Maintenance

Unit with water heating
The appliance filter should be cleaned regularly
to ensure the air curtain effect and heat
emission from the device. How often depends
on local circumstances. A clogged filter is not a
risk, but the appliance function can fail.
1. Disconnect the power supply.
2. The front hatch is removed by removing the
screws on the top of the unit and then detach
the bent edge at the bottom. (Fig.3)
3. Remove the filter and vacuum clean or wash
it. If the filter is clogged or damaged, it may
need to be changed.
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. 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 electrical heating is
equipped with an overheat protection. If it is
deployed due to overheating, reset as follows:
1. Disconnect the power supply with the isolator
switch.
2. Determine the cause of overheating and
rectify the fault.
3. Remove the front hatch.
4. Press the red button located inside the air
curtain unit, at the inner gable of the terminal
box.
5. Reattach the front hatch and connect the unit
again.
All 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.
