General installation
Thermostatic Valves
This mixer valve is suitable for any water system. Where instantaneous heaters are used,
the flow of hot water sufficient to start and go on burning must reach the minimum
flow required – as specified by the heater manufacturer.
These fittings 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 fitted 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
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 4 G13.1
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.
Operating pressures (on hot and cold line) should be kept as balanced as possible in
order to assure optimum efficiency.
Note: When pressure is higher than 5 bar a pressure reducer is required to be fitted
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.
Care of the mixer
Our products are finished to the highest standard and due care needs to be taken to
ensure their looks are retained.
We recommend cleaning all products with a soft damp cloth ONLY and advise strongly
against the use of ALL cleaning products i.e. powders and liquids.
If the above instructions are not followed this will invalidate your guarantee in the
event of a problem occurring.
Maintenance - continued
This thermostatic valve is fitted with a double filtering facility. Filters are fitted on the
water inlets and on the thermostatic cartridge.
Depending on the water quality, filters may become dirty, causing reduced flow and
inefficient working of the valve.
Shut off the water supply to both inlets at the isolating valves.
Inlet Filters.
Undo both locking nuts at the back of the valve and remove from the wall. Pull out
the filter/washer, rinse in water to remove the dirt, and then soak them in vinegar or
descaling agent.
Cartridge Filters
To clean the filters, you must first remove the cartridge from the housing.
Removing the Cartridge
1. Remove the handle (see temperature resetting).
2. Unscrew the grubscrew on the underside of the body and pull out the cartridge.
3. Clean the filters by rinsing them in water to remove the dirt and soaking them in
vinegar or descaling agent.
4. Before reassembling the cartridge, clean its housing with a wet cloth and grease the
‘O’ rings on the cartridge.
5. Reassemble the cartridge into the body aligning up the hole in the cartridge with
the grubscrew, then place the plastic stop ring onto the cartridge with the stop at the
12 o’clock position.
6. Make sure everything is tight and secure and turn on the water supply at the
isolating valves.
7. Now check the water temperature to ensure you are happy with it.
8. Ensure that the stop on the stop ring is at 12 o’clock and replace the handle with the
temperature override button also pointing at 12 o’clock being careful not to turn the
spline of the valve.
9. Secure the handle and replace the lever.
