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.

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

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.

7.Electrical wiring
7.1 The outdoor unit should use dedicated power supply and power supply voltage line
corresponding with rated voltage.
7.2 The power cable of the outdoor unit must support the maximum starting current
requirements.
7.3 The outdoor unit power supply circuit must have a grounding wire, which should
connect with a reliable and effective external ground wire.
7.4 Wiring must be installed by qualified technicians with reference to the circuit diagram.
7.5 The layout of power lines and signal lines should be neat, rational and strong with weak
lines separated so they cannot interfere with each other.
7.6 When power lines and control lines are parallel, the wires must be placed inside an
insulating tube, with appropriate distance between the lines.
7.7 For electrical connection of the outdoor unit, take the following wiring through the wiring
hole set into the electrical box, then connect to the appropriate terminals in the electrical
box according to wiring diagram:
8.Electrical Wire Selection
8.1 The internal motor protector does not protect the compressor against all possible
conditions. Please be sure that the system is properly earthed when installed in the field.
8.2 To avoid fire, electric shock and other accidents, only use power supply voltage
indicated on the label.
8.3 To protect the power lines, they should be fixed appropriately so that they cannot
become damaged and people cannot trip over them. Pay particular attention to the
positioning and operation of electrical plugs, which should be easily plugged into the
socket.
8.4 Do not overload wall plugs or the power cable line. Overloading may cause fire or
electric shock.
8.5 Check to ensure your electrical socket is appropriate for the power load and is properly
grounded.

9.1 Pre-start-up checks:
· Check the whole pipe system. Ensure the water volume in the system is full and the air is
exhausted completely. Check whether the water valves are open throughout the system.
· Check the thermal insulation of the pipe work, make sure relevant pipes are appropriately
lagged.
· Check the power supply and distribution system. Check whether the power supply voltage
is normal, the power distribution accessory screws are tight, supply power complies with
the wiring diagram and outdoor unit specifications and the wiring is properly grounded.
· Check the air cooled water chiller. Make sure all screws are tight. Check that the signal
indicator light (green) of the outdoor unit control panel is illuminated normally and the fault
indicating lamp (red) is illuminated.
· Connect pressure gauges to the suction Schrader valves in preparation for checking the
refrigerant pressure during operation. Disconnect them when testing is satisfactory.
9.2 Trial operation
· Press on/off on the remote controller, the water pump and fan should start immediately.
The compressor should start shortly after. Observe and determine if there is any abnormal
sound during operation. Stop to check the unit if there is abnormal sound. The outdoor unit
should continue to run only when there is no abnormal sound.
· Check whether the cooling system pressure is normal.
· Check whether the input power and current of the unit are within the parameters set out
in this manual. If not, stop the outdoor unit and check it.
· Observe whether the outlet water temperature is normal.
