Hot Water Connection
The hot water pipe should be connected
to either of the RP¾/20 sockets marked
"OUTLET" at the top of the unit. For the
most economical operation of the water
heater, it is recommended that all hot
water lines are insulated.
Hot water pipes installed outdoors
should be insulated with UV stabilised
insulation.
Please check local regulations regarding
the use of hot water supply pipework
that is 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/NZS 3500.4
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 valve only required where local regulations demand although it is
recommended in areas where the water saturation index is above 0.40.
