2. Use cable ties to attach the power supply cable as well as any control and
measuring cables to the riser approximately 0.5 m above the lower flange.
3.
Place two sturdy beams across the well opening.
4. Pull the pump set into upright position with the lifting equipment.
5. Attach the pump set to the crane hook (e.g. mobile crane) by the mounting
plate and lower it into the well until the first pair of supporting clamps rests on
the beams.
6. Remove the mounting plate and fasten it to the second riser.
7. Fasten a second pair of supporting clamps to the second riser.
8. Use the lifting equipment to lower the second riser onto the first riser, and
install it.
9. Undo the first pair of supporting clamps and lower the pump set until the
second pair of supporting clamps rests on the beams.
10. Repeat these steps for every pipe section, lowering the pump set into the well
until the installation depth H
e
is reached.
5.3.1 Attaching the cable ties
The cables shall be fixed to the riser pipe by a cable tie each on both sides of the riser
pipe flange or socket. Attach a cable tie every 3 metres. Implement this arrangement
over the entire length of the riser.
