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.
Residual current circuit breaker (E)
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 not being used for extended
periods of time.
Safety
• For all installations of electrically
heated products should a residual
current circuit breaker 300 mA for
fire protection be used.
• Keep the areas around the air intake
and exhaust grilles free from possible
obstructions!
• During operation the surfaces of the
unit are hot!
• The unit must not be fully or partially
covered with clothing, or similar
materials, as overheating can result
in a fire risk!
• This appliance can be used by
children aged from 8 years and
above and persons with reduced
physical, sensory or mental
capabilities or lack of experience
and knowledge if they have been
given supervision or instruction
concerning use of the appliance
in a safe way and understand
the hazards involved. Children
shall not play with the appliance.
Cleaning and user maintenance shall
not be made by children without
supervision.
