Start-up (E)
When the unit is used for the first time or
after a long period of disuse, smoke or odour
may result from dust or dirt that has collected
on the element. This is completely normal
and disappears after a short time.
Service, repairs and maintenance
For all service, repair and maintenance first
carry out the following:
1. Disconnect the power supply.
2. Loosen the screws on the intake grille and
remove grille.
3. Lift the front.
See Fig.2.
Maintenance
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.
Undertake cleaning at least twice a year. Inlet
and exhaust grilles, impeller and elements
can be vacuum cleaned or wiped using a
damp 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 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 fully
isolated switch.
2. Allow the electrical coil to cool.
3. Determine the cause of overheating and
rectify the fault.
4. Once the overheat protector has cooled down
the unit can be started again.
Trouble shooting
If the fans are not working or do not blow pro-
perly, check the following:
• The functions and settings of the built-in
control system.
• That the intake grille is not dirty.
If there is no heat, check the following:
• The functions, internal sensor and settings
of the built-in control system.
For units with electrical heating, also check the
following:
• Power supply to electric heater coil; check
fuses and circuit-breaker (if any).
• That the overheat protection for the motors
has not been deployed.
If the fault cannot be rectified, please contact
a qualified service technician.
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!
• The unit may have hot surfaces during
operation and when cooling down!
• The unit must not be fully or partially
covered with clothing, or similar
materials, as overheating can result in a
fire risk! (E)
