Feed valve with strainer
The nylon bodied solenoid feed valve
incorporates a small nylon strainer which is
a push fit into the inlet of the valve. With a
new plumbing installation, residual loose solid
material in the pipework could partially block
the strainer after start-up.
If for this, or any other reason, a restriction of
the water flow is suspected (outside of supply
pressure considerations), it is possible to clean
the strainer in the following manner:-
MS
1. Ensure the I/O/II on the fascia of the unit is in the
'0' (Off) position.
2. Isolate the electrical supply to the unit.
3. Turn off the water supply to the Unit.
4. Undo the nylon nut connecting the flexible
connection to the valve inlet.
5. The strainer can be removed using 'long-
nosed' pliers to grip the centre flange
provided on the strainer for this purpose.
6. Withdraw the strainer and wash it with cold
running water.
7. Replace the strainer and reconnect the nylon
nut / flexible connection.
8. Turn on water supply.
9. Reconnect electrical supply to allow unit to
operate.
Note: Always replace the strainer after cleaning
as it is required to prevent material lodging in
the valve seat or blocking the small flow control
restrict or which is fitted in the valve.

Drain pump
The drain pump is a sealed unit and should not
be dismantled. To remove / replace the pump:-
1. Place a bucket below the pump to catch any
water remaining in the housing or pipework.
2. Undo the screws holding the pump body
to the feed & drain manifold and remove
it - any water trapped in the pump will be
released at this point.
3. Fit the replacement pump by following the
above steps in reverse order. Ensure that the
pump is correctly seated and that it mates
correctly with the feed / drain manifold and
gasket.

Bottom access panel
An access panel has been provided at the
bottom of the unit, held in place by screws.
Removal of the panel allows access to the drain
pump and feed / drain manifold assembly.
