Filter (W)
The water coil is protected against dirt and blockage by
an internal air filter which covers the coil face.
Service, repairs and maintenance
For all service, repair and maintenance first carry out the
following
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. After the service, repair and maintenance reattach
the front hatch. Place the hatch at the lower edge
with the bent edge and fasten on top with screws.
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 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 condi-
tions. 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 overhea-
ting, reset as follows:
1. Disconnect the electricity with the fully isolated
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 connection 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.
Temperature control
See control pages.
Replacing the water coil (W)
1. Shut off the water supply to the unit.
2. Disconnect the connections to the water coil.
3. Remove the mounting screws securing the coil in
the unit and lift the coil out.
4. Install the new coil in reverse order to the above.
