towards the guide rail several times to shake off any foreign
substances (fig. Connecting the pump to auto coupling). When
the chain is unstrained, the pump connects automatically to the
auto-coupling unit (fig. Submerged installation on auto
coupling).
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.
Fasten the relief fitting to a suitable hook at the top of the pit.
Make sure that the cable is not sharply bent or pinched.
11. Connect the power- and control cables, if any.
The free end of the cable must not be submerged as
water may penetrate into the motor.
