Thermostatic Valves
This mixer valve is suitable for any water system, provided minimum water pressure
is met. Where instantaneous heaters are used, the ow of hot water sucient to start
and go on burning must reach the minimum ow required – as specied by the heater
manufacturer.
These ttings are mixing devices and therefore water supplies must be reasonably
balanced.
Where connections are made to the mains cold water supply, WRC approved single
check valves must be tted to both hot and cold inlets. This is a stated requirement of
Water Supply (Water Fittings) Regulations 1999 Schedule 2, Section 6 G15.13.2
Before making any inlet pipe connections, all supply pipes MUST be thoroughly
ushed to remove debris. Failure to do so could result in damage or low ow from the
mixer unit. Water Supply (Water Fittings) Regulations 1999 Schedule 2 Section 4 G13.1
The tting 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.
Operating pressures (on hot and cold line) should be kept as balanced as possible in
order to assure optimum eciency.
Note: When pressure is higher than 5 bar a pressure reducer is required to be tted
before the valve.
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.
