II. Installation
1. Unit installation position
The pretty high condensation temperature (cooling) and pretty low evaporation temperature(heating)
will affect the operation of outdoor unit. To achieve maximum efficiency, please select the installation
position under below regulations: To avoid ventilation short, the outdoor unit discharged air should not
return when installation. Please keep enough space around the outdoor unit for repair. Right and wrong
means as below:
Wrong
Right
As the upwards fan
direction unit
exhausts air
upwards, do not
place any object up
the unit.
Please built an
introductory
equipment if cantu
avoid this object.
Notice:
1. To get enough air for ventilation of the unit, the installation position should be with good ventilation.
2. The installation position can hold the outdoor unit without noise and shake.
3. No sunlight to the unit. Set an awning if necessary.
4. The water from rain and defrosting can be discharged in the installation position.
5. The unit will not be covered by snow in the installation position.
6. The discharged air will not face strong air in the installation position.
7. Assure the noise caused by the unit ventilation and operation will not affect the neighbor.
8. The installation position will not be affected by garbage, oil and mist.
9. The outdoor unit will be damaged under the condition with oil(engine oil), salt(sea area) and
sulfide air(near thermal spring and refining factory).

2.3 Air discharge ( by indoor unit refrigerant)
If the system is small, use refrigerant empty way to discharge the pipe and outdoor unit air, to discharge the
air in the connecting pipe and outdoor unit, when there's refrigerant in the pipes originally, just open the
low pressure side needle valve of indoor unit to discharge the air by refrigerant pressure.
As the following steps:
A: Unscrew the valve plug nut on the stop valve , and unscrew the needle nut on the indoor unit low
pressure side.
B: Open the stop valve at outdoor unit high/low pressure side by valve plug.
C: Open the stop valve at indoor unit's high pressure side by valve plug,
Note: don't open the one at low pressure side.
D: Open the needle valve by small screwdriver , and this outlet will discharge the air in connecting
pipe and outdoor unit at the same time.
E: Close the needle valve after open it about 10-20 seconds ,The time is according to the size of
outdoor unit and the length of the connecting pipe.

2.5 Add refrigerant
When the pipe is too long, please add
additional refrigerant as following formula:
Additional refrigerant amount=
(one-way tube length -5) x (0.015~0.02) kg,
choose 0.015 or 0.02 according to the size
of diameter.
When the tracheal diameter = 12.7,
choose 0.015;
when the diameter = 15.88, choose 0.02 .

2.6 Leak check
After discharge the air, use electronic leak detector or soapy water to test all the
connectors in theindoor and outdoor unit.
3. Water pipe connections
3.1 Pipe should be a kind of pipe that heat-resistant,rust-proof, uneasy-fouling.and in conformity
wit h national health and safety standards, which can be stainless steel pipe, copper pipe, aluminum
water pipe, hot water PPR pipes and so on.
3.2 Water tank outlet pipe and overflow pipe is better to installed around the gutter or sewer,
so that to convenient to drainage.
3.3 The connection of the heat pump unit and water tank must be installed a stop valve or
dismountable loose joint, for maintenance use.
3.4 Water pipes are arranged reasonably to minimize bending and reduce the pressure loss of water
system .
3.5 The connection of tap water pipe and water filling connection must install one-way valve, filter,
supply water solenoid valve (for tank-type water tank) and pressure relief devices (for close-type
valve the parameter value is 0.7MPa), installed when valve body arrow is same as with the flow
direction to prevent water block. The cycle water outlet of the heat pump unit should connect to
the inlet of water tank , The cycle water inlet of the heat pump unit should connect to the outlet of
water tank, the water supply inlet of the tank should connect to the heat water supply outlet .
The entire piping system should be clean, no rust and dirt residue to prevent pipe blockage.
3.6 After the installation of the water filling pipe and cycle water pipe and hot water supply pipe ,
a ll the pipes should take the water tightness test. And ensure that the system is clean. And then
cover insulation on the pipe and valve (including the supply water pipes and valves).
3.7 Power line and signal line layout should be neat, rational, strong and weak lines separating cable
and Can not interfere with each other, without contact with the connecting pipe and valve.
3.8 After the construction of all wiring is completed, carefully check the correct order to connect the
power.
3.9 Unit electric wire connection: connect to the appropriate terminals according to wiring diagram,
and fix it by the pressure line of board in the electrical box.
3.10 All the wiring construction is completed, can be plugged in only after careful examination correctly.
3.11 Unit control board fuse parameters: 5A/220V.
3.12 The unit wire controller must be fixed in the bottom of standard electrical switch box.

4.3 Caution of Ground The internal motor protector does not protect the compressor against all
possible conditions Please be sure that the system utilizes the ground connection when installed
in the field.
4.4 Warning: To avoid fire, electric shock and other accidents, keep in mind about these tips:
A: Only use power supply voltage indicated on the label, if you do not know the family of voltage,
contact the dealer or local power company.
B: When you use the unit by the maximum current please view the specifications, so make sure
our home's power supply (current, voltage and cable) to meet the machine's normal load
requirements.
C: To protect the power lines. Power lines should be fixed, so that people will not be trip over or
the lines damaged by other things. Paying particular attention to plugs, which should be easily
plug into the socket, careful the plug position.
D: Do not overload wall plugs or extension the cable. Line overload can cause fire or electric shock.
E: To ensure your safety, you must plug the power lines into the socket with a grounded three-phase,
and check to ensure your socket is accurate and reliable grounding.

6.Trial operation(should be operated by professionals)
5.1 Check before trial operation
A: Check the pipe system. Check the whole pipe system. Ensure the water volume in the system is
full and the air is exhausted complet ely. Check whether the valve is open throughout the system
and the thermal insulating of the pipe is well.
B: Check the power supply and distribution system. Check whether the power supply voltage is
normal, the power distribution accessory screws all tighten, supply power is in compliance with
the wiring diagram and the wire is grounded well.
C: Check the air cooled water chiller. Check whether any screw loose. Check the signal indicator
light (green) of the outdoor unit control panel is illuminated normally and the fault indicating
lamp(red) is illuminated. Connect the pressure gauge to the freon feed mouth for checking the
pressure during operation. Disconnect them after test is ok.
5.2 Trial operation
A: Press on/off in the remote controller turn on the hot water circulating pump whether the
water pump operates normally. Observe and determine whether air pipe is exhausted completely,
flow switch is closed, hydraulic pressure indicated in the pressure gauge is more than 0.2MPa.
Come to next step after confirm the circulating water system works normally.
B: Press on/off in the remote controller, the water pump and fan start immediately.
The compressor start after the unit operates for some time. Observe and determine if there's
any abnormal soun d during operatio n. Stop to check the unit if there's abnormal sound. The unit
can continue to run only when there's no abnormal sound. Check whether the cooling system
pressure is normal at the same time.
C: Check whether the input power and current of the unit are compliance with the parameter in this
Instruction. If not, stop to check the unit.
D: Observe whether the outlet water temperature is normal.
E: Parameter of the remote controller has been set before leave of the factory. Never alternate them
personally.
