General installation
This fitting is a mixing device and therefore water supplies should be reasonably
balanced.
When installed, the fitting must comply with the requirements of the Water Supply
(Water Fittings) Regulations 1999 and Scottish Byelaws 2004. Please check with your
local water undertaker if there is any uncertainty.
Before making any inlet pipe connections, all supply pipes MUST be thoroughly flushed
to remove debris. Failure to do so could result in damage or low flow from the mixer
unit. Water Supply (Water Fittings) Regulations 1999 Schedule 2 Section 13.
The fitting of isolating valves to the inlet feeds is advised for ease of maintenance.
Please take great care when installing this mixer not to damage its surface.
Please note if installing in an enclosed environment, access should be left for servicing
and maintenance. No costs relating to inadequate access can be accepted.

Installation
Prepare the wall with 2 copper pipes
at 147-153mm centres. Make sure the
pipes are level (Fig. 1).
Connect the water supply to the
inlet pipes. The hot water should be
connected to the left hand pipe .
Before installing your new mixer,
flush through the pipe work to ensure
removal of debris, turn off the water
supply. (Do not allow dirt, metal
particles or shavings to block the filters
fitted on inlets).
Temporarily place the valve over the
copper pipes and mark the back of the
body against the wall.
There is a small amount of adjustment
on the inlet pipes to allow fitting onto
the copper pipes. Screw each side
in or out as required, ensuring that
both sides are screwed in equally &
within the tolerance specified on the
dimension page.
Remove the valve (Fig. 2).
Remove the mounting plate from the
back of the valve by releasing the two
grub screws and pulling out the plate.
Place the mounting plate in the centre
of the marked position and mark the
two fixing holes.
Drill the marked holes to a suitable
depth for the wall plugs and secure
with supplied screws (Fig. 3).
If you are fitting the valve to a partition
wall or a wall of particularly soft
substrate you will need specialist fixings.

plated surfaces.
Place the covers over the copper pipes, followed by the nuts and the olives.
Push the valve onto the copper pipes and the mounting plate, tighten both the nuts
on the inlets being careful not to damage the plated surface.

Commissioning
The valve has been factory set under
balance pressures and hot water supply
at 65°C.
When your specific operating conditions
are significantly different from above, the
temperature of the water may vary from the
setting.
When the difference is too great, you can
adjust the calibration of the valve to suit
individual requirements of the installation:
1. Check the temperature of the water
being delivered from the outlet with a
thermometer, when the temperature control
handle is located at 6 o’clock.
Note: temperature readings should be taken
at normal flow rate after allowing for the
system to stabilise.
2. If the temperature is not 38°C proceed to
reset the calibration as follows:
Remove the temperature control handle
(see fig.1)
Ensure the step on the stop ring is located at
4 o’clock (see fig.2).
Do not remove the stop ring. Turn the spline
of the thermostatic valve clockwise to
decrease the temperature and anti-clockwise
to increase the temperature until 38°C is
achieved at outlet.
Note: the sensing part of the thermometer
probe must be fully submerged in the water
that is to be tested.
Replace the temperature control handle
ensuring that the lever is located at 6 o’clock
(see fig.3).
With the handle attached ensure the
temperature does not exceed 42°C when
turned anti-clockwise to the fully hot
position (see fig.4).
Your valve setting is now commissioned.
