KEY POINTS IN INSTALLATION
INSTALLATION
Confirm the model and name of your air conditioner

REFRIGERANT PIPING
Separately purchased refrigerant distributor (branch
joint, branch header pipe) should be used in the process
of refrigerant piping.
Charge nitrogen under certain pressure in the refrigerant
piping before welding.
Heat insulation should be done to refrigerant piping.
After the installing refrigerant piping, do not electrify the
indoor unit before the airtight test and vacuum.
Refrigerant piping should accord with specified
diameter.
AIRTIGHT TEST
Refrigerant piping must be tested for gas proof
2
[2.94MPa(30kg/cm ) nitrogen.]
VACUUM
Vacuum pump must be used, and vacuuming should
be done from the gas side and liquid side
simultaneously.
ADD REFRIGERANT
When the actual pipe is longer than the fiducial length,
the added refrigerant volume of every outdoor unit
depends on the calculating according to the actual length.
Fill the form on the outdoor unit electric control box with
the added volume, length of pipes (actual length) and the
relative height drop between outdoor unit and indoor unit.
WIRING
Choose power capacity and wire diameter according to
the design manual. The power cord of the air conditioner
should be wider than the power cord of ordinary motor.
Connect the indoor unit to the power after airtight test
and vacuuming.
Do not twist or cross the power cord with wiring (low

1. Please keep away from the following place, or
malfunction of the machine may be caused:
2. The insulation of the metal parts of the building and the
