MAINTENANCE
WARNINGS:
 Care should be taken to protect pump from frost and freezing,
particularly when located in a loft installation.
 Pump Location
If possible site the pump in a location where in the unlikely event of a
water leak, any spillage is contained or routed to avoid electrics or
areas sensitive to water damage.
1. No routine maintenance is required but provision should be
made for easy access to the pump to allow for repairs due to
normal wear and tear.
2. Disconnect electrical supply before working on pump.
3. Turn off water supplies to the pump and release pressure by opening water outlets
before attempting maintenance.
4. The inlet strainer incorporates a removable gauze filter which may require periodical
cleaning. The frequency of this operation is dependent upon installation conditions.
The strainer is located in the inlet pipework to the pump (see page 8). 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 (see page 8).
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.
5. As water is heated scale deposits are released in areas of hard water (usually south
of a line between the Wash and Bristol Channel), scale can cause the mechanical
seal to stick if left without use for long periods. We recommend the pump is run for
at least 5 minutes every four weeks to “exercise” all working parts. Run on cool
water. See technical specification for note on water temperature. This particularly
applies to guest bathrooms used infrequently.
Cleaners, Disinfectants and Descalents
On installations where chemical disinfectants or descalents are periodically
used, the compatibility of the chemical solution regarding the pump must be
considered.
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
Pump Assist helpline.
