Series 90 Vertical Sliding Operation and MaintenanceOperationThe sashes can slide after releasing any locking catches and the spring balances will support the sash in any position. Avoid any fast movement or slamming action, particularly on larger units, since this could damage the balances and window stops. It is recommended that both hands are used when operating the window to ensure even pressure on the balances. If an espagnolette lock has been fitted to the interlock bars it should only be operated when the window is closed to avoid damage to the locking keeps.MaintenanceCleaning AccessThe sashes are attached to the spiral spring balances and are` not normally be removed for cleaning purposes. They contra slide and the rear glass surface can be accessed from above and below. A long handle cleaner may be needed for tall sashes.CleaningThe cleaning cycle will be dictated by local conditions and should consist of washing down the glass and aluminium with a non alkaline detergent in warm water using a soft cloth. For more stubborn marks on the aluminium 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 then wipe dry. Chips or scratches in a paint finish can be touched in using a matching non cellulose paint and care must be taken not to get this 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 complementary.Balance AdjustmentThe balances are purpose made to suit the weight of the sashes and are not adjustable.Balance ReplacementWhen a balance fails, the weight of the sash becomes unsupported. It should be lowered to the bottom of the frame and a warning sign attached. The balances are purpose made and a replacement may be ordered through Selectaglaze, allowing a 4-5 week delivery period. A Method Statement can be provided by Selectaglaze to allow the work to be carried out by a competent person.Re-glazingThe sashes can be detached from the balances and removed from the frame to allow re-glazing. A Method Statement must be obtained from Selectaglaze beforehand and the work should only be carried out by a competent person after completing a full risk assessment. |
