Starting The Pump
a)
Ensure all outlets are closed, turn power supply ‘on’ - pump will start, pressurise
the system then stop.
b)
Open and close all outlets in turn associated with the pump, (including w/c
systems) allowing water to flow from each outlet until all air is purged. As each
outlet is opened and closed, the pump will start and stop respectively.
Note: After closing the outlet there will be a small delay time before the pump
stops, which is normal.
Any tap or control valve within the system when opened and closed will now turn
the pump on/off. Providing this is the case the system is now operating correctly.
c)
Carefully check pump and pipework for leaks whilst pump running and stationary
before leaving the installation unattended.

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 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 strainers may require periodical cleaning. The frequency of this operation is
dependent upon installation conditions.
The strainer is located in the inlet assembly of the pump casing (see pump
connection section) 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 and release hose nuts connected to the pump (see pump
connections section).
d)
Remove M4 screws (2 off) from inlet assembly, lift brass inlet fitting (with ‘O’-ring)
and clamp away from pump casing (Fig. 15).
e)
Remove strainer with long nose pliers noting location lug position upon removal
(Fig. 15) and clean thoroughly.
f)
Refit strainer taking care to position lug in body inlet port location slot (Fig. 15)
and re-assemble pipework. Tighten M4 clamp screws to 1.5 Nm torque.
g)
After maintenance is completed refer to commissioning section for instructions on
re-starting pump.
