INTRODUCTION
This thermostatic mixer with wave on / wave off sensor is manufactured to the highest standards and has
approval to AS4032.4 which permits it to be installed in healthcare establishments such as hospitals, nursing
homes and residential care homes. When installed in healthcare establishments the supply conditions
detailed in Table 2 must be observed and the commissioning and servicing requirements detailed on section
8.0
must be followed.
5.2
SUPPLY PRESSURE REQUIREMENTS
This mixer is designed to be installed on all types of plumbing systems. Hot and cold water supply pressures
should be reasonably balanced; however, the mixer will function within specification on unequal pressures up
to 10:1. The mixer has integral isolating valves which permit servicing of the strainer, check valve/flow
regulator and thermostatic cartridge. They are also used for thermal disinfection. The minimum pressure for
the correct thermal operation is 30kPa. However, to achieve an acceptable flow performance at very low
pressures it may be necessary to remove the combined check valve and flow regulators and replace them with
simple check valves to facilitate thermal disinfection.
