CONNECTIONS – PLUMBING
An isolation valve and non-return valve must be installed on the cold water line to the water heater. An
acceptable arrangement is shown in the diagram on page 45. Refer also to
"Mains Water Supply"
and to
and hot water outlets are shown on page 46. The solar hot and solar cold pipe connections are shown on
page 48.
A disconnection union must always be provided at the cold water
inlet, tempered water and hot water outlets on the solar storage
tank to allow for disconnection of the solar storage tank. It is
necessary to remove the brass plug from the hot water outlet fitting
if a hot water line is to be installed. This plug can be used to plug
the tempered water outlet if a tempered water line is not being
installed. Refer to the diagram for the connection points to the
water heater.
Insulation used on the tempered water and hot water lines must
extend up to the outlets of the water heater. The valve and fittings
must also be insulated up to the hot water outlet of the gas booster.
This solar storage tank has either a plastic dip tube or fitting liner
in the inlet and outlet fittings (see diagram). These must be in place
for the water heater to function properly. Do not remove or damage
them by using heat nearby. They will be pushed into the correct
position as the fitting is screwed in.
Note: The solar storage tank of a solar water heater should not be
installed as part of a circulated hot water flow and return system in
a building. The benefits of solar gain will be significantly reduced.
If a circulated flow and return system is required, it is necessary to
connect the return line to the in-series booster, not the solar
"Circulated Hot Water Flow and Return
storage tank. Refer to
System"
on page 29.
This water heater is intended to be permanently connected to the
water mains and not connected by a hose-set. A braided flexible
hose or semi-flexible connector may be used for connection to the
water heater, where permitted by AS/NZS 3500.4.
PIPE SIZES
To achieve true mains pressure operation, the cold water line to the water heater should be the same size or
bigger than the tempered water and hot water lines from the water heater. The minimum recommended
tempered pipe and hot pipe sizes are DN20.
The pipe sizing for hot water supply systems should be carried out by persons competent to do so, choosing
the most suitable pipe size for each individual application. Reference to the technical specifications of the water
heater and local regulatory authority requirements must be made.
TEMPERATURE PRESSURE RELIEF VALVE
The temperature pressure relief valve is shipped behind the lower front cover of the water heater. The
temperature pressure relief valve must be fitted before the water heater is operated. Before fitting the relief
valve, make sure the probe has not been bent.
To fit the relief valve:

Seal the thread with an approved thread sealant such as Teflon tape - never hemp. Make sure tape does
not hang over the end of the thread.
 Hand tighten the valve into the opening marked "Relief Valve" (refer to the
page 32).
