Maintenance
All units
Since fan motors and other components are
maintenance-free, no maintenance other than
cleaning is necessary. The level of cleaning can vary
depending on local conditions. It is recommended
to clean every 6 Months (individual conditions may
vary).
General Air Curtain Maintenance steps are as follows:
■
Regularly inspect the air curtain for any visible
signs of damage or wear, such as frayed or loose
wires, bent or broken components, or damaged
blades.
■
Clean the air curtain regularly to remove any
dust, dirt, or debris that may have accumulated
on the unit. This can typically be done by wiping
the unit down with a clean, dry cloth or using a
soft-bristled brush to gently remove any dirt or
debris.
■
Check the air filter regularly and replace it if it
is dirty or damaged. A dirty air filter can reduce
the efficiency of the air curtain and may need to
be replaced more frequently.
Check the airflow of the air curtain and make
■
sure it is operating at the correct speed and
pressure. If the airflow is too low or too high, it
can affect the effectiveness of the air curtain.
■
If the air curtain is not working properly or is not
functioning at all, it may need to be serviced
or repaired. In this case – follow troubleshooting
steps listed in the manual. It is best to consult the
manufacturer or a professional technician for
assistance.
Overheating
The air curtain unit with electrical heating is
equipped with overheating protection. If it is
deployed due to overheating, reset as follows:
1. Disconnect the electricity supply with the fully
isolated switch.
2. Allow the electrical coil to cool.
3. Determine the cause of overheating and
rectify the fault.
4. Reconnect the air curtain.
All EC 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 from the relevant motor
on the fan deck.
3. Remove the screws securing the fan deck and
lift the fan deck out.
4. Install the new fan deck as above in reverse order.
Replacing heating elements (VE)
1. Disconnect and remove the fan deck
2. Mark and disconnect the cables to the electric
elements.
3. Remove the mounting screws securing the
electric elements in the unit and remove the
faulty element.
4. Replace faulty electric element.
5. Install the electric elements in reverse order to the
above.
Residual current circuit breaker (GFI)
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 an extended 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 main
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 brief time when it is not
being used for extended periods of time.
