This heat pump unit is designed with two-stage heating system. The first heating system uses

R410A refrigerant, which works effectively in low ambient air temperatures, with EVI technology

available for sub zero air temperatures as low -15 degrees. The second heating system uses

R134A high heat refrigerant, which can take the water temperature up to as high as 80 degrees,

designed for wall radiators. Both refrigerants are non-flammable, ozone friendly and widely

available in Australia.

The evaporator side of the second heating system is also the condensing side first heating

system so the thermal performance of the heat pump system can be greatly improved in sub

zero ambient air taking the water to high temperatures. Of course, in temperatures above zero,

the heat pump will work more efficiently with less or no need for defrosting the evaporator coil.

should be protected by an awning from snow in Alpine areas.

not blow into a prevailing wind.

Do not face the air outlet directly at a neighbour's fence.

3.Domestic Hot Water (DHW) Storage Tank and Buffer Tank Installation

3.1 The DHW and Buffer tanks may be installed inside or outside.

3.2 Both tanks must stand vertically on a concrete plinth or firm structure that will support

its weight when full of water and not lean or be prone to fall over during its service life.

3.3 The DHW tank should be installed in accordance with Australian Standard

AS/NZS3500.4 and any local or other relevant Government regulations. It is best to install

the DHW tank as close as possible to the hot water outlet that has the greatest usage,

such as the kitchen.

3.4 Some building codes require a seismic restraint. Consider using stainless steel bands

to secure the tank against the wall.

3.5 When filling the DHW tank, open the hot water taps in the laundry and kitchen to purge

air from the water lines.

3.Domestic Hot Water (DHW) Storage Tank and Buffer Tank Installation

HIGH TEMPERATURE AIR TO WATER HEAT PUMPHIGH TEMPERATURE AIR TO WATER HEAT PUMP

3.6 When filling the Buffer Tank, use pure rain water with mould inhibitor, add Glycol if prone

to freezing conditions, and water pH should ideally be at 7.0.

3.7 An expansion tank must be included in the hydronic closed loop to allow the heated

water to expand.

5.1 Water pipe material should be heat resistant and rust-proof. This can be stainless steel,

copper, aluminium, hot water PPR pipes, etc according to relevant standards.

5.2 The choice of pipe size should match the heat pump inlet and outlet with the pipework

of the system, and follow the relevant standards.

5.3 The hot water storage and buffer tank drain port and pressure and temperature relief

valve should be installed to allow for proper drainage according to relevant standards.

5.4 The hot water storage and buffer tank must be installed with an isolating valve to allow

for maintenance.

5.5 The water pipes should be arranged with smooth bends to reduce pressure loss in the

system.

5.6 The water inlet should be fitted with a one-way valve and isolating valve, or duo valve.

5.7 The water inlet should be fitted with a water filter (note the duo valve may have a water

filter).

5.8 The hot water outlet of the outdoor unit should be connected to the solar return port on

the storage tank.

5.9 The air-conditioning side buffer tank should be installed in series on the outlet of the

main pipe.

5.10 After the water flow and return pipes are connected to the hot water side and

air-conditioning side, the system should be tested at water supply pressure for 24 hours to

ensure that the system does not leak. Then insulate relevant hot water and air-conditioning

pipes, and plumbing fittings.

5.11 In order to discharge all air from the water pipeline, the water supply return pipe should

have an automatic exhaust valve installed at the highest point.

5.12 An expansion tank and automatic stop valve should be installed into the water system,

and located indoors in areas with sub zero temperatures to prevent possible cracking of the

water pipes and valves when not in use in the winter.

5.13 The water flow and return lines to the outdoor unit should have a thermometer and

water pressure gauge installed to enable monitoring of key operational parameters.

5.Pipe connections

4. Installation of indoor heating and cooling equipment

5.1 Indoor heating and cooling equipment such as fan coils, radiator heating or floor

heating, should be installed in accordance with relevant regulatory requirements,

engineering design drawings, and the manufacturer's installation instructions.

5.2 Use soft connectors to connect the outdoor unit and indoor heating and cooling

equipment.

5.3 Install condensate water drain pipes to the indoor fan coil units with smooth drainage

lines for the condensate water to flow easily.

6.2 Next, pull the pin out and check that the position of mark is at the same level as the inlet

of the temperature detector and check whether the sensor is inserted into the pipe terminal.

6.3 Finally, seal the inlet of the temperature detector with silicone.

The water pipes should be subjected to a pressure test before operation of the water

system.

The water system allows for water pressure range: 200 - 700kPa.

The outdoor unit allows for water temperature range: 5-80 C.

Water should drain from the pressure and temperature relief valve to a drainage pipe.

The pressure and temperature relief valve should be periodically exercised by gently

pulling the lever up. This will help to remove possible accumulation of calcium carbonate,

and ensure that the valve is working properly.

Install one-way valves, filters, pressure and temperature relief valves, and any other

plumbing fittings consistently with the marked flow direction and in accord with relevant

standards.
