ALWAYS ENSURE THAT THE MAIN EXTER-
NAL ELECTRICITY SUPPLY IS SWITCHED
OFF BEFORE COMMENCING ANY MAINTE-
NANCE ON THIS HEATER.
To obtain the best results from the heater, it is es-
sential to avoid the accumulation of dust and dirt
within the unit on the air inlet and discharge grilles.
For this reason regular cleaning is necessary, pay-
ing particular attention to the removal of dirt build up
on the rotor blades.
Cleaning of the fan is best carried out with a soft
brush.
The product should be serviced annually.
Servicing shall be undertaken by a competent per-
son.
7.2 General
If the air curtain does not operate after switching on,
then a suitably competent service engineer should
be called to identify the nature of the fault.
All Air Curtains are fitted thermal cut - outs and motor
thermal protection.
Other faults in relation to the element, motor and
wiring should be identified using conventional fault
finding techniques.
In the event that electrical components are replaced,
please ensure that electrical safety checks in ac-
cordance with the regulations in force in the country
of use are undertaken.
7.3 Thermal and fault protection
The units are protected from overheating in the
event of fan failure or an obstruction of the free air-
flow by thermal cut - outs.
If this happens, the thermal cut - outs effectively
switch off the appliance by disconnecting power to
the control circuit. The appliance will not operate
until the thermal cut - outs are manually reset. This
should be done by a competent electrician.
The heaters are also protected by thermal fuses to
prevent catastrophic failure. The thermal fuse will
trip and disconnect power to the affected heater.
Thermal fuses are not resettable.
7. Servicing & Maintenance
7.1 Maintenance
7.4 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.
7.5 Replacing Fan Heater Assembly
Remove the lid.
Disconnect the internal wiring from the main terminal
block. Remove the four nuts and washers fixing the fan
heater assembly to the back of the case. The fan heat-
er assembly can now be eased forward and removed
from the heater case. Fit replacement fan heater and
reassemble in reverse order.
7.6 Noise Levels
Sound pressure levels dBA are measured at a 3m dis-
tance with a single air curtain mounted at its maximum
mounting height, operating in a room with average
acoustic characteristics as defined in CIBSE Guide B5
(reverberation time 0.7s at 1kHz) and a room size
equivalent to 8 air changes per hour (ac/h). The dB
meter must not be in the direct airflow of the heater.
Care needs to be taken when selecting air curtains for
an installation as noise levels can be several dB higher
if the mounting height is reduced, if the room is more
‘ live ’ (i.e. hard surfaces, no furnishings or absorbent
materials), if the room is smaller than 8 ac/h equivalent
or a combination of these factors. Noise levels will also
increase if more than one air curtain is installed at the
same doorway (e.g. +3dBA for 2 equal point sources:
direct field).
7.7 Spares
It is essential when ordering spares or replacement
parts to state the model number and the serial number
on the rating label fixed to the top of the unit.
