This heater appliance is intended for use as a warm air curtain and is to be mounted on the wall
above doorways or along a wall. It is to be mounted with the underside a maximum of 2.1 metres
above floor level. It can be mounted directly to a wall surface to provide a near vertically
downward air discharge or on angled mounting brackets (supplied) to provide an air discharge
angled 25° from downward. If exceeding 3 metres there will be a reduction in performance.
THE STERLING “E” PC (PULL CORD MODEL) SHOULD BE USED IN
BATHROOMS OR SIMILAR HIGH HUMIDITY AREAS. DO NOT USE THE
STANDARD 2 kW & 4kW.
