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. Determine the cause of overheating and
rectify the fault.
3. Open the service hatch. Locate the red button
next to the terminal box inside the air curtain.
The 2 metre unit is equipped with two red
buttons, one on each terminal box.
4. Press the red button until a click is heard.
5. 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.
Replacing the water coil (W)
1. Shut off the water supply to the unit.
2. Open the vent valve.
3. Open the drain valve.
4. When the water coil is empty, disconnect its

Maintenance
Unit with water heating
The appliance filter should be cleaned
regularly to ensure the air curtain effect and
the 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 service hatch is opened by loosening the
snap fixings located on the bottom of the unit
(turn 90°). The hatch must be held when the
snap fixings are loosened. See fig. 3a and 3b.
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.
