CAUTION

WARNING

1. Safety Precautions

 Read the following “SAFETY PRECAUTIONS” carefully before perform any servicing.

 Electrical work must be installed or serviced by a licensed electrician. Be sure to use the correct rating of the

power plug and main circuit for the model installed.

 The caution items stated here must be followed because these important contents are related to safety. The

meaning of each indication used is as below. Incorrect installation or servicing due to ignoring of the instruction

will cause harm or damage, and the seriousness is classified by the following indications.

This indication shows the possibility of causing death or serious injury.

This indication shows the possibility of causing injury or damage to properties.

 The items to be followed are classified by the symbols:

 Carry out test running to confirm that no abnormality occurs after the servicing. Then, explain to user the

operation, care and maintenance as stated in instructions. Please remind the customer to keep the operating

instructions for future reference.

1. Do not modify the machine, part, material during repairing service.

2. If wiring unit is supplied as repairing part, do not repair or connect the wire even only partial wire break. Exchange the whole wiring unit.

3. Do not wrench the fasten terminal. Pull it out or insert it straightly.

4. Engage dealer or specialist for installation and servicing. If installation of servicing done by the user is defective, it will cause water leakage,

electrical shock or fire.

5. Install according to this installation instructions strictly. If installation is defective, it will cause water leakage, electric shock or fire.

6. Use the attached accessories parts and specified parts for installation and servicing. Otherwise, it will cause the set to fall, water leakage, fire

or electrical shock.

7. Install at a strong and firm location which is able to withstand the set’s weight. If the strength is not enough or installation is not properly done,

the set will drop and cause injury.

8. For electrical work, follow the local national wiring standard, regulation and the installation instruction. An independent circuit and single outlet

must be used. If electrical circuit capacity is not enough or defect found in electrical work, it will cause electrical shock or fire.

9. This equipment is strongly recommended to install 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.

10. Do not use joint cable for indoor / outdoor connection cable. Use the specified Indoor/Outdoor connection cable, refer to installation instruction

CONNECT THE CABLE TO THE INDOOR UNIT and connect tightly for indoor / outdoor connection. Clamp the cable so that no external force

will be acted on the terminal. If connecting or fixing is not perfect, it will cause heat up or fire at the connection.

11. 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

heat-up or fire at the connection point of terminal, fire or electrical shock.

12. When install or relocate air conditioner, do not let any substance other than the specified refrigerant, eg. air etc. mix into refrigeration

cycle (piping). (Mixing of air etc. will cause abnormal high pressure in refrigeration cycle and result in explosion, injury etc.).

13. Do not install outdoor unit near handrail of veranda. When installing air-conditioner unit at veranda of high rise building, child may climb up to

outdoor unit and cross over the handrail and causing accident.

14. 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 electric shock in case equipment breakdown or insulation breakdown.

15. Keep away from small children, the thin film may cling to nose and mouth and prevent breathing.

16. Do not use unspecified cord, modified cord, joint cord or extension cord for power supply cord. Do not share the single outlet with

other electrical appliances. Poor contact, poor insulation or over current will cause electrical shock or fire.

17. 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.

18. During pump down operation, stop the compressor before remove the refrigeration piping. (Removal of compressor 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.)

This symbol denotes item that is PROHIBITED from doing.

CAUTION

WARNING

19. During installation, install the refrigerant piping properly before run the compressor. (Operation of compressor without fixing refrigeration piping

and valves at opened condition will caused suck-in of air, abnormal high pressure in refrigeration cycle and result in explosion, injury etc).

20. After completion of installation or service, confirm there is no leakage or refrigerant gas. It may generate toxic gas when the refrigerant

contacts with fire.

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.

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).

7. 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 shall be the place where there is ease for access for the power disconnection in case of emergency. In some countries,

permanent connection of this room air conditioner to the power supply is prohibited.

i. Power supply connection to the receptacle using a power plug. Use an approved 15/16A (3/4~1.5HP) or 16A (2.0HP) or 20A (2.5HP) or

25A (3.0HP) power plug with earth pin for the connection to the socket.

ii. Power supply connection to a circuit breaker for the permanent component. Use an approved 16A (3/4~2.0HP) or 20A (2.5HP) or

25A (3.0HP) circuit breaker for the permanent connection. It must be a double pole switch with a minimum 3.0 mm contact gap.

8. Do not release refrigerant during piping work for installation, servicing, reinstallation and during repairing a refrigerant parts. Take

care of the liquid refrigerant, it may cause frostbite.

9. Installation or servicing work: It may need two people to carry out the installation or servicing work.

10. Do not install this appliance in a laundry room or other location where water may drip from the ceiling, etc.

11. Do not sit or step on the unit, you may fall down accidentally.

12. Do not touch the sharp aluminium fins or edges of metal parts.

If you are required to handle sharp parts during installation or servicing, please wear hand glove.

Sharp parts may cause injury.
