INSTALLATION, OPERATION AND MAINTENANCE INSTRUCTIONS FOR
WARM AIR CURTAIN HEATERS
Catalogue Numbers HSACR3000N & HSACR4500N
PLEASE RETAIN THIS LEAFLET FOR FUTURE MAINTENANCE
MODELS
These units are 990mm 3kW & 4.5kW modular recessed
heaters designed for mounting above doorways and similar
entrances to fit directly into a 600 mm grid in a suspended
ceiling, and may be used as space heaters. (Minimum ceiling
height of 2.2m: maximum height 2.8m).
MOUNTING
When fitting ensure that the air discharge is situated as close
to the door as possible. The recessed air curtains are
designed to fit directly into any suspended ceiling, especially
ceiling tile grid formation. If the grid does not align with the
door then it will need modifying.
The unit should be mounted so that the airflow is not obstructed by
any part of the doorframe.
INSTALLATION
Each unit is provided with 2 brackets with 4 x M6 inserts (2
either end) to allow the unit to be suspended via threaded
rods or wire ties. Please note, when fixing using threaded
rods or wire ties (not supplied) that a suitable structure must
be used ensuring that it can maintain the unit weight.
Ensure that locking nuts are fitted to stop the threaded
bar/wire ties rotating and coming away from the casing. For
dimensions of fixing centres please see figure 1.

ELECTRICAL CONNECTIONS
These units are suitable for connection to a 230/240 Volt 50 Hz
single-phase AC supply. The heaters consume 3kW, 4.5kW
respectively at 240 volts when switched to the full heat position.
HSACR3000 3 kW 12.5A
HSACR4500 4.5 kW 18.75A
Units should only by wired by a competent electrician in
accordance with the latest edition of the IEE wiring regulations.
Ensure that the supply cables and circuit breakers are sufficient
for the air curtain being installed.
The appliance should be connected to the supply via a circuit in
which there is an all-pole switch.
To gain access to electrical connection the recessed grille must
be removed. (The grille is secured to the enclosure of the air
curtain via 4 cross head screws). To remove the grille from the
unit release 2 screws positioned in the corners under the vanes
of air intake then remove the screws on the opposite corners.
Move the grille to the side and lift. Four sets of entry holes are
provided within the casing.
For safety reasons a sound earth connection must always be
made to the unit before it is put to use. The unit should be
wired in accordance with IEE Regulations for the Electrical
Equipment of Buildings.
NOTE: The unit MUST be reliably earthed.
OPERATION
All units are supplied with a remote switch that gives the
following functions; On/off & two heat settings.
For thermostatic control a room thermostat maybe connected.
CONTROLS
To switch on the appliance and operate the blower, depress the
left-hand switch with a control light (marked “FAN”).
When the centre switch only (marked with a single bar) is
depressed the heat output is ⅓of full heat. When the right
hand switch only (marked with a double bar) is depressed the
heat output is ⅔of full heat. When both the centre switch and
the right-hand switch are depressed the full heat output is
available.
MAINTENANCE
Always ensure that the main external electricity supply is
switched off before attending to the servicing of your Claudgen
Screen-Zone heater.
To obtain best results from your heater it is necessary to avoid
the build up of dust and dirt within the unit and on the air inlet
and discharge grills. For this reason regular cleaning is
necessary, paying particular attention to the removal of dirt
build up on the rotor blades. A single drop of light oil should be
applied to the motor bearing from time to time.
PROTECTION (Thermal Cut out)
The units are protected from overheating in the event of fan
failure or an obstruction of the free airflow, by an auto reset
thermal cut out. If this happens the thermal cut out effectively
switches off the appliance. The appliance will not operate until
it has cooled down. If this fault re-occurs again, refer to ‘fault
conditions’.
FAULT CONDITIONS
If the heater will not operate, disconnect it from the mains and
arrange for a certified electrician to attend to investigate the
reason.
TO REPLACE THE FAN HEATER ASSEMBLY
a) Remove the grille.
b) Disconnect the internal wiring from the main terminal
block.
c) Remove the four nuts and washers fixing the fan heater
assembly to the back of the case.
d) The fan heater assembly can now be eased forward and
removed from the heater case.
e) Fit replacement fan heater and reassemble in reverse order.
SPARES
It is essential when ordering spares or replacement parts to
state the model number and the serial number on the rating
place fixed to the top of the unit.
