Where to use Check Valves
and Foot Valves
Installations with a suction lift require a good quality foot valve to avoid loss of prime.
Installations with flooded suction require a gate valve so water supply can be turned
off for pump removal and servicing.
Installations with overhead tanks and pipe work
require a one-way check valve to avoid water
draining back past the pump while not in operation
and causing possible pump damage.
Priming and Operation
1. Ensure outlet nearest to
pump is open.
2. Fill pump body and suction
line through priming plug
hole located above suction
inlet and replace plug.
3. Switch on.
4. Prime should establish almost
immediately with a strong flow
of water, however, in some
installations it may be necessary
to repeat the above operation to
remove all air from the
system.
WARNING:
DO NOT RUN DRY.
DO NOT RUN WITH LOSS OF PRIME.
DO NOT PUMP WATER CONTAINING ABRASIVE MATERIALS.
