Isolation procedure
IMPORTANT: Please see the below procedure for isolating this
thermostatic valve.
1. Remove handles/faceplate and trim parts allowing access to
the isolation points on the valve.
2. Screw down the isolation screws clockwise until you feel a
resistance (taking care not to over tighten).
3. Turn shower on to check isolation, please ensure that
your body/hands are not under the flow of water as there is a
potential for delivery of hot water.
4. Remove temperature stop ring (essential).
5. With shower in the on position, replace temperature handle
on thermostatic valve (ensure temperature stop ring has been
removed).
6. Turn temp handle fully anti clockwise until stop point is
reached and can be turned no further, please ensure that your
body/hands are not under the flow of water as there is potential
for delivery of hot water if isolation has been unsuccessful.
7. Turn temperature handle fully clockwise until resistance is
felt.
8. If there is no flow of water coming from the outlet during
both points 6 and 7 isolation has been successful, you may now
remove and maintain the cartridge.

isolate at an alternative point within the system for both hot and
cold and repeat points 3-9.
