13 INTEGRAL ISOLATION VALVES
The integral isolation valves facilitate a number of activities:
• Servicing the thermostatic cartridge
• Audit Cold Water Isolation (CWI) test
• Demounting the mixer from its inlets
To isolate the mixers, proceed as follows:
1. Unscrew the wall shrouds and slide forward
2. Isolate both inlets by screwing isolation valves down fully using a 5mm Allen key in the
