INSTALLATION, OPERATION AND MAINTENANCE INSTRUCTIONS FOR
WARM AIR CURTAIN HEATERS
Catalogue Numbers HSAC3000X & HSAC4500X
PLEASE RETAIN THIS LEAFLET FOR FUTURE MAINTENANCE
MODELS
These units are 635mm 3kW & 4.5kW modular heaters designed for
mounting above doorways and similar entrances, and may be used as
space heaters. 990mm 4.5kW and 990mm 6kW modules are also
available.
MOUNTING
When mounted over a standard shop doorway the unit should be
fitted as low as possible and not more than 2.3 meters from ground
level. A single unit will provide reasonable coverage for a one metre
doorway, and for wider doorways units can be mounted end to end.
The unit should be positioned so that the airflow is not obstructed by
any part of the doorframe.
INSTALLATION
Carefully unpack the unit and remove the top cover fixing screws.
The heater may be mounted using the mounting bracket provided.
Remove mounting bracket screws, allowing the mounting bracket to
be removed from the unit. Making sure that the mounting bracket is
horizontal, fix the bracket to the wall using 4 x No 8 wood screws.
Place the unit on the mounting bracket ensuring the washer is
positioned as in diagram.
Tighten screws to hold the unit at the required angle.
Fig 2 WALL BRACKET ASSEMBLY
The heater may also be mounted directly onto a suitable wall or
bearer by four No 8 wood screws through the holes provided in the
back of the unit casing. Keyhole slots are provided for the top two
fixings (fig 1).
ELECTRICAL CONNECTIONS
These units are suitable for connection to a 230/240 volt 50 Hz single
phase ac supply, except for the 220 volt models. The heaters
consume 3kW & 4.5kW respectively at 240 volts when switched to
the full heat position.
Model HSAC3000X (see fig 2) – 3 kW
Model HSAC4500X (see fig 3) – 4.5 kW
The appliance should be connected to the supply via a circuit in
which there is an all-pole switch. Test for correct operation and
refit the cover.

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
The right hand switch connects the mains supply to the fan motor
(giving a cool airflow) and energises the heat control switches.
HEAT CONTROL HSAC3000X
When the centre switch (marked with a single black dot) is depressed
the heat output is 1kW. When the left-hand switch (marked with two
black dots) is depressed the heat output is 2kW. When both switches
are depressed the heat output is 3kW.
HEAT CONTROL HSAC4500X
When the centre switch (marked with a single black dot) is depressed
the heat output is 1.5kW. When the left-hand switch (marked with
two black dots) is depressed the heat output is 3kW. When both
switches are depressed the heat output is 4.5kW.
MAINTENANCE
Always ensure that the main external electricity supply is switched
off before attending to the servicing of your Heatstore Warm Air
Curtain.
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 in the event of fan failure, or an obstruction
of the free airflow, by thermal PTC Self Hold Cut-outs. Having
tripped, the PTC cut-out remains open, effectively switching off the
heating elements, as long as mains power is available inside the
appliance.
TO RESET THE PTC SELF-HOLD CUT-OUT
DO NOT ADJUST BY HAND ANY COMPONENTS
a) The cut-out is reset by switching OFF mains power to the
appliance.
b) Allow the appliance to cool for 20 minutes.
c) Restart, switch ON the appliance. If the cut-out trips again a
qualified electrician should be consulted.
TO REPLACE A SWITCH
a) Remove the top cover.
b) Release the three fixings which secure the switch bracket to the
right hand side of the main case.
c) Remove the push-on connectors, noting their position.
d) Remove by compressing the plastic retaining tabs, and lifting
out the switch.
e) Insert the new switch, refit and push on connectors in the
correct order, test and reassemble.
TO REPLACE THE FAN HEATER ASSEMBLY
a) Remove the top cover.
b) Disconnect the internal wiring from the main terminal block and
earth stud.
c) Release the three fixings which secure the switch bracket to the
right hand of the main case.
d) Remove the four nuts and washers fixing the fan heater
assembly to the back of the case.
e) The fan heater assembly can now be eased forward and
removed from the heater case.
f) 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.
In the interest of progress the Company reserves the right to vary

NOTE: DO NOT COVER any of the air inlet or outlet grills, at any
time.
