Preparation before installation
Please have a qualifi ed licensed professional technician handle the installation of this unit. Users
•
may not install, repair or displace the air conditioner by themselves.
Set a special circuit. The voltage fl uctuation shall not /-10% of the rated voltage, the
•
electric power wire must separated from the welding transformer, because it will cause greater
voltage fl uctuation.
Please have a qualifi ed licensed professional technician handle the installation of this unit strictly
•
in accordance with the national electric power standard and the regulations of local electric
power department. Inspect whether the circuit capacity satisfi es the requirement, whether the
electric power wire becomes loose or has any damage.
Precautions during installation
Please make sure not touch the fi ns of the heat exchanger, because them will be possibly
•
damaged, causing performance degradation or fi ngers scarifi cation.
Cover plate of the electrical control box must be installed securely, to prevent dust or moisture
•
from entering it. The electrical part must be against damp and far away the water source,
otherwise electric shock or fi re may be caused.
After completion of installation, air tightness test must be done for the pipeline, to check if there
•
is any leakage.
Precautions for the device adopting R140A refrigerant
Fill the cooling system fi rstly with the liquid refrigerant. If gas refrigerant is fi lled, composition of
•
the refrigerant inside the system will be changed.
No other refrigerant will be mixed.
•
The following tools used for the system adopting normal refrigerant (such as R22) shall not be
•
applied: testing device for pipe pressure, fi ll hose, gas leak detector, refrigerant fi lling seat and
refrigerant recovery plant, etc.
Electronic check valve shall be provided additionally to avoid oil backfl ow in the vacuum pump.
•
Precautions during trial operation
When the system is fi rstly powered on or is applied after long-time power off, the outdoor
•
unit must be powered on before 24h of the operation, then the unit can be put into operation,
otherwise the compressor will be burnt (the air conditioner will be in the power-on state during
