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. Open the service hatch. Locate the red button
next to the terminal box inside the air curtain.
The 2 and 2.5 metre/6.6 and 8.2 feet units are
equipped with two red buttons, one on the
outside of each terminal box.
4. Press the red button until a click is heard.
5. Reconnect the unit.
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.

should exceed the preset value anyway
the overheating alarm goes off. For more
