3. MOUNTING INSTALLATION 
❑
 
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 
230mm 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 1148mm 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. 
4. ELECTRICAL CONNECTIONS 
230V SINGLE PHASE –Power Connection 
Please make sure you have read the Safety instructions and that you are a suitably qualified electrician 
before continuing. 
Drawings show connections inside the black terminal box on the outside of the heater. 
Do NOT use power tools to undo or do up terminal screws in the Power Supply Box. 
Please Note: - Specified cable sizes are for typical installations, correction factors may need to be used when 
determining actual cable sizes. 
 
Standard Connection 
 
Use 4mm² 3 Core Mains Cable (see note above). 
Connect Brown wire –Terminal 1 or L. 
Connect Blue wire –Terminal 5 or N. 
Connect Green / Yellow wire –Terminal E or 
 
PLEASE CHECK ALL CONNECTIONS BEFORE TURNING ON AS INCORRECT WIRING IS NOT 
COVERED 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. MAINTENANCE 
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. AUTO CUT OUT / FUSE REPLACEMENT 
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. 
This unit is fused and the fuse holder is located in the centre of the front grill. Should the fuse fail, replace with another 12.5A fuse. If this 
replacement fuse fails seek professional help.
