WARNING
17.
During installation, install the refrigerant piping properly before run the compressor. Operation of compressor without fixing
refrigeration piping and valves at opened condition will cause suck-in of air, abnormal high pressure in refrigeration cycle and result in
explosion, injury etc.

CAUTION
1.
Do not install the Indoor Unit at place where leakage of flammable gas may occur. In case gas leaks and accumulates at surrounding
of the unit, it may cause fire.
of the unit, it may cause fire.
2.
Do not release refrigerant during piping work for installation, re-installation and during repairing a refrigeration parts. Take care of the
liquid refrigerant, it may cause frostbite.
liquid refrigerant, it may cause frostbite.
3. Do not install this appliance in a laundry room or other high humidity location. This condition will cause rust and damage to the unit.
4. Make sure the insulation of power supply cord does not contact hot part (i.e. refrigerant piping) to prevent from insulation failure (melt).
5.
Do not apply excessive force to water pipes that may damage the pipes. If water leakage occurs, it will cause flooding and damage to
other properties.
other properties.
6. Select an installation location which is easy for maintenance.
7.
Carry out drainage piping as mentioned in installation instructions. If drainage is not perfect, water may enter the room and damage
the furniture.
the furniture.
8.
Power supply connection to Indoor Unit.
Power supply point should be in easily accessible place for power disconnection in case of emergency.
Must follow local national wiring standard, regulation and this installation instruction.
Strongly recommended to make permanent connection to a circuit breaker.
-
-
Power supply 1: Use approved 30A 2-poles circuit breaker with a minimum contact gap of 3.0 mm.
-
Power supply 2: Use approved 30A 2-poles circuit breaker with a minimum contact gap of 3.0 mm.
9. Ensure the correct polarity is maintained throughout all wiring. Otherwise, it will cause electrical shock or fire.
10.
After installation, check the water leakage condition in connection area during test run. If leakage occurs, it will cause damage to other
properties.
