FUNCTION &PRINCIPLE OF OPERATION
A low-pressure liquid refrigerant is vaporized in the heat pump's evaporator and passed into
the compressor. As the pressure of the refrigerant increases, so does its temperature. The
heated refrigerant runs through a condenser coil within the storage tank, transferring heat to
the water stored there. As the refrigerant delivers its heat to the water, it cools and
condenses, and then passes through an expansion valve where the pressure is reduced and
the cycle starts over.

① Solar or boiler sensor: Used to sense the temperature of inlet heat exchanger coils.
② Boiler signal wire: It is used to provide switching signals to the boiler. This signal can start
or stop the boiler's power supply.
③Off-peak power signal wire: It is used to receive off-peak power signal from electric
power supply company. This signal can start or stop the heat pump's power supply (if
you have selected ECO mode).
④Power cable: It is used to provide power to the heat pump water heaters.

INSTALLATION INTRODUCTION
Precautions
•Do not install the water heater in the position where exposed to gas,
vapours or dust.
•Install the appliance on a flat, solid surface. The surface can support
the machine weight and the condensate water can be drained freely.
•Ensure that noise due to the operation and air flow of the heat pump
complies with the relevant regulations.
•Ensure that there is adequate ventilation around the water heater, do
not install in an enclosed space.
•Make sure there is sufficient space left for installation and
maintenance.
•Ensure there is no strong electromagnetic interference around that
may affect control functions.
•Ensure there is no sulphur gas or mineral oil existing at the
installation place, which may cause corrosion of the machine and the
fittings.
•Where ambient temperatures are likely to drop below 0°C ensure
that adequate freeze protection is provided.
Keep an adequate distance between the water heater and bedrooms.

Local Standards
The following standards and regulations must be taken into account when planning the
installation of the Enviroheat water heater system.
•AS/NZS 3500.4.2 National plumbing and drainage code hot water supply systems –
acceptable solutions.
•HB 263-2004 heated water systems plumbing industry commission.
•AS/NZS 3000 Electrical installations (known as the Australian/New Zealand Wiring Rules).
•Any local regulations that govern this type of installation.
•In frost prone areas
Where these instructions and any local regulations are in conflict, the local regulations shall
prevail.
Safety
Do not commence any aspect of this installation until you have satisfied yourself that all safety
issues have been addressed.
This installation should only be performed by an approved professional with suitable
experience and licenses, authorised by Southern Cross Water Heating Pty Ltd Group
Australia Pty Ltd to conduct the work.
It is imperative that installers adhere to Occupational Health and Safety Guidelines at all
times. The installer is responsible for their safety and the safety of those around them.
Water Quality
Water supply from an unfiltered water source that may be highly conductive or have a high
mineral content may void the system warranty.
Therefore, to ensure water quality guidelines are met, the following characteristics should not
be exceeded.
Water Properties
Acceptable Levels
Total hardness
200 mg/litre or ppm
Total Dissolved Solids (TDS)
600 mg/litre or ppm
Chloride
250 mg/litre or ppm
Magnesium
10 mg/litre or ppm
Sodium
150 mg/litre or ppm
pH
Min 6.5 to Max 8.5
Electrical conductivity
850 μS/cm
In areas of poor water quality, it is recommended that a softener, conditioner or similar device
be fitted to the water supply.
A breach of this condition may void the warranty in the event of damage caused by
water quality exceeding these characteristics.

User Manual HP M3 r3 DN (1) rev2019/03 Page 12
Supplementary heat sources
If a supplementary heat source is connected to the storage tank, the maximum energy input
cannot be more than 10 kW, including the electrical element. Where greater input is
required, a pressure and temperature relief valve with a higher kW rating is to be fitted to the
storage tank.
Where stove coils are used for supplementary heating the water must be connected in an
open vented manner. Refer to Australian Standard AS3500 for more details on acceptable
connection solutions.

User Manual HP M3 r3 DN (1) rev2019/03 Page 13
PLUMBING CONNECTIONS
Piping Materials
Southern Cross Water Heating Pty Ltd Group Australia recommends the use of copper pipe,
certified to AS1432 Class C, for use in the inlet and outlet lines to the heat pump water
system.
Plastic piping is not to be used for any portion of the water heater system plumbing unless the
pipe manufacturer has rated it for temperatures up to 99°C and a minimum water pressure of
600kPa at these temperatures.
Before making the final connections, rinse the inlet pipes in order not to introduce metal or
other particles into the tank.
The inlet water temperature is suggested to be between 10 - 30°C.
Outdoor water pipes and valves should be properly insulated.
Pressure Reducing Valve
Where the mains water supply pressure is likely to exceed 550 kPa at any time, a 500kPa
pressure reducing valve that complies with AS1357 must be fitted to the inlet of the hot water
system.
This is essential to safeguard the appliance and ensure correct operation.
A breach of this requirement may void the warranty in the event of damage caused by
excessive pressure.
Pressure & Temperature Relief Valve
Remember this valve can discharge very hot water, so carefully consider its location. Never
discharge onto a solid surface like concrete.
1. Fit the 700 kPa/99°C (10 kW) pressure & temperature relief valve supplied in the parts
box into the G¾” tank socket;
2. Ensure that the drain line from the pressure and temperature relief has a continuous
downslope and falls away from the valve and towards the ground level to a safe
location, terminating above the ground level. Please ensure that the drain is installed
in a place where it cannot be affected by freezing conditions (per AS3500).
Cold Water Expansion Relief Valve
Fit the 600 kPa pressure relief valve in the cold water supply pipe after the check valve, stop
cock and (if required) pressure limiting valve.

User Manual HP M3 r3 DN (1) rev2019/03 Page 14
Important safety information
All water heaters have the ability to produce hot water very quickly. To reduce the risk of
scald injury it is recommended that a temperature control valve be fitted to the hot water
supply pipe work. This valve should be checked every 6 months to ensure its operation and
settings remain correct.
Check that the pressure & temperature relief valve drain pipe is not located where it can
cause damage if hot water is discharged.
This water heater is not intended for use by young children, infirm persons, or persons
lacking relevant skill or experience, without suitable supervision.
Children should be supervised to ensure they do not play with hot water taps or the
water heater.
If the hot water system is not used for two weeks or more, a quantity of hydrogen gas, which
is highly flammable, may accumulate in the water heater. To dissipate this gas safely, it is
recommended that a hot tap be turned on for several minutes at a sink, basin or bath but not
a dishwasher, clothes washer, or other appliance. During this procedure there must be no
smoking, open flame or any other electrical appliance operating nearby. If hydrogen is
discharged through the tap, it will probably make an unusual noise as with air escaping. Do
not place hands or any part of your body beneath the tap during this procedure.
