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: The inlet strainers may require periodical cleaning. The frequency
of this operation is dependent upon installation conditions.
The strainer is located in the inlet fitting of the pump casing (Fig. 14) and is
removed as follows:-
a) Isolate pump electrically.
b) Release all system pressure.
c) Isolate hot and cold water supplies via the integral pump isolating valve
located in the flexible hoses (see Section 3 - Pump Connections).
d) Disconnect the hot and cold flexible inlet hoses only at the joint where the
hoses connect to the pump inlet fittings (see Section 3 - Pump Connections).
e) Clean strainers.
f) Reassemble pipework.
g) After maintenance is completed refer to commissioning section for instructions
on re-starting pump.
6.13 No other routine maintenance is required.
6.14
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.
