Temperature Protection
Water heaters can produce very hot
water. to reduce the risk of scald
injury, it is mandatory under the
requirements of australian standard
as/nZs3500.4 that a suitably
approved temperature control device
be fitted to the hot water supply to
outlets used primarily for personal
hygiene. this valve should be checked
at regular intervals to ensure its
operation and settings remain correct.
