Service, repairs and maintenance

For all service, repair and maintenance first 
carry out the following:
1. Disconnect the power supply.
2. The service hatch is opened by slackening 

off the screws in the side of the unit.

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.

The air curtain is equipped with a post-
running thermostat who makes the fans blow 
on middle speed until the electric coil is cold.

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.

Residual current circuit breaker 
(applies to units with electric heater) 

When the installation is protected by means 
of a residual current circuit breaker, 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 or 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 
eliminated from 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
