Tighten the cable gland. Ensure the cable is secure within the gland.
Replace the terminal box.
8. BEFORE USING
WARNING - Do not run pump dry. Purge water thoroughly through system before
switching on pump electrical supply.
DO NOT TURN ON THE ELECTRICITY SUPPLY
1. Turn on water supply. Allow system to fill.
2. Immediately inspect for any leaks.
3. With pump not running, allow maximum water flow, for example 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 2 minutes, to flush out all debris and ensure
air is thoroughly purged from system.
4. SWITCH ON ELECTRICITY SUPPLY TO PUMP.
Again operate pump in both full hot and cold modes for about 2 minutes.
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 “push fit” connectors are fully inserted.
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.
9. SERVICING
1. If the flow from the shower drops below its normal performance it may be necessary
to clean the pump filters. Blocked filters 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 turn off service valves, remove and clean strainers (see 6 Connecting
Pump).
2. 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.
10. FAULT FINDING
A If pump fails to start, check the following:
1. Electricity supply and fuse (5A rating or 10A on BP130D).
2. Are isolating valves turned on?
3. Are the pump filters blocked, causing insufficient flow to the pump? Turn off service
valves or isolating valve; clean the strainers; replace, and turn on water supply.
4. Is pump correctly installed with outlets (flow switches) vertical?
5. Is there sufficient water flow to operate the flow switches 0.5 litres per minute?
6. If, for any reason, the motor overheats, the built-in thermal protection will turn off the
motor. It will automatically reset once the motor has cooled sufficiently.
