WARNING
21. Ventilate if there is refrigerant gas leakage during operation. It may cause toxic gas when refrigerant contacts with fire.
22. Do not insert your fingers or other objects into the unit, high speed rotating fan may cause injury.
23. Must not use other parts except original parts described in catalog and manual.
24. Using of refrigerant other than the specified type may cause product damage, burst and injury etc.
CAUTION
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.
Carry out drainage piping as mentioned in installation instructions. If drainage is not perfect, water may enter the room and damage the
furniture.
3.
Tighten the flare nut with torque wrench according to specified method. If the flare nut is over-tightened, after a long period, the flare may
break and cause refrigerant gas leakage.
4.
Do not touch outdoor unit air inlet and aluminium fin. It may cause injury.
5.
Select an installation location which is easy for maintenance.
6.
Pb free solder has a higher melting point than standard solder; typically the melting point is 50°F – 70°F (30°C – 40°C) higher.
Please use a high temperature solder iron. In case of the soldering iron with temperature control, please set it to 700 ± 20°F (370 ± 10°C).
Pb free solder will tend to splash when heated too high (about 1100°F / 600°C).

the power supply cord of the air conditioner to the mains using one of the following method. 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 power plug.
Use an approved 15/16A (1.0 ~ 1.5HP) or 16A (2.0HP) or 20A (2.5HP) power plug with earth pin for the connection to the socket.
2) Power supply connection to a circuit breaker for the permanent connection.
Use an approved 16A (1.0 ~ 2.0HP) or 20A (2.5HP) circuit breaker for the permanent connection. It must be a double pole switch with
a minimum 3.0 mm contact gap.
8.
CS/CU-A28PKD
Power supply connection to the room air conditioner.
Use power supply cord 3 × 4.0 mm² type designation 60245 IEC 57 or heavier cord.
Connect the power supply cord of the air conditioner to the mains using one of the following method.
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 power plug.
Use an approved 25A power plug with earth pin for the connection to the socket.
2) Power supply connection to a circuit breaker for the permanent connection.
Use an approved 25A circuit breaker for the permanent connection. It must be a double pole switch with a minimum 3.0 mm contact
gap.
9.
