NOTE: Valves o erating outside these conditions cannot be guaranteed by the
Scheme to o erate as Ty e 3 valves.
Hot and cold su ly ressures should be ke t 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 oint of discharge is 41°C
When ressures exceed 5 bar, a ressure reducing valve must be fitted (not
su lied) before the valve assembly.
If a water su ly is fed by gravity then the su ly ressure should be verified to
ensure the conditions of use are a ro riate for the valve.

Through years of use, im urities and lime scale could build u on the filters in the elbows
which could affect the erformance of the roduct, you should then remove the filters and
clean.
To do this, first turn off the water su ly to the valve, then remove the grub screws (1) from
the valve body (2) using the allen key rovided.
Disconnect the valve (2) from the nuts (1) and remove valve, ensure that you take a firm

The urchased roduct is a thermostatic sequential ex osed shower valve.
The shower has a single lever which allows both control of tem erature and flow.
The cold water is obtained by turning the lever from the OFF osition anti-clockwise.
(NOTE: The tem erature of the cold water de ends on the system and the re-set
tem erature of the shower).
By turning the lever both flow and tem erature will increase.
The maximum tem erature has been re-set under factory conditions at a rox 45°c,
this can be adjusted by following the instructions shown in the section headed
“CALIBRATION”
Subject to correct installation, this mixer is suitable for any water system, in case of
instantaneous heaters, hot water flow must meet at last the minimum flow required by
the heater.

The water su lies are connected to the mixer via two elbows, which include
com ression nuts and olives to suit 15mm su ly i es.
The tem erature setting has been carried out under factory conditions and in
accordance with BS EN1111.
The shower will be received with the outlet to the bottom and the hot inlet (red sticker)
to the left), if you require a to outlet, do not sim ly turn the valve over, you must
change the location of the blanking lug and outlet.
Remove the blanking lug using a wide blade screw driver and remove the outlet using
a 12mm allen key.
Once removed swa the lug and outlet and re-fit and tighten fully .

Once installed the tem erature settings can be adjusted, but note this roduct is a
sequential mixer and therefore if the maximum outlet tem erature is increased the
minimum tem erature will also increase.
Turn the shower to fully hot and then turn off the water su ly to the valve.
Remove the lever arm (2) and grub screw (1) from head section (3)
Remove grub screw (1) from inside the head section (2) , using the allen key rovided.
You must then slightly loosen the nut (1) using a 13mm s anner, insert the allen key
inside the nut and turn the grub screw, turn it anti-clockwise to increase the
tem erature.
O nce the desired tem erature is reached, carry out this
instruction in reverse to re-assemble

Before installing the valve, if there is a variation in ressure between hot and cold, the
su lied regulators can be used in the elbow (3) to reduce the higher ressure, to do
this, insert the regulator (2) into the elbow, followed by the brass retaining ring (1)
