Ensure the pump is primed as described in the priming section before starting,
damage to the shaft seal will result otherwise. See Section 5 - Commissioning.

Pipework - General
1.17
Secure pipework: Ensure pipework to and from pump is independently
supported & clipped to prevent forces being transferred to inlet and outlet
branches of pump.
1.18
Flux: Solder joints must be completed and flux residues removed prior to pump
installation
(flux damage will void any warranty).
1.19
Pipework design: Care should be taken in the design of pipework runs to

o
bends.

manufactured from plastic.
1.21

o
. They must be installed as
straight as possible.
