5.2.8. Installing the pump
Observe the installation and operating instructions for the pump.
Pump types Drain MTC 32F39, Drain MTC 40, Rexa CUT, Drain
TS 40, Drain STS 40, Drain TC 40
CAUTION!
Stud bolts not removed from the hydraulics (Rexa CUT) can lead
to malfunctions and damage to the pump chamber wall.
Some parts of the fluid can accumulate on the stud bolts,
impairing free access to the intake area and macerator in the
pump.
The intake area and macerator in the pump must be kept free of
deposits.

Discharge pipe
• Remove coarse contaminants in the pump chamber.
• Screw together the pump and discharge pipe outside the pump
chamber using the assembly materials supplied.
• Attach the connection cable to the horizontal section of the dis-
charge pipe using the cable tie supplied. The cable should run from
the pump to the cable tie with slight tension and with no slack.
• Close the shut-off device
• Suspend the chain from the discharge pipe (observing the separate
installation and operating instructions for the chain) and lower the
pump and discharge pipe into the pump chamber until the two cou-
plings have completely engaged with one another.
When lowering the pump, guide it in such a way that it does not
remain suspended on the pump chamber fittings.
NOTE:
For problem-free installation of the pump, it must be twisted later-
ally by around 90° so that it can be guided past the cross member.
• After suspending the pump, check that it is suspended freely and
with sufficient clearance from the pump chamber wall and that it
cannot touch the pump chamber wall.
• Detach the chain from the lifting equipment and suspend it from the
chain hooks in the pump chamber.
CAUTION!
Improper handling of the pump can lead to damage. Only sus-
pend the pump from the installed discharge pipe with a chain,
never from the connection cable.
