3.4.1 Pipework
Make sure that the pump is not stressed by the
pipework.
The pumps are equipped with flexible connections,
± 5 °, to facilitate the connection of inlet and outlet
pipes. The inlet and outlet ports can be loosened by
turning the union nuts by hand.
1. Carefully screw the inlet and outlet connections
on to the inlet and outlet ports using a pipe
wrench or similar tool.
2. Then fit the connections to the inlet and outlet
holding the connections with one hand, and
tightening the union nuts with the other hand.
See fig. 3.

3.4.2 How to reduce noise in the installation
Vibrations from the pump may be transferred to the
surrounding structure and create noise in the
20-1000 Hz spectrum, also called the bass
spectrum.
Correct installation using a vibration-damping rubber
pad, flexible hoses and correctly placed pipe
hangers for rigid pipes can reduce the noise
experienced by up to 50 %. See fig. 4.
Place pipe hangers for the rigid pipes close to the
connection of the flexible hose.
