Inspect
•
To ensure that the electrical equipment used on the installation site (main power switch, circuit breaker, wire,
conduit and wiring terminals, etc.) have been selected according to current data, to ensure that the device in line
with national standards.
• Check the power supply voltage in the range of 10% of the rated voltage and the ground wire is included in the
power supply line. Otherwise, electrical parts will be damaged.
•
Check whether the power supply is satisfied. Otherwise, the compressor will not start when the voltage is too low.
• By measuring the insulation resistance between the ground and the electrical device terminals, to ensure that
more than 1 MΩ. Otherwise, the system can not be started until the cause of leakage and maintenance.
Connection
• Connect the power cord to the terminal of the indoor unit and the outdoor mechanical and electrical gas box,
connect the ground wire to the grounding bolt of the outdoor machine and the indoor mechanical and electrical air
box.
• Connect the external and internal communication lines to the 1 and the 2 terminals on the terminal. If the power
cord is connected, the printed circuit board will be damaged. And the use of shielded twisted pair wire.
• Do not connect the fastening screws on the front of the cover.
•
The power cord must be made of copper wire, and the power supply must be in line with IEC 60245 requirements.
If the power cord length exceeds 20m, the need to increase the size.
•
The power supply line is fixed with a round connection terminal with an insulating protective sleeve. Not with
sheet metal contact and extrusion, in order to avoid the cut line of skin caused by fire.

•
Power cable must be fixed firmly.
• To avide electrical shock, make sure to disconnect the power supply 1 minute or more before servicing the
electrical parts.Even after 1 minute,always measure the voltage at the terminals of main circuit capacitors or
electrical parts and before touching, make sure that those voltages are 50VDC or less.
• To persons in charge of electrical wiring work: Do not operate the unit until the refrigerant piping is complete.
(Running it before the piping is ready will break the compressor)
• Each outdoor must be earthed well.
• When power cable exceeds the range, thichen it appropriately.
• The appliance shall be installed in accordance with national wiring regulations.
• All wiring must be performed by an authorized electrician.
• Be sure to install an earth leakage circuit breaker in accordance with applicable legislation.Failure to do so many
cause electrical shock.
