tighten with wrench.
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.

E: After the air discharging(vacuumming),disconnect
the connecting between the pressure gauge and
indoor unit stop valve .
F: Open the stop valve at indoor unit high/low pressure
side by valve plug, then let the indoor unit's refrigerant
flow in outdoor unit(if need to add more refrigerant, please refer to 2.4).
When the pipe is too long, please add
additional refrigerant as following formula:
Additional refrigerant amount=
(one-way tube length -5)m 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 .

normal, the power distribution accessory screws all tighten, supply power is in compliance
with the wiring diagram and the wire is grounded well.
7.1c 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.
7.2 Trial operation
7.2a 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 sound during operation. 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.
7.2b 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.
7.2c Observe whether the outlet water temperature is normal.
7.2d Parameter of the remote controller has been set before leave of the factory. Never alternate
them personally.

6.3 Caution ofGround The internal motorprotector does not protectthe compressor against all
possible conditions Please be surethat the system utilizesthe ground connection when installed
in the field.
6.4 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.
