This symbol denotes item that is PROHIBITED from doing.

WARNING

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.

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

4. 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.

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

6. fire or electrical shock.

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

7. done, the set will drop and cause injury.

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

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

This equipment must installed with an Earth Leakage Circuit Breaker (ELCB) or Ground Fault Current Interrupter (GFCI) or Appliance

9.

Leakage Current Interrupter (ALCI) that has been certified by an NRTL Certified Testing Agency and that is suitable for the voltages and amperages involved. Otherwise, if may cause electrical shock and fire in case of equipment breakdown. Do not use joint cable for indoor / outdoor connection cable. Use the specified Indoor/Outdoor connection cable, refer to installation

10.

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.

Wire routing must be properly arranged so that control board cover is fixed properly. If control board cover is not fixed perfectly, it will

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

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

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

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

13. up to outdoor unit and cross over the handrail and causing accident.

This equipment must be properly earthed. Earth line must not be connected to gas pipe, water pipe, earth of lightning rod and

14. 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.

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

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

Tighten the flare nut with torque wrench according to specified method. If the flare nut is over-tightened, after a long period, the

17. flare may break and cause refrigerant gas leakage.

For R410A model, use piping, flare nut and tools which is specified for R410A refrigerant. Using of existing (R22) piping, flare nut and tools may cause abnormally high pressure in the refrigerant cycle (piping), and possibly result in explosion and injury.

18. Thickness or copper pipes used with R410A must be more than 1/32" (0.8 mm). Never use copper pipes thinner than 1/32"

(0.8 mm). It is desirable that the amount of residual oil is less than 0.0008 oz/ft (40 mg/10 m). During installation, install the refrigerant piping properly before run the compressor. (Operation of compressor without fixing refrigeration

19.

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

3

WARNING

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

20. operating and valves are opened will cause suck-in of air, abnormal high pressure in refrigeration cycle and result in explosion, injury etc.)

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

21. contacts with fire.

22. Ventilate if there is refrigerant gas leakage during operation. It may cause toxic gas when refrigerant contacts with fire.

23. Do not insert your fingers or other objects into the unit, high speed rotating fan may cause injury.

24. Must not use other parts except original parts described in catalog and manual.

25. Using of refrigerant other than the specified type may cause product damage, burst and injury etc.

CAUTION

Do not install the unit at place where leakage of flammable gas may occur. In case gas leaks and accumulates at surrounding of

1. the unit, it may cause fire.

Carry out drainage piping as mentioned in installation instructions. If drainage is not perfect, water may enter the room and damage the

2. furniture.

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

3. 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.

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.

6.

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).

Power supply connection to the room air conditioner. Power supply cord shall be UL listed or CSA approved 3 conductor with minimum AWG14 wires. Power supply point should be in an easily accessible place for power disconnection in case of emergency.
