Installer’s Guide

Full and detailed installation instructions

are in the Installer’s Guide, included

inside the water heater’s carton.

Outdoor Tank Installation

The water heater must be installed

outdoors, with the minimum clearances

as shown in the gure below.

We recommend a plinth be installed

under the water heater where the

water heater is subjected to wet

conditions. Please refer to AS/NZS

3500.4, clause 5.5.3.

Minimum clearance around the windows

and doors must be maintained – refer to

AS 5601.

Location

The water heater should be located as

close as possible to the most frequently

used hot water outlet. Ensure that the

data label is clearly visible and that there

is adequate access for servicing the unit.

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.

A properly drained overow tray must

be used where property damage could

occur from water spillage. (See AS/

NZS3500.4 for further details). Warranty

does not cover consequential damage

due to heater leakage.

Safety

This appliance is not intended for use

by persons (including children) with

reduced physical, sensory or mental

capabilities, or lack of experience and

knowledge, unless they have been given

supervision or instruction concerning

use of the appliance by a person

responsible for their safety.

Children and animals should be

supervised to ensure that they do not

interfere with the appliance.

Frost Protection

The areas in gray in the map below may

be vulnerable to frost. Solar hot water

heaters installed in these areas require

an approved antifrost protection device

to maximise system performance.

Note: The Gas Boosted Solar water

heater already has an in-built frost

protection device, so no further antifrost

protection is required.

Installation Requirements

This water heater must be installed

by a licensed tradesperson, and in

accordance with:

• AS/NZS3500.4 “National Plumbing

and Drainage Code Hot Water

Supply Systems – Acceptable

Solutions”.

• AS5601/AG601 “Gas Installations”

• 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 and only a

licensed person will have insurance

protecting their workmanship for 6

years.

Water Supply Pressure

This water heater is designed for direct

connection to water supply pressures of

no greater than:

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 during

periods of lower demand water pressure

may increase.

Pool Heating

This water heater must not be used for

pool heating.

Pressure & Temperature Relief

Valve

The Pressure & Temperature Relief (PTR)

Valve is supplied loose with the water

heater. The valve rating is:

1000kPa

The specications and part numbers of

the PTR Valve provided are:

Part No: H0443

Description: PT VALVE ½" – HT55

1000kPa

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.

Warning: We recommend that you

open the PTR valve at least once every

six (6) months. Failure to do this may

result in problems with the water heater.

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.

Cold Water Connection

It is mandatory to t the following items

between the supply main and the

RP¾"/20mm socket in the water heater.

• an isolating valve

• a non return valve

• a line strainer

• a union

All ttings must be approved by the

relevant Authority and in accordance to

the plumbing code.

Note: a combined isolating valve/non-

regulations demand.

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

between the non return valve and the

water heater.

Hot Water Connection

The hot water line should be connected

to the “OUTLET” socket on the tank.

Insulation of Pipes

All hot water pipes must be insulated

with UV stabilized insulation suitable

for solar working temperatures, e.g.

Armaex Insulation.

Building Flow & Return

Never install a building circulated ow

and return line to the inlet connection

of a Dux (Electric solar or Gas solar

hot water heater) or (Heat Pump water

heater)

The solar water heater is not designed

to be installed on a circulated ow

and return line due to loss of thermal

efciency. Extensive pipe work will

cause efciency losses gained from

solar energy and will increase energy

consumption.

If a ow and return line is required, we

recommend that you install a backup

storage or continuous ow water heater

on the ow and return line and a time

control the building circulation loop to

help reduce energy usage.

Temperature Protection

All solar water heaters have the ability

to produce hot water very quickly.

To reduce the risk of scald injury, it is

mandatory under the requirements of

Australian Standard AS/NZS3500.4 that

a suitably approved temperature control

device, such as a tempering valve, be

tted to the hot water supply to outlets

used primarily for personal hygiene.

Note: This water heater is supplied

with a tempering valve. Install the

valve according to the manufacturer’s

recommendations. Any adustments to

the valve should be made according to

the manufacturer’s recommendations.

The tempering valve should be checked

at regular intervals to ensure its

operation and settings remain correct.
