the plumbing
important note:
Before installing the new tap it is essential that
you thoroughly flush through the supply pipes in order to remove
any remaining swarf, solder or other impurities.
Failure to carry out this simple procedure could cause problems or
damage to the workings of the tap.
1. Tee off the cold mains water supply to provide an independent
feed to the water filter.
2. Install the stop-valve (23) inline on the independent feed to
the filter.
important note
: the ends of the stop valve are
not the same. One end has an internal chamfer to connect to
compression pipework; the opposite end has a flat washer face
to suit the G1/2” (1/2” BSP) nut and washer of a flexible hose
(refer to diagram (23) in component list.)
install the filter unit
important note:
The filter unit must be installed inside a
cupboard. Long term exposure to direct light can degrade the
plastic sump leading to eventual failure.
1. Position the filter unit (20) vertically with the hoses at the top,
in its previously determined location.
2. Mark the positions for the two filter unit support screws (22)
using the holes in the filter bracket as a guide.
3. Set the filter unit aside and screw in the two screws leaving the
heads slightly proud (approximately 4mm).
4. Take the G1/2”nut (20.A) at the free end of the filter inlet hose
(blue indicator) and screw it on the G1/2” male outlet thread
of the stop valve (23). Hand tighten the nut firmly using the
attached NutRunna
®
(11) sufficient to make a watertight seal.
Do not overtighten.
5. Take the grey push fit stem elbow (1.A) at the free end of the
cold filtered water hose attached to the tap, wet the stem
before pushing it firmly into the female outlet at the top of the
filter.
important note:
Ensure that the stem connector is
pushed fully home — 10mm of the stem should enter the female
connector.
6. Hang the filter unit on the two screws. If the panel is too thin to
mount the filter securely strengthen the panel with a wooden
batten.
