Plumbing Connections
Hot Water Connection
the hot water pipe should be
connected to either of the RP¾/20
sockets with red surrounds at the
top of the water heater. For the most
economical operation of the water
heater, it is recommended that all hot
water lines are insulated. Please check
local regulations regarding the use of
hot water supply pipework that are
not made of copper.
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.
Note:
a combined isolating valve/non-return valve/line strainer may be used.
Expansion control valve only required where local regulations demand.
