the cavity to enable any slack to be
accommodated.
At this point it is advised to fit a blanking plug
in the fixed head female fitting prior to leak
testing.
Leak testing
Ensure the on/off flow control spindle is in the
off position by temporarily fitting the on/off
flow lever and turning clockwise until resistance
is felt. Open the supplies and test for leaks in all
pipework upstream of the valve.
Turn on the on/off flow lever and test for leaks
up to the fixed head outlet. Remedy any leaks if
necessary. Turn off the water supplies.
Making good
Fit the supplied tiling shroud over the mixer
body and make good the wall, tiling etc. up to
the fixed head outlet.
Plaster or tile up to the edge of the shroud.
Note that if the tiles are accurately cut to match
the profile of the shroud, then the face plate
will seal around the hole in the tiles, and the
valve unit will be able to be serviced without
the need to break any tiles.
Ensure the grout lines are flush with the tiles in
order to provide a smooth sealing surface for
the face plate.
FITTING THE FIXED HEAD
Screw in place the showerhead arm and mark
the position of the three fixing holes
(fig.9)
.
Drill and plug the holes using the plugs
supplied.
NOTE:
If fitting to a hollow wall structure, use
suitable cavity wall fittings.
Apply PTFE tape to the 1/2” BSP thread on the
shower head arm before fitting.
Secure the showerhead arm to the wall with the
three screws supplied
(fig.10)
.
Screw the ball swivel and locking ring onto the
end of the showerhead arm
(fig.11)
ensuring
the ‘O’ ring is in place.
NOTE:
The ball swivel must be screwed on
tight in order to provide a water tight
connection. The use of an appropriate tool may
be used if necessary.
