16. Wire routing must be properly arranged so that control board cover is fixed properly. If control board cover is
not fixed perfectly, it will cause fire or electrical shock.
17. This equipment is strongly recommended to be installed with Earth Leakage Circuit Breaker (ELCB) or
Residual Current Device (RCD). Otherwise, it may cause electrical shock and fire in case equipment
breakdown or insulation breakdown.
18. During installation, install the refrigerant piping properly before running 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.
19. During pump down operation, stop the compressor before remove the refrigeration piping. Removal of
refrigeration piping while compressor is operating and valves are opened will cause suck-in of air, abnormal
high pressure in refrigeration cycle and result in explosion, injury etc.
20. Tighten the flare nut with torque wrench according to specified method. If the flare nut is over-
a long period, the flare may break and cause refrigerant gas leakage.
21. After completion of installation or service, confirm there is no leakage of refrigerant gas. It may generate
toxic gas when the refrigerant contacts with fire.
22. Ventilate if there is refrigerant gas leakage during operation. It may cause toxic gas when the refrigerant
contacts with fire.
23. Recommended installation height for indoor unit shall be at least 2.5 m.
24. The appliance shall be installed in accordance with national wiring regulations.
25. Indoor unit must be installed close against the wall.
26. When carrying out piping connection, take care not to let air substances other than the specified refrigerant
go into refrigeration cycle. Otherwise, it will cause lower capacity, abnormal high pressure in the
refrigeration cycle, explosion and injury.
27. Must not use other parts except original parts describe in catalog and manual.
28. This equipment must be properly earthed. Earth line must not be connected to gas pipe, water pipe, earth of
lightning rod and telephone. Otherwise, it may cause electrical shock in case equipment breakdown or
insulation breakdown.
1. Do not install the 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.
2. Do not release refrigerant.
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.
3. Do not install this appliance in a laundry room or other location where water may drip from the ceiling, etc.
4. Thermal fuse specification for indoor unit: 250V 3.15A T3.15AL; outdoor unit: 250V 3.15A T3.15AL.
5. Do not touch the sharp aluminium fin, sharp parts may cause injury.
6. Carry out drainage piping as mentioned in installation instructions. If drainage is not perfect, water may enter
the room and damage the furniture.
7. Select an installation location which is easy for maintenance.
8. Power supply connection to the air conditioner.
Connect the power supply cord of the air conditioner to the mains using one of the following methods.
Power supply point should be in easily accessible place for power disconnection in case of emergency.
In some countries, permanent connection of this air conditioner to the power supply is prohibited.
1) Power supply connection to the receptacle using a power plug.
Use an approved 15/16A power plug with earth pin for the connection to the receptacle.
2) Power supply connection to a circuit breaker for the permanent connection. Use an approved 16A circuit
breaker for the permanent connection. It must be a double pole switch with a minimum 3.5 mm contact gap.
9. Installation or servicing work.
It may need two people to carry out the installation and service work.
