municipality, your waste management service or the Enviroheat dealer where
you purchased the appliance.

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.

Supplementary heat sources
Page 12User Manual HP M3 r3 DN.docx rev 2019/03
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
rang is to be fied to the storage tank.
Where stove coils are used for supplementary heang the water must be connected
in an open vented manner. Refer to Australian Standard AS3500 for more details on
acceptable connecon soluons.

PLUMBING CONNECTIONS

Southern Cross Water Heang Pty Ltd. recommends the use of copper pipe, cerfied
to AS1432 Class C, for use in the inlet and outlet lines to the heat pump water
system.
Piping Materials
The inlet water temperature is suggestedto be between 10 - 30°C.
Outdoor water pipes and valves should be properly insulated.

A breach of this requirement may void the warranty in the event of damage caused
by excessive pressure.
Pressure & Temperature Relief Valve
1.Fit the 700 kPa/99°C (10 kW) pressure & temperature relief valve supplied in the
parts box into G¾”F tank socket;
2.Ensure that the drain line fromthe pressure and temperature relief has a

unless the pipe manufacturer has rated it for temperatures up to 99°C and a
minimum water pressure of 600kPa at these temperatures.
