Series 50 Hinged Casement Operation and Maintenance
OperationNon-security modeThe window is fitted with concealed locking points on the opening stile. When the handle is turned to the horizontal position it releases the catches allowing the vent to ease forward. Where rosette or fireman’s axe handles have been specified, a suitable operating key is required. The vent is supported on a seating block and this will provide a small amount of resistance to opening. A sliding stay arm limits opening to approximately 90°. Avoid fast movement since this could damage the stay. The handle should not be turned when the window is in the open position since the locking catches could be damaged if an attempt is then made to close the window.Security modeThe handle must be unlocked and turned through 180° before easing the sash forwards. The handle becomes 'locked off' and can only be turned when the window is back in the closed position. When closing the sash it will be necessary to apply reasonable pressure on the compression seals to allow the locking bars to bypass each other.MaintenanceCleaningThe 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.LubricationThe handle gear is sealed with lubricant for assembly, but other moving parts such as hinges and the corner drives for the security locking bars should receive occasional lubrication with a silicone spray.Vent removalIf the vent has to be detached from the frame for any reason, a manual handling assessment must first take place. Open the window and detach the stay arm in the non-security mode. Whilst supporting the vent remove the vent hinge screws and carefully lift it off its hinges. On no account should the frame hinge screws be removed since it would be extremely difficult to re-centre the vent upon re-fixingRe-glazingThe glass is bonded to the aluminium and the glazing pocket is formed from a two part bead. Should the glass be broken refer to Selectaglaze for advice on re-glazing. |
