apply gentle pressure when opening or closing the sashes. Damage can occur if the sashes are moved too rapidly.

TILT-IN BALANCED VERTICAL SLIDERS
To operate sliding panels, undo the fitch catch to the centre of the meeting styles, which enables the bottom panel to slide up, and the top panel to slide down. In order to lock the catch again the top panel must be pushed right to the top and the bottom panel, right to the bottom and re-fasten the fitch catch.

To operate the tilt in facility, Disengage the fitch catch to the centre of the meeting styles, using the silver knobs located to the left and right hand side of the bottom panel pull the release catches towards the outer frame and tilt panel towards you.

In order to do the same procedure with the top panel the bottom panel has to be in the tilt in position.

Slide the top panel down as far as required and then use finger release catches to tilt towards you.

In order to return the top panel into a closed position, tilt the panel back towards the window and ensure the catches are locked into the track securely and slide as normal into the original position. Repeat this procedure with the bottom panel. When both panels have returned to their original positions the fitch catch can be locked.

VERTICAL SLIDERS
The sashes can be lifted or lowered vertically but the operator must be able to handle the weight of the sash.

Release the catches on each side of the sash and lower or raise the sash to pre-set positions. Carefully release the catches once in position. Reverse the sequence to replace the sashes in their original positions.

Damage can occur if the sashes are dropped when lowering.

The sashes can be removed for cleaning by removing the retaining clips on either the left or right hand side, sliding the panels sideways into the frame. The panels are then re-instated by reversing the process. Care must be taken to install the retaining clips the correct way.

LIFT OUT UNITS
The sashes can be removed by lifting vertically within the frame until the bottom edge is clear of the frame and can swing towards the operator. It is re-instated by reversing the process.

If the lift out has the inclusion of turnbuckles, the lift out panel is obviously held in place by the turnbuckles. These operate by rotating the buckle manually clear of the panel, approximately 180 and removing the panel as above. When the panel has been replace the buckles are moved back to their original positions.

Where units are over 1200mm by 1200mm; two persons are required to enable safe removal; and replacement.

SINGLE AND DOUBLE SIDE HUNG CASEMENTS
The operating handle is turned to the horizontal position to allow the windows to open. The "slave" sash of the double casements has a retention bolt fitted at cill level. This must be re-engaged when closing the window to ensure a good seal.

MAINTENANCE

There are no special maintenance requirements other than the periodic cleaning as all moving parts are factory sealed with lubricant before assembly. The cleaning cycle will be dictated by local conditions ans should consist of washing down the glass and aluminium with non-alkaline detergent in warm water using a soft cloth or sponge. For more stubborn marks a soft brush or nylon pad should be used. Avoid abrasive cleaners, steel wool, strong acids or alkalis. After cleaning it is advisable to rinse the surfaces with clean water and wipe dry.

Chips or scratches in the paint finish can be touched in using a non-cellulose paint but care must be taken to prevent paint getting into draught seals or moving parts. Repair of anodised finishes is not practical other than by touching in with a colour-matched paint but the finished appearance is seldom complimentary.

Bottom tracks of Horizontal Sliding Systems should occasionally be vacuumed to avoid dirt build-up and, if necessary, a silicone lubricant can be sprayed onto the track.
