INSTALLATLON INSTRUCTIONS
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 sucking in the 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.
