Maintenance
Since fan motors and other components
are maintenance free, no maintenance
other than regular cleaning is necessary.
The frequency of cleaning can vary
depending on local conditions, but
undertake cleaning at least twice a year.
Inlet and exhaust grilles and impeller
can be vacuum cleaned or wiped using a
dry cloth. Use a brush when vacuuming
to prevent damaging sensitive parts.
Avoid the use of strong alkaline or
acidic cleaning agents.
Overheating
The air curtain unit 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.
Once the power has been disconnected
the unit can be started again.
Troubleshooting
If the fans are not blowing enough,
check the following:
1. Operating power supply to the unit;
check fuses, circuit-breaker, time
switch that starts and stops the unit.
2. That the intake grille is not dirty.
If there is no heat, check the following:
1. That the heat demand exists;
check thermostat settings and actual
temperature.
2. That the overheat protection for the
motors has not been deployed
If the fault cannot be rectified, please
contact a qualified service technician.
