Models
This unit is a 1035mm 6 or 9kW air curtain heater
designed for mounting above entrances but
may also be used as a space heater. It is
supplied complete with remote mounting
control box.
Thermal cut out
The units are protected from overheating in the
event of fan failure or an obstruction of the free
airflow, by thermal cut outs. If this happens the
thermal cut outs effectively switch off the
appliance. The appliance will not operate until the
thermal cut outs are manually re-set. This should be
done by a competent electrician.
Maintenance
ALWAYS ENSURE THAT THE MAIN EXTERNAL
ELECTRICITY SUPPLY IS SWITCHED OFF BEFORE
SERVICING OF THIS SCREEN-ZONE HEATER.
To obtain the best results from the heater it is
essential to avoid the accumulation of dust and dirt
within the unit and on the inlet and discharge grilles.
Regular cleaning is necessary with particular
attention to the fronts and backs of the fan motor
blades. Cleaning of the fan is best carried out with a
soft brush.
Electrical connections
The heater is suitable for connection to a 400-415 volt
3 phase 50Hz supply. With modification the unit can
also be on a 230-240 volt 50Hz supply. For 230-240
volt single phase operation, link terminals L1, L2 and
L3 on the main input terminal block and connect the
supply to L. The heater consumes approximately 6 or
9kW on the full heat setting. The connections to be
made between the heater and the remote control
box are shown on the next page. An earth terminal
is adjacent to the terminal block and is clearly
marked with the symbol . For safety reasons a good
earth connection must ALWAYS be made to the
heater and control box.
The unit must be wired in accordance with IEE
regulations for the Electrical Equipment of Buildings
and the installer should ensure that a suitable fused
isolating switch is connected in the mains supply.
