the air stream and make it bend inwards
into the premises (when the premises
are heated and the outdoor air is cold).
The air stream should therefore be
directed outwards to withstand the load.
Generally speaking, the higher the load,
the greater the angle that is needed.
Basic setting of fan speed
The fan speed when the door is open is
set using the speed control. Note that
the air flow direction and speed may
need fine adjustment depending on the
loading of the door.
Filter (W)
The heating coil is protected by an 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 base plate/service hatch is opened
by loosening the snap fixings located
on the down side (turn 90°) and then
loosening the base plate from the rim.
See fig. 3 and 4.
3. After service, repair and maintenance
close the base plate/service hatch and
make sure that the snap fixings lock
properly.
Maintenance
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.
2.The base plate/service hatch is opened
by loosening the snap fixings located
on the down side (turn 90°) and then
loosening the base plate from the rim.
See fig. 3 and 4.
3 Remove the filter and vacuum clean
or wash it. If the filter is clogged, it may
need to be changed.

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, impeller and
elements 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 with electric heater
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.
Reset is performed as follows:
1. Locate the red button inside the
air curtain unit. This is visible and
accessible by opening the base plate.
The button is located outside the
connection box. On the 2-metre
variant, a red button is located
outside each connection space.
2. Press the red button until a click is
heard.
3. Connect the air curtain again.
The motors in all the air curtain units
have a built-in thermal safety cut-out
to protect against overheating. This will
reset automatically once the motor has
cooled.
