Switch off the power supply before you
start any work on the product.
‐
Make sure that the power supply can-
not be switched on accidentally.
WARNING
Electric shock

‐
Do not lower the product by the power
cable.
Use appropriate lifting equipment to lower
the pump into the borehole or basin.
Observe local regulations concerning limits
for manual lifting and handling.
We recommend that you secure the pump
with an unloaded straining wire before low-
ering it into the borehole or basin.
1. Note the weight of the product stated on the pump
and motor nameplates.
2. Follow one of these procedures according to the
weight of the product and local regulations:
a. If manual lifting is allowed, grip the pump by
the outlet chamber or attach lifting wires to the
wire hooks.
b. If manual lifting is not allowed, attach lifting
wires to the wire hooks and use appropriate
lifting equipment. Remove the lifting wires
before the product is lowered below ground
level.
3. Lower the pump carefully into the borehole or
basin by holding on to the riser pipe. Take care
not to damage the power cable and the
submersible drop cable.
4. Fasten the drop cable to the riser pipe with cable
clips as you connect the pipes.
Securing the pump with a straining wire
Do not use the straining wire to carry the
load of both pump and riser pipe when you
lower the pump or pull the pump out of the
borehole.
1. Secure the pump with an unloaded straining wire.
