12.4.1 Safety Information
Disconnect all parts of the system and secure them against being switched
on again before any wiring and maintenance work!
The housing must only be opened once the motor has come to a standstill.
Risk of injury!
Check the function of all components after completing the work.
12.4.2 Opening the Service Hatches
Stand on a solid surface to carry out maintenance on the Airblock FG, e.g. a
lifting platform. Do not use a ladder! Do not stand within the swivel range
of the hatch!
Caution!
Two people are needed to open the service hatch

! The hatch
weights up to 20 kg depending on the model. Never open the service hatch
further than 90°!
Steps:
1. Rotate the turning bolt (4 or 6 no. per service hatch) 90° inwards using
the square box spanner enclosed.
2. Lower the service hatch until the safety hook automatically hooks into the
lug of the housing connecting strut; the safety hook prevents the service
hatch suddenly flapping downwards.
3. Lift the service hatch slightly; push back the safety hook until it can be
moved past the lug of the housing connecting strut.
4. Carefully lower the service hatch to the desired position.
