Overheating
The average temperature of the outlet air is
restricted to +40 °C on the electrical unit.
The air curtain unit with electric heater is
equipped with an overheat protector. If this is
deployed due to overheating, reset as follows:
1. Disconnect the electricity using the
omnipolar switch.
2. Allow the electrical coil to cool.
3. Determine the cause of overheating and
rectify the fault.
The motors in all the air curtain units
have a built-in thermal safety cut-out to
protect against overheating. This will reset
automatically once the motor has cooled.
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.
Changing the electric coil/battery
1. Mark and disconnect the cables to the
electric coil/battery.
2. Remove the mounting screws securing the
electric coil/battery in the unit and lift the
electric coil/battery out.
3. Install the new electric coil/battery in
reverse order to the above.
Troubleshooting
If the fans are not working or not blowing
enough, check the following:
Operating power supply to the unit;
s
check fuses, circuit-breaker, time
switch/thermostat (if any) that starts
and stops the unit.
That the speed regulator is correctly
s
set.
That any position limit switch is
s
working.
That the thermal safety cut-out for the
s
motors has not been deployed.
That the intake grille/filter is not dirty.
s
If there is no heat, check the following:
Check that the settings for the
s
thermostat, switches etc. are set so that
the unit can produce heat.
For units with electrical heating, also check
the following:
Power supply to electric heater coil;
s
check fuses and circuit-breaker (if
any).
That the overheat protection has not
s
been deployed.
For units with water coil, also check the
following:
That the water coil is bled.
s
That there is a sufficient water flow.
s
That the incoming water is sufficiently
s
hot.
If the error cannot be fixed, please contact a
qualified service technician.
Safety cut-out
If the installation is protected by means of
a safety cut-out (circuit breaker), which
trips when the electrical unit is connected,
this may be due to moisture in the heating
element. When a unit 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
