Maintenance
This thermostatic valve is fitted with filters, these are located on the thermostatic cartridge.
Depending on the water quality, filters may become dirty, causing reduced flow and
inefficient working of the valve.
To clean the filters, you must first remove the cartridge from the housing.
Please note,
when maintenance is carried out on the CD cartridge, the double ‘O’
rings on the spline will need to be removed prior to detaching the handle. Once the
cartridge and spline has been placed back into the body, replace the handle before
locating the ‘O’ rings to their original position.
Removing the Cartridge
1. Shut off the water supply to both inlets at the isolating valves.
2. Remove the handle by pulling out the screw cover, remove the screw from inside
(cross head on round and Hexagonal head on square).
3. Pull out the stop ring from the body.
4. Using a suitable spanner unscrew and remove the cartridge.
5. Clean the filters by rinsing them in water to remove the dirt and soaking them in
vinegar or descaling agent.
6. Before reassembling the cartridge, clean its housing with a wet cloth and grease the
‘O’ rings on the cartridge.
7. Push the cartridge into the body and tighten, push in the stop ring with the stop at
the front position.
8. Make sure everything is tight and secure and turn on the water supply at the
isolating valves.
9. Now check the water temperature to ensure you are happy with it.
10. With the temperature override button at the front, push in the button and push the
handle down onto the splines, being careful not to turn the splines of the valve.
11. Secure the handle.

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.
