NOTE: Valves operating outside these conditions cannot be guaranteed by the
Scheme to operate as Type 3 valves.
Hot and cold supply pressures should be kept balanced in order to obtain maximum
efficiency.
The valves designation of use is for High Pressure Shower (HP-S) BS EN 1111 and
the recommended mixed water outlet for showers at point of discharge is 41°C
When pressures exceed 5 bar, a pressure reducing valve must be fitted (not
supplied) before the valve assembly.
If a water supply is fed by gravity then the supply pressure should be verified to
ensure the conditions of use are appropriate for the valve.

Cleaning or replacing elbow filters
Through years of use, impurities and lime scale could build up on the filters in the elbows
which could affect the performance of the product, you should then remove the filters and
clean.
To do this, first turn off the water supply to the valve, then remove the grub screws (1) from
the valve body (2) using the allen key provided.
Disconnect the valve (2) from the nuts (1) and remove valve, ensure that you take a firm
hold of the valve body to prevent it from falling into the shower/bath.
Remove the filters (1) from inside the elbows (2) and carry out maintenance, to clean hold
under running water.
