3. MOUNTING INSTALLATION
3.1
CEILING MOUNTING
The heater is intended for installation in a suspended ceiling mounted within or on the 'tee' bar supports. For optimum results do not fit in ceilings higher than 3m. As air is
only introduced through the front of the unit the heater may be sighted 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.
IMPORTANT!
A minimum clearance of 205mm is needed between the bottom of the false ceiling and the original roof/ceiling to allow installation of the heater.
IMPORTANT!
DO NOT use plastic type diffusers as these may be damaged by the heat.
IMPORTANT!
Ensure that the mounting surface / ceiling supports are capable of taking the additional weight of the heater there are 2 eye hooks supplied with the
heater that should be used if additional support of the heater is required.
When using the diffuser the four Z brackets provided should be attached to the side of the heater to enable the heater to be supported by the 'tee' bar and immediately
above the diffuser.
4. ELECTRICAL CONNECTIONS
4.1
230V SINGLE PHASE
WARNING-
400v ac may be present in the terminal boxes due to supplies being taken from different phases.
Please make sure you have read the Safety instructions and that you are a suitably qualified electrician before continuing.
Drawings show connections inside the 2 Terminal boxes on the outside of Slave heaters. For information on wiring the Master heater see instructions enclosed with it.
Do NOT use power tools to undo or do up terminal screws.
Please Note:- Specified cable sizes are for typical installations, correction factors may need to be used when determining actual cable sizes.
Cable Sizes
Mains Cable - Use 1.5mm² 3 Core Mains Cable (see note above).
Additional Slave heaters beyond 5 may be connected
Slave Link Cable- Use 1.0mm² 4 Core Cable.
5. MAINTENANCE
Note:
Before examining or carrying out any maintenance ensure the heater has cooled down and is disconnected from the mains supply. Due to the
design of this heater there may be two different feeds ensure if so both are 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
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.
