7.5.2 Reassembling the motor section
DANGER
Wrong screws/bolts
Explosion hazard!
▷
Only use original screws/bolts on explosion-proof submersible mixers.
NOTE
Before reassembling the motor section, check that all joints relevant to explosion
protection (flamepaths) are undamaged. Components with damaged flamepaths must be
replaced. Only use original spare parts made by KSB for explosion-proof submersible
mixers. The flamepaths are shown in the relevant drawings. (⇨ Section 9.2 Page 48)
All screwed connections closing off the flameproof enclosure must be secured with a
thread-locking agent (Loctite Type 243).
