Fitting Twin Under-sink Water Filter System 1025PS1 + WC04

1025PS1 and WC04 Twin Under Sink System

Fitting Your Dedicated Tap 

Place the plastic or rubber washer from the base of the new tap, in the corner of the sink, in the flat
section, check under the sink to see where the thread of the tap will go, making sure there are no other
obstructions where the tap thread will be.

Use a nail or centre punch to mark the centre of hole. Use a battery drill to drill the holes, drill slow and added a few drops of water as you go. Start with a small drill 5mm or so, and work your way up using about 4 different drills until 12mm.

Fit the sink tap, put the big hard washer and nut under the sink. Tighten up, doesn’t matter which way the tap faces.

Install Water Connections 

Turn off the water supply and release water pressure by opening up a cold tap. Check to make sure
which one of the braided lines or taps under the sink is the cold water line.

Undo the cold water hose of the wall tap or fitting, fit the John Guest tee shut-off tap and reconnect
the cold water line to the other end.

Cut a short piece tubing to from the shut-off tap to the inlet side of the grey inline pressure limiting valve. Check the flow direction on the valve.

Screw the filter system to the inside of cupboard or it can stand up by its self on the base of the
cupboard, leaving it loose to make removing easy also leave the plastic tubing long enough to bring the
system out onto the floor as it makes servicing the filters easier.

Run the tubing from the outlet of pressure limiting valve to the inlet on the filter system, push the
tubing all the way in then pull out to lock.
Fit the tube from the new sink filter tap to the outlet side of filter.

Turn the little blue service tap handle off, which is across the tube.

Check all connections.

Turn the cold water supply on.

Turn on the new sink filter tap and leave on to allow the air out of the system.

Turn on the blue service tap and flush the new filter for 2 – 3 minutes, turn off and on the sink filter tap,
to let air out. Turn off sink tap and check for leaks.

As the filters are so fine you may have some air bubbles in the water for a few days, this will go away.

Changing Filters 

The main thing when changing filters is to turn off the service tap and open the sink tap to release the
water pressure.

Always lubricate the housing o-rings, a little vegetable oil or cooking oil will do (do not
use petroleum based lubricants).

When turning the water back on, make sure the filter tap on the sink
is open, otherwise air will get trapped in the filters for a few days – this doesn’t affect the water quality
but the water may appear cloudy from air bubbles.

After turning on blue service tap, flush the new filter for 2 – 3 minutes, turn off and on the sink filter tap to let air out.

Turn off sink tap and check for leaks.

Tighten the housings by hand only – the spanner is used to solely undo the housing sumps.
