accordance with:

• AS/NZS3500.4.2 “National
Plumbing and Drainage Code Hot
Water Supply Systems – Acceptable
Solutions”.

• AS/NZS3000.

• Local authority regulations.

• Outside Australia and New Zealand,
please refer to local plumbing and
building codes and regulations.

• Notice to Victorian customers from
the Victorian Plumbing Industry
Commission – this water heater
must be installed by a licensed
person as required by the Victorian
Building Act (1993). Only a licensed
person will give you a compliance
certicate, showing that the work
complies with all the relevant
Standards. Only a licensed person
will have insurance protecting their
workmanship for 6 years. Make sure
you use a licensed person to install
this water heater and ask for your
Compliance Certicate.

Water Supply Pressure

This water heater is designed for direct
connection to water supply pressures of:

80 Litre model – 1120kPa

125 Litre model – 1120kPa

160 Litre model – 1120kPa

250 Litre model – 800kPa

315 Litre model – 800kPa

400 Litre model – 800kPa

Where the mains pressure can exceed
or uctuate beyond the pressure
shown above, a pressure limiting
device (complying with AS1357) must
be tted in the cold water inlet supply.
This device must be installed after
the isolating valve and set below the
pressure shown above. Note that
during periods of lower demand, water
pressure may increase.

Caution: This water heater delivers
hot water at temperatures exceeding
50°C. Refer to AS/NZS3500 and
local regulations regarding the need
for additional hot water delivery
temperature control.

Pool Heating

This water heater must not be used for
pool heating.

Installation Details

Location

The water heater should be located as
close as possible to the most frequently
used hot water outlet. Adequate
access must be made for service to the
element(s), thermostat, relief valve and
anode. Ensure that the data plate is
clearly visible.

Note: All models are equipped with a
sacricial anode, accessible through the
top cover. Allow 50% of the height of
the water heater for clearance above to
replace the anode.

We recommend a plinth be installed
under the water heater where the
water heater is subjected to wet
conditions.

A properly drained overow tray must
be used where property damage could
occur from water spillage. (See AS/
NZS3500.4.2 for further details.)

When installing this water heater in a
roof area as a mains pressure unit, refer
to local regulations.

Note: The warranty does not cover
damage due to leakage of the water
heater.

Plumbing Connections

Pressure & Temperature Relief
Valve

The Pressure & Temperature Relief Valve
is supplied loose with the water heater.
The valve rating is:

80L = 1400 kPa
125L = 1400 kPa
160L = 1400 kPa
250L = 1000 kPa
315L = 1000 kPa
400L = 1000 kPa

The PTR valve must be installed directly
into the top socket marked “RELIEF
VALVE”. The drain line from this valve
must run in a continuously downward
direction in a frost-free ambient position
with the discharge end left open to
atmosphere permanently.

The PTR Valve is not intended to enable
connection of the water heater to
supplementary energy sources such as
solar panels or slow combustion stoves
(refer AS/NZS 3500.4 for guidance on
these types of installations).

Open the PTR Valve for approximately
10 seconds by lifting the lever on the
valve to ensure water is relieved to waste
through the relief drain pipe. Lower lever
gently and check that it closes correctly.

The PTR Valve must not be tampered
with or removed. The water heater must
not be operated unless this valve is
tted and in working order.

The PTR Valve should be checked for
adequate performance or replaced at

intervals not exceeding 5 years, or less
in areas where local regulations apply.

Important: The PTR Valve and its
drain outlet pipe must not be sealed or
blocked. It is normal for the PTR valve
to leak a small amount of water during
heating cycles.

Danger

Failure to operate the relief valve easing
lever at least once every six (6) months
may result in a problem with the water
heater and in some cases the tank may
explode.

Warning: A separate drain line must be
run for this relief valve. It is not permitted
to couple drain lines from relief valves
into a single common drain line.

Note: Brass plugs are supplied with
the water heater to plug off the unused
ttings. Ensure that a sealing material is
applied to the plugs to prevent leaking.

Cold Water Connection

An approved isolating valve, non
return valve, line strainer (optional but
recommended), and union must be
tted between the supply main and
either of the RP¾/20 sockets marked
“Inlet” at the bottom of the water heater.
All ttings must be approved by the
relevant Authority. See the diagram on
page 5 for details.

Note for S.A. and W.A.: It is a state
requirement that a pressure relief valve
be tted on the cold water supply line
