Page 11: Operation
OPERATION & SENSOR ADJUSTMENT Operation Both mixers are operated when the user places a hand in the detection zone. With the proximity version, flow starts when a hand is placed in the detection zone and will continue until it is removed. The other version gives a timed flow which is started by placing a hand in the detection zone. -

This updated design permits quick & easy removal of the mixer for cleaning, disinfection & maintenance purposes.
- Page 18 Protective cover caps If a replacement mixer is not available, a pair of protective cover caps should be fitted to the inlets. For product code see section 18. For both practical and functional reasons along with environmental contamination reasons, the inlets should not be left open.

- Page 22 INTEGRAL THERMAL-DISINFECTION This fitting is equipped with a disinfecting feature, which allows an engineer to feed water from the hot inlet via a temporary by-pass hose* into the cold inlet. This hot water then passes through the cold inlet, the thermostatic mixing chamber and out through the mixed water outlet. The temporary bypass hose is inserted into special valve connectors in the inlet tails normally concealed by the shrouds.
