The free end of the cable must not be
submerged as water may penetrate into
the motor.
The guide rails must not have any axial play as this
can cause noise during operation.
Proceed as follows:
1.
Drill mounting holes for the guide-rail bracket on
the inside of the pit and fasten the guide-rail
bracket with two screws.
2.
Place the auto-coupling base unit on the bottom
of the pit. If the bottom is uneven, the auto-
coupling base unit must be supported. Use a
plumb line to establish the correct positioning.
Fasten the auto coupling with expansion bolts.
3.
Connect the outlet pipe in accordance with the
generally accepted procedures. Avoid exposing
the pipe to distortion or tension.
4.
Place the guide rails on the auto-coupling base
unit and adjust the length of the rails to the
guide-rail bracket at the top of the pit.
5.
Unscrew the guide-rail bracket. Insert the
expansion dowels into the holes. Fasten the
guide-rail bracket on the inside of the pit. Tighten
the bolts in the expansion dowels.
6.
Clean out debris from the pit before lowering the
pump.
7.
Fit the guide shoe to the pump outlet. Grease the
gasket of the guide shoe before lowering the
pump into the pit.
8.
Slide the guide shoe along the guide rails
and lower the pump into the pit using the chain
secured to the lifting bracket. When the pump
reaches the auto-coupling base unit, pull the
lifting chain towards the guide rail several times
to shake off any substances. When the chain is
unstrained, the pump automatically connects to
the auto-coupling unit.
9.
Hang up the end of the chain on a suitable hook
at the top of the pit. Make sure that the chain is
straight but not strained.
10. Adjust the length of the power cable by coiling it
up on a relief fitting to ensure that the cable is not
damaged during operation. Ensure that the
coiled cable cannot fall into the pit. Make sure
that the cables are not sharply bent or pinched.
11. Connect the power cable and the control cable, if
any.
