General guidelines on water supply connection

The pump's water supply connection can be made in one
of the ways listed below.
- Connection to the mains water supply.
- Connection to a tank (gravity-feed).
- Connection to an external pump (force-feed).
The following requirements must be met for all types of
connection.
1) The pump must be supplied by means of a crush-
proof hose of suitable diameter for the pump's intake
connection (see "Technical data").
2) There must be no restrictions or kinks in the hose.
3) A suitable filter must be installed at the pump intake
(see "Technical data").
4) All connections between the unions and the intake
line must be sealed to prevent the pump from suck-
ing in air.

5) The connections and pipes must be suitable for the
operating pressure and the pump delivery rate, and
must comply with the relevant regulations.
6) To ensure operating safety install a relief valve (by-
pass valve) suitable for the pump's technical data and
with a suitable setting downstream of the pump.
7) The relief valve dump line must never be connected
to the pump intake line.
8) Install a pressure damper downstream of the pump
to minimise the water hammer effect in the delivery
pipeline.
