Remove the gripper ring assembly from the rear of the back plate and ensuring
correct alignment of the gripper rings, slide over the projecting pipes flush to the wall

If the valve is being installed for use with a gas fired instantaneous (multipoint) water
heater or a combination boiler, the cold water flow regulator must be fitted at this
stage by insertion into the cold water port.
(The flow regulator is supplied in its own pack).
Remove the four cartridge fixing screws and carefully detach the cartridge assembly
from the back plate. Fit the flow regulator into the cold port fully home, with the
central O’ ring facing the incoming flow. A small length of 15mm pipe may used to facilitate the
installation of this regulator. Refit the cartridge to the back plate using the four fixing screws ensuring
the hot and cold markings on the cartridge are uppermost.

Run a thin bead of silicone sealant in the mastic groove of
the back plate. Using a silicone based lubricant, lubricate
the projecting pipe ends before carefully pushing the
shower valve into position fully home. Secure using the
screws provided.
