Setup, Compatibility & Care
Installation should be performed by a qualified technician to ensure the door closer meets local safety regulations, especially for fire-rated doors. Ensure the door width does not exceed 950 mm prior to mounting. The unit is low maintenance; however, it is recommended to inspect the adjustment valves annually to ensure they have not shifted due to building settling. Clean the external casing with a soft, dry cloth; avoid harsh chemical cleaners that may damage the silver finish.
