IMPORTANT!
Ensure that the mounting surface / ceiling supports are capable
of taking the additional weight of the heater.
❑
IMPORTANT!
Before cutting out the hole to take the heater ensure there is
200mm clearance behind and that there are no cables or pipes in the way.
The heater is intended for installation in ceilings, walls or bulkheads. When wall
mounted the heater MUST be positioned horizontally. For optimum results do not fit
in ceilings lower than 1.8m or higher than 3m. As air is only introduced through the
front of the unit the heater may be sited anywhere. The air intake and discharge
areas must be kept completely clear for a minimum of 1.5m from the front of the
heater. In an area using multiple units, heaters should be spread to provide an even
heat distribution.
Cut a rectangular hole 315mm long x 150mm wide (See drawing to the right).
The heater should be held in position using suitable fixtures using the pre-punched
slots / holes in the face of the unit.

BY THE GUARANTEE
Once the mains cable has been connected the heater will
not work until a suitable controller is attached
to the
heater using a CAT5 network cable. We recommend you use our cables as they have been tested for
compatibility between all the controllers and the various different heater models. Instructions on connecting
controllers is found within the controller packaging.
5 . M A I N T E N A N C E
Note:
Before examining or carrying out any maintenance ensure the heater has cooled down and is disconnected from the mains supply.
The heaters are intended to operate for many years, problem free. All moving parts are factory lubricated and therefore should require no service.
Maintenance is limited to keeping both the inlet and outlet areas free from any accumulation of dust or any other foreign materials. This is especially
important immediately before the heating season. Any dust build up can be loosened using a brush and a vacuum cleaner applied to the airways to
ensure completed removal of any dust. When the heater is first turned on after cleaning an unusual odour may be noted this is due to the dust
particles which inevitably will be disturbed and will be burnt off from the heating element.
If in any doubt always consult a qualified electrician for advice.
6 . A U T O C U T O U T
This heater is fitted with a semi-automatic safety device to prevent overheating. The device will isolate the heating element while the fan continues
to operate. Should this occur, disconnect the heater from the mains supply for a minimum of 5 minutes, check and remove any foreign materials
around the airways. If the heater fails to operate or the safety cut out operates again, turn off the heater and contact a qualified electrician.
