between the non return valve and the
water heater. See the diagram below for
details.
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. Please check
local regulations regarding the use of
hot water supply pipework that are not
made of copper.
Insulation of Pipes
All hot water pipes must be insulated
with UV stabilized insulation suitable
for solar working temperatures, e.g.
Armaex Insulation.
Note: a combined isolating valve/non-return valve/line strainer may be used.
Expansion valve only required where local regulations demand.

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/NZS3500.4.2
that a suitably approved temperature
control device be tted 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.
