General Installation
Operating Specifications
Important - Please Read
Operating Pressure
Minimum operating pressure 0.2 bar (1 bar if used as a bath fill)
Maximum operating pressure 5 bar
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 ([e-mail]) or telephone: [phone].
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.
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
Flush pipe work thoroughly before fitting the valve.
Warning! Please check for any hidden cables and pipes before drilling holes in
the wall.
The valve must be set into the wall between (79.5mm min – 101.5mm max).
If you are fitting the valve to a partition wall or a wall of particularly soft substrate
you will need specialist fixings.
Please contact VADO or retailer for WG-STUDFAST-C-S/S fixing.
Mortar guard
During installation please leave the mortar guard secured to the valve to avoid
damage to the product and protect the internals during tiling etc.

Temperature Commissioning
Note: mixed water temperature at terminal tting should never exceed 46°C.
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, when the stop arm is located at 12 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 stop adaptor.
Ensure the step on the stop ring is located at 8 o'clock.
Do not remove the plastic stop ring.
Please continue on next page.

Screw
Temperature Commissioning
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 stop adaptor making sure that the stop arm is located at 12 o’clock.
When the handle is attached (see page 13) ensure the temperature does not exceed
46°C when turned entirely anti-clockwise.
Your valve setting is now commissioned.
