Avon thermostatic mixer shower
7
INSTALLATION
a) General conditions
NOTE: The outlet of the shower must not be
connected to anything other than the
sprayhead supplied.
DO NOT use jointing compounds on any pipe
fittings for the installation.
Suitable 3/4”BSP to 22mm or 15mm
compression fittings (not supplied) must be
used for connecting to the water supplies.
DO NOT solder fittings within the vicinity of the
mixer unit as heat transfer can damage the seals
and thermostatic components.
NOTE: Suitable service valves (complying with
Water Regulations and Byelaws) MUST be fitted
on the hot and cold water supplies to the
shower as an independent means of isolating
the water supplies should maintenance or
servicing be necessary
When connecting the pipework, avoid using
tight 90°elbows. Swept or formed bends will
ensure optimum performance.
The hot water inlet is stamped ‘HOT’and the
cold water inlet is identified ‘COLD’.
3/4”BSP straight or elbow male thread
couplers must be fitted to the inlet ports for
either rising, rear or falling hot and cold water
supplies.
A 3/4”BSP straight coupler needs to be fitted
to the valve outlet.
NOTE: These couplers are NOT supplied.
Screw the couplers into the inlets and the outlet
of the valve. THE COUPLERS MUST BE
TIGHTENED AGAINST THE VALVE BODY. The
fittings will require PTFE tape or other means of
sealing.
Before starting, ensure the available depth of
recess or cavity is between 65 - 80mm
measured from the finished surface.
The allowance for varying thickness of tiles up
to 10mm is accommodated by a limited degree
by the tolerance between the control knob and
trim ring.
b) Installation in a solid wall
Decide on the shower position and determine
whether the hot and cold water supplies will
enter the shower from the top (falling) or
bottom (rising) or rear.
The building depth should be at least 65mm
deep from the finished wall surface.
As a guide for the size of hole, it should be
sufficient to accept the valve complete with the
inlet and outlet fittings and also allowing access
for connection to the pipework (fig.7).
Remove the plaster and brickwork to the
required depth and chase out any additional
areas of the wall to facilitate pipework to and
from the valve. Note that the valve body
requires a deeper recess (approximately 5mm
greater) than the inlet and outlet fittings.
Offer the valve body up to the wall and mark
the two fixing holes. Remove the valve and drill
and plug the wall. Route the pipework to valve
body position.
Flush out the pipework in accordance
with Water Regulations and Byelaws.
Offer the valve up to the pipework and secure
with screws through the two fixing brackets on
the valve body.
Proceed to ‘connecting supply pipes’section.
c) Installation in a hollow wall
Decide on the shower position and determine
whether the hot and cold water supplies will
enter the shower from the top (falling) or
bottom (rising) or rear.
When installing into a stud partition or other
hollow wall structures, the installer will need to
consider fabricating rear supports or other
options. Such options are beyond the scope of
this guide.
The hollow cavity should be at least 65mm
deep from the surface of the wall.
Mark the route of the incoming and outgoing
pipework.
Take out the plasterboard. Offer the valve body
up to the fabrication and mark the two fixing
holes. Remove the valve and drill the holes.
Route the pipework to the valve position.
