Installing the Filter Tap
Position the Filter Tap at the back of the sink where there is a 45 mm wide flat area within the draining areas of the sink.
The recommended position is over one corner of the bowl. Make sure the selected position allows the spout to overhang
the sink bowl.
The cutout size is 25 mm. Mark the centre of the new Filter Tap position on the sink with a centre punch. Drill out the
centre of the hole to allow the screw of a sheet metal punch to pass through the sink. Use a 25 mm sheet metal punch to
neatly cut the hole.
Remove the nut and washer from the base of the Filter Tap, and pass the tubing through the sink until the Filter Tap sits
upright within the hole you just created in the sink surround.
Orientate the Filter Tap so that the activating lever is away from the sink bowl. Slide on the washer and nut from beneath
the sink, and tighten the nut to secure the Filter Tap firmly into place.
Take care, when bending plastic tubing, to prevent it from kinking or crushing on a bend.
Do not connect the tubes in any other arrangement than that described here. The filter cartridge and the Filter Tap have
directional flow connections that will not work if connected incorrectly. Incorrect installation will void any product warranty.
Note that the flow direction of the filter housing is indicated on the side of the filter housing. The housing will require the JG
1/4” x 3/8” fittings to be screwed in place (use thread sealing tape) on both the inlet and outlet ports prior to the fitting of the
white tubes.
Measure and cut the white tube from the Filter Tap to length so that it runs around the back of the cupboard to the outlet
side of the filter housing. Use a tube cutter to cut the end off the tubing neat and square, so that there are no rough edges.
Shake the tube vertically to allow any debris to fall out of the tube before inserting it into the filter head.
Push this end of the clear tube firmly into the John Guest socket on the outlet side of the filter head.
It must push in at least 10 mm. Test the connection by trying to pull the tube out. If it comes out, re-insert it so that it won’t
come out when pulled against.
Use the JG Elbow supplied, to connect the ends of the BLUE and RED tubes together.
Installing the DNR Valve
The DNR valve must be installed between the main isolation valve and the filter cartridge. Check the direction of flow on
the DNR valve is in line with the arrow marked on the side of the valve.
The DNR valve must be connected downstream of an accessible isolation tap. The 1/2”M- BSP threaded section on the
inlet end of the DNR valve may be connected directly to an isolation tap.
Take the one metre of white tube from the filter kit.
Measure and cut the tube from the DNR valve to length, so that it runs around the back of the cupboard to the inlet side of
the filter housing. Leaving a little extra slack in this line for the connection of the DNR valve.
Insert the tube end into the (JG) fitting on the side of the DNR valve.
Insert the other end of tube into the (JG) fitting on the Inlet side of the filter head. Note the directional arrows on the body of
the Valve. It must end up connected so that they point in the direction of the Flow. (See Installation Diagram on Pg 4.)
