Removing the wall insert

CAUTION

Clearance between compressor wheel and wall insert

Serious damage to machinery or property can result from rubbing or jam-
ming of the compressor wheel at the wall insert.

Check that the compressor wheel does not rub against the wall insert
during disassembly/assembly by rotating the rotor.

Fig. 7: Removing wall insert 1

1. Use three press-off screws (90920) to press off the wall insert (77000) until the lifting

device can be fitted.

2. Remove the press-off screws (90920).

3. Remove two studs (72002) in the upper area.

Fig. 8: Removing wall insert 2

4. Unplug cable connector (86515) and fix speed measurement cable in wall insert.

5. Fit bracket (90030) with screws (90955) and nuts (90415).

Fit two plates (90031) and secure with plate (90032), screw (90656) and nut (90432).

6. Secure lifting gear to swivel lifting eye (90231).
