qualified person in order to avoid a hazard.
An all-pole disconnection switch having a contact separation of at least 3mm in poles should be
connected in fixed wiring.
When carrying out piping connection, take care not to let air substances go into refrigeration cycle.
Otherwise, it will cause lower capacity, abnormal high pressure in the refrigeration cycle, explosion
and injury.
Do not modify the length of the power supply wire or use of extension wire, and do not share the
single outlet with other electrical units. Otherwise, it will cause fire or electrical shock.
Carry out the specified installation work after taking into account strong winds, typhoons or
earthquakes. Improper installation work may result in the equipment falling and causing accidents.
If the refrigerant leaks during installation, ventilated the area immediately. Toxic gas may be
produced if the refrigerant comes into the place contacting with fire.
The temperature of refrigerant circuit will be high, please keep the interconnection cable away from
the copper tube.
After completing the installation work, check that the refrigerant does not leak. Toxic gas may be
produced if the refrigerant leaks into the room and comes into contact with a source of fire, such as a
fan heater, stove or cooker.
The unit shall be installed in accordance with national wiring regulations.
An all-pole disconnection device which has at least 3mm separation distance in all poles and a
residual current device (RCD) with the rating of above 10mA shall be incorporated in the fixed wiring
according to the nation rule.
The power wire type designation is H05RN-R / H07RN-F or above.
CAUTION:
Ground the air conditioner. Do not connect the ground wire to gas or water pipes, lightning rod or a
telephone ground wire. Incomplete grounding may result in electric shocks.
Be sure to install an earth leakage breaker. Failure to install an earth leakage breaker may result in
electric shocks.
Connect the outdoor unit wires, and then connect the indoor unit wires. You are not allowed to
connect the air conditioner with the power source until wiring and piping of the air conditioner is
done.
