6. Trial running
6-1 Inspection and confirmation before debugging
1) Check and make sure the refrigerating pipeline and communication
line between the indoor and outdoor units are in the same refrigerating
system, or some operation fault may occur.
2) The voltage power supply is within ±10% of the rated voltage.
3) Check and make sure the power supply line and control line are
correctly connected.
4) Make sure there is not short circuit before the system is electrified.
5) Make sure all units have passed the 24h nitrogen pressure
maintaining test (4.0MPa).
6) Make sure the system is fully vacuumized, dried and filled with the
refrigerant as per the specification.
6-2 Preparation before debugging
1) Calculate the amount of refrigerant to be refilled as per the field liquid
tube length.
2) Prepare the required refrigerant.
3) Prepare the system planar drawing, system pipeline drawing and
control line drawing.
4) Record the well set address codes on the system planar drawing.
5) Turn on the outdoor unit power supply switch in advance, and make
sure it is connected for more than 12h to make the heater heating the
compressor oil.
6) Fully open the outdoor unit gas tube check valve, liquid tube check
valve and oil balance valve, or the machine may be damaged.
7) Check if the phase sequence of the outdoor unit power supply is
correct.
8) Check if all dialing switches of the outdoor and indoor units are set as
per the product technical requirement.
6-3 Name filling of connected systems
When setting several indoor units, each connecting system of the indoor
unit and outdoor units shall be identified and named and recorded on the
nameplate of outdoor unit electrical control box cover.

6-4 Precautions against refrigerant leakage
1) The refrigerant itself of this air conditioner is harmless, nonflammable
and safe.
2) The air conditioner room shall be of a suitable space size so that the
refrigerant concentration will not go beyond the limit even if leakage
happens, and some necessary measures can be taken additionally.
3) The critical gas concentration harmless for the human body is
³
0.3kg/m .
4) Confirm the critical concentration as per the following steps and take
necessary measures correspondingly.
1. Calculate the full volume of refrigerant to be filled (A[kg])
Full refrigerant volume = refrigerant volume at delivery (see the
nameplate) + refrigerant volume to be refilled for the corresponding tube
length
2. Calculate the indoor cubage (B[m ]) (as per the minimum cubage)
3. Calculate the refrigerant concentration
A[kg]
≤ critical concentration:
B[m³]

5) Measures against exceeding the critical concentration
1. To control the refrigerant concentration below the critical
concentration, a mechanical air ventilating device shall be installed (for
frequent air ventilating).
2.If frequent air ventilating cannot be realized, please install a leakage
warning and detecting apparatus interlinked with the mechanical air
ventilating device.
3.The leakage warning and detecting apparatus shall be installed in a
place with dense refrigerant accumulation.

6-5 Hand over to the client
1) The Instruction Manual for the indoor unit, Instruction Manual for the
outdoor unit and Direction for Customer Service must be submitted to the
client.
2) Explain the content of Instruction Manual to the client carefully.
