1. Heat Pump Outdoor Unit installation position
Install the heat pump outdoor unit with good air flow both into and out from the unit. Ensure there is
sufficient space around the unit for maintenance and good operation, refer to the schematics and
points below:
Wrong Right
II. Installation
!Notice:
1. To get enough air for ventilation of the unit, the installation position should have good
air flow.
2. The position should not reflect noise from the air outlet or transfer vibration.
3. Protection from direct sunlight is advisable.
4. The water from rain and defrosting can be discharged from the installation position.
5. The unit should be protected by an awning from snow in Alpine areas.
6. The discharged air should not blow into prevailing wind.
7. Do not face the air outlet directly at a neighbour .
8. The position should not be affected by garbage, oil or flammable materials.
9. The installtion position should not be affected by sea salt spray or sulphides near
a thermal spring.

The unit can be installed on a balcony, roof or other convenient place if there is a
suitable load bearing structure to support its weight.
The control panel should not be installed in a bathroom due to high humidity and
moisture.
Leave enough space around the unit for good operation and servicing.
Consider installing rubber pads under the heat pump feet.
Use expansion bolts to fix the feet of the outdoor unit to the ground.
Ensure the condensate water from the heat pump is taken to a drain.

Domestic Hot Water (DHW) Storage Tank and Buffer Tank Installation
The DHW and Buffer tanks may be installed inside or outside.
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.
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.
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.
3.6.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 amd bleeder valve must be included in the hydronic closed loop to allow the
heated water to expand and air to be easily purged from the system.

5. 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 including
Australian Standard AS/NZS3500.4,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. Electrical wiring
6.1 The heat pump outdoor unit should be installed in accordance with electrical
regulations and Australian Standard AS/NZS3000.
6.2 The power cable of the outdoor unit must support the maximum starting current
requirements.
6.3 The outdoor unit power supply circuit must have a grounding wire, which should
connect with a reliable and effective external ground wire.
6.4 Wiring must be installed by qualified technicians with reference to the circuit diagram.
6.5 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.
6.6 When power lines and control lines are parallel, the wires must be placed inside an
insulating tube, with appropriate distance between the lines.
6.7 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:
· Power line
· Remote control three core lines
· Electric heater power line
· Solar circulating water pump control power line
· Water tank electrical boost element
· Temperature sensing line
· Solar collector temperature sensor line
· Terminal equipment
· Outdoor unit lines

7. Installation of the temperature detector
7.1 Firstly, daub heat conductive silicone onto the front of the temperature sensor, then
insert it
into the temperature detector.
7.2 Next, push the temperature sensor with the pin through to the end of the temperature
detector, then mark the level of the pin on the temperature detector.
7.3 Next, pull the pin out and check that the position of mark is at the same level as the
inletof the temperature detector and check whether the sensor is inserted into the pipe
terminal.
7.4 Finally, seal the inlet of the temperature detector with silicone, and keep the inlet of
the temperature detector upright for about an hour.

8. Electrical Wire Selection
8.1 We recommend the following wiring specification to avoid difficulty in starting the compressor
from the initial voltage drop.

8.5.
8.6.
8.7.
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.
To avoid fire, electric shock and other accidents, only use power supply voltage
indicated on the label.
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.
Do not overload wall plugs or the power cable line. Overloading may cause fire or
electric shock.
Check to ensure your electrical socket is appropriate for the power load and is properly
grounded.

9. Trial operation by qualified installer
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 appropriat-
ely lagged.
· Check the power supply and distribution system. Check whether the power supply volta-
ge 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.
9.3 The parameters of the remote controller have been pre-set at the factory. We
recommend that you leave these parameters as set.

1. Wire controller device installation
The remote controller is designed and employed standard electrical box dimensions(86*86,
fixed hole distance 60mm). The electrical box and three core can be built in the wall before
decoration, which makes the interior decoration more perfect. The illustration shows as below:
Unit turn on/off button Note : This icon is to show whether it is under hot water tank
mode or air condition mode. When this icon appears, it shows
that the unit is running air condition mode.
Note : In standby mode, this temperature meaning the ambient
temperature. In hot water tank mode, this temperature meaning
