General installation
Important - please read
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.
For further information, contact the Water Regulations department of your local water
supplier (see the WRAS website www.wras.co.uk for details) or the Water Regulations
Advisory Scheme by email (info
@
wras.co.uk) or telephone: 01495848454.
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.

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 the 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.
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 handle.
Ensure the step on the stop ring is located at 12 o'clock.
Do not remove the plastic 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 handle making sure that the pin is against the step.
Once the handle has been attached ensure the temperature does not exceed 46°C when
turned entirely anti-clockwise.
Your valve setting is now commissioned.
