8. FITTING THE MIXER VALVE
1. A rectangular hole between 200mm and 160mm
should be large enough to fit the mixer valve. The
valve should be fixed to the wall between 85mm
and 95mm below the finished surface of the shower
(Fig 1).
2. The supply pipework can be plumbed from above
or below but must finish at the suitable connections
which should be at approximately 150mm centres,
provision should be made for some adjustment on
fitting valve (Fig 2).
3. Fit a male
¾
BSP elbow to 15mm or 22mm
compression (not supplied) to both hot and cold
inlets and the outlets, apply PTFE tape to seal the
threads.
NOTE: It is recommended to apply PTFE tape to all
threaded connections (boss white or other sealing
compounds are not suitable).
The valve can be used as either a 2 Way or a 3 way
valve depending on the users preference, and a
blanking nut is provided to blank off one outlet when
being used as a 2 way valve. When using as a 3 way
valve, the thrid outlet may be used for body jets or
other accessories which are not supplied.
You should measure the distance between the outlets
on the mixer valve you are fitting to determine the
exact distance.
4. At this point you may wish to fit the pipework and
the wall arm (see wall arm fitting and wall outlet)
prior to any tiling.
5. The valve should be attached firmly between 85mm
and 95mm below the finished surface to allow the
cover plate to fit neatly, using the two fixing holes
on the valve. Position the valve centrally between
the feed pipes and mark the screw positions, drill
and plug the wall.
NOTE: Make sure the mixer valve is kept in a clean
place to prevent rubbish etc, getting into the opening
while fitting the pipework. Tiling behind the trim plate
must leave sufficient access to the valve for servicing
later.
6. Position the mixer valve onto the hot and cold water
feed pipes and tighten the compression nuts. Hold
the mixer valve in place and secure to the wall
with screws. Make sure the mixer valve hot feed
is connected to the inlet marked hot and cold inlet
marked cold. The valve will not work correctly if
connected the wrong way (Fig 3).
7. Screw the two chrome cover sleeves onto both the
control shafts (Fig 4).
