Before Using the Pump
WARNING
•
Do not let the pump run dry.
•
Purge water thoroughly through the system before switching on the electricity
supply to the pump.
•
Do not switch on the electricity supply.
1. Turn on the water supply. Allow the system to fill.
2. Immediately inspect for any leaks.
3. With pump not running, allow maximum water flow, e.g. remove handset from shower
hose, letting the shower hose hang into the shower tray or bath. Operate maximum
hot and cold flow for at least 5 minutes each, to flush out all debris and ensure air is
thoroughly purged from the system. For fixed head showers remove the shower rose
and connect a length of hose, hanging into the shower tray or bath.
4. Switch on the electricity supply to the pump. Again operate the pump in both full hot
and cold modes for about 5 minutes each.
5. With
the
pump
operating,
carefully inspect again for any leaks from all connections on
both hot and cold feed pipes to the pump and to the system.
After hot water has been run for several minutes, check all hot water connections and
make sure that there are no leaks.
6. The first few times the pump is used, the insulating varnish used on the pump motor
may give off an odour. This is perfectly normal and will diminish with use.
7. In hard water areas scale build up can cause the pump parts to stick if the pump is not
used for long periods.
8. It is recommended that the pump is run for 5 minutes or more, at least once every four
weeks in order to prevent the pump seizing.
Servicing
The flexible pump hoses, dependent on water temperature and mechanical stress, can
deteriorate with age. We recommend that all flexible hoses and connections are inspected
at least every 6 months. Replace as necessary to prevent leaks.
Only hoses designed to
be used with this product should be used.
The service helpline will be able to advise of
a local stockist of hoses.
If the flow from the shower drops below its normal performance, it may be necessary to
clean the pump strainers. Blocked strainers are common on initial installation of pumps, or
in new buildings where the use of jointing compounds, tapes, flux and other debris can be
flushed through the system.
In this event, close the service valves, remove and clean the strainers.
Check that if the shower has a hose, it is not twisted or kinked and restricting the water
flow.
Purge any air in the system. With the pump not running allow maximum flow by removing
the shower handset and allowing the hose to hang into the shower tray or bath. Operate
maximum hot and cold flow for at least 5 minutes each. For fixed head showers remove
the shower rose and connect a length of hose, hanging into the shower tray or bath.
A common cause of poor shower performance is a clogged shower head/handset, so
regular cleaning and descaling is important - this applies particularly to hard water areas.
