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.

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.
