6 MAINTENANCE
6.11 Turn off water supplies to the pump and release pressure by
opening water outlets before attempting maintenance.
6.12 Inlet strainer: Incorporated in the strainer is a removable gauze filter which
may require periodic cleaning. The frequency of this operation is dependent upon
installation conditions.
The strainer is located in the inlet pipework to the pump (Fig. 11). The gauze filter
is removed as follows:-
a) Isolate pump electrically.
b) Release all system pressure.
c) Isolate water supply.
d) Remove screwed hexagonal plug from strainer body taking care to collect or
absorb any residual water (Fig. 11).
e) Remove and clean stainless steel gauze filter.
f) Reassemble gauze and secure plug tightly.
g) Turn on water supplies, connect power supply and test.
6.13 Water scale: As water is heated scale deposits are released in areas of hard
water, scale can cause the mechanical seal to stick if left without use for long
periods. The pump must be run for at least 5 minutes every four weeks to
“exercise” all working parts. Run on cool water. See Section 7 - Technical
Specification for note on water temperature. This particularly applies to guest
bathrooms used infrequently.
6.14 Cleaners, Disinfectants and Descalents:
Acid based descalents and aggressive cleaning agents must not
come into contact with the pump. The pump must be removed from
the system prior to the use of these products. The system should be
flushed to remove all chemicals before the pump is re-connected.
If in any doubt as to the suitability of the chemical solutions, please
contact our PumpAssist helpline on 0844 98 000 97.
