CONNECTIONS – PLUMBING
All plumbing work must be carried out by a qualified person and in accordance with the requirements of
Standards AS/NZS 3500.4 or AS/NZS 3500.5:2012 Section 3 (for a Class 1a or Class 10 building) as
applicable under the Plumbing Code of Australia, and all local codes and regulatory authority requirements.
Warning: Certain types of plastic pipe, such as polybutylene pipe, are not suitable to be used as a hot
water pipe between:

this water heater and a temperature limiting device, and

this water heater and a hot water outlet if a temperature limiting device is not installed.
This water heater can produce water at a temperature and pressure which can exceed the performance limits
of these types of pipe. This may result in pipe failure leading to severe water damage to the property. If one of
these types of plastic pipe is used as a hot water pipe in the property, then a temperature limiting device must
be installed between the water heater and this pipe work.
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 and energy gained
from the sun lost through the pipe work. If a circulated flow and return system is required, refer to
“Circulated
Hot Water Flow and Return System”
on page 22.
CONNECTION SIZES

Hot water connection: G 1/2 M olive tank connection: Rp 3/4

Cold water connection: G 1/2 M olive tank connection: Rp 3/4

Relief valve connection: Rp 1/2
WATER INLET AND OUTLET
All pipe work must be cleared of foreign matter before connection and purged before attempting to operate the
water heater. All olive compression fittings must use brass or copper olives. Use thread sealing tape or
approved thread sealant on all threaded joints other than those with O
’ring fittings.
An isolation valve and non-return valve must be
installed on the cold water line to the water heater. A
trio valve and expansion control valve is supplied in
the pipe kit supplied with the water heater. An
acceptable arrangement is shown in the diagram.
Refer also to
“Hot Water Delivery”
on page 21 and to
“Mains Water Supply”
on page 20.
The cold water isolation valve and expansion control
valve, if one is installed, must be accessible from
ground or floor level. They must not be installed
either on the roof or in the ceiling space, unless it is
an accessible trafficable area. Extend the cold water
line to the cold water inlet fitting on the shoulder of
the solar cold pipe.
A disconnection union must always be provided at the cold water
connection and hot water Tee at the hot water on the water heater to
allow for disconnection of the water heater.
This water heater 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.
