6 MAINTENANCE
6.11 Turn off water supplies to the pump and release pressure by
opening water outlets before attempting maintenance.
6.12
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.
6.13
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 Pump Assist helpline on 0844 98 000 97.
