Maintenance

Since fan motors and other components are 
maintenance free, no maintenance other than 
cleaning is necessary, this can vary depending 
on local conditions. Undertake cleaning 
at least twice a year. Grille, impeller and 
elements can be vacuum cleaned or wiped 
using a damp cloth. Avoid the use of strong 
alkaline or acidic cleaning agents.

Overheating

The air curtain unit with electric heater is 
equipped with an overheat protector. If it is 
deployed due to overheating, reset as follows:
1. Disconnect the electricity with the isolating 

switch.

2. Allow the electrical coil to cool.
3. Determine the cause of overheating and 

rectify the fault.

4. Reconnect the power and start the unit.

All motors are equipped with an integral 
thermal safety cut-out. This will operate, 
stopping the air curtain should the motor 
temperature rise too high. The cut-out 
will automatically reset when the motor 
temperature has returned to within the 
motor’s operating limits.

Fan replacement

1. Determine which of the fans is not 

functioning.

2. Disconnect the cables to the relevant fan.
3. Remove the screws securing the fan and lift 

the fan out.

4. Install the new fan in reverse order to the 

above.

Replacing the electric coil

1. Mark and disconnect the cables to the 

electric coil.

2. Remove the mounting screws securing the 

coil in the unit and lift the coil out.

3. Install the new coil in reverse order to the 

above.

Trouble shooting

If the fans do not run, check the following:
1. Operating power supply to the unit; 

check fuses, circuit-breaker, time switch/
thermostat (if any) that starts and stops the 
unit.

2. That the air flow selector is correctly set.
3. That the position limit switch is working (if 

installed).

4. That the intake grille is not dirty.

If there is no heat, check the following:
1. Power supply to electric heater coil; check 

fuses and circuit-breaker (if any).

2. That the heat demand exists; check 

thermostat settings and actual temperature.

3. That the output selector (if any) is set 

correctly.

4. That the intake grille is not dirty.

If the fault cannot be rectified, please contact 
a qualified service technician.

Safety cut-out

(applies฀to฀units฀with฀electric฀heater)

If the installation is protected by means of a 
safety cut-out, which trips when the appliance 
is connected, this may be due to moisture 
in the heating element. When an appliance 
containing a heater element, has not been 
used for a long period and is stored in a damp 
environment, moisture can enter the element.

This should not be seen as a fault, but is 

simply rectified by connecting the appliance 
to the mains supply via a socket without a 
safety cut-out, so that the moisture can be 
driven out of the element. The drying time 
can vary from a few hours to a few days. 
As a preventive measure the unit should 
occasionally be run for a short time when it is 
not being used for extended periods of time.
