Carry out test run 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. Engage dealer or specialist for installation. If installation done by the user is defective, it will cause water leakage, electrical
shock or fire.
2. Install according to this installation instructions strictly. If installation is defective, it will cause water leakage, electrical shock
or fire.
3. Use the attached accessories parts and specified parts for installation. Otherwise, it will cause the set to fall, water leakage,
fire or electrical shock.
4. 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.
5. 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.
6. For electrical work, follow the local national wiring standard, regulation and this 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.
7. 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.
8. 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.
9. Use the specified cable (1.5 mm2) and connect tightly for indoor/outdoor connection. Connect tightly and clamp the cable so
that no external force will be acted on the terminal. If connection or fixing is not perfect, it will cause heat-up or fire at the
connection.
10. 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.
11. 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.
12. Do not damage or use unspecified power supply cord. Otherwise, it will cause fire or electrical shock.
13. Do not modify the length of the power supply cord or use extension cord, and do not share the single outlet with other
electrical appliances. Otherwise, it will cause fire or electrical shock.
14.
• For R410A models, when connecting the piping, do not use any existing (R22) pipes and flare nuts. Using such same
may cause abnormally high pressure in the refrigeration cycle (piping), and possibly result in explosion and injury. Use
only R410A materials.
• Thickness or copper pipes used with R410A must be more than 0.8 mm. Never use copper pipes thinner than 0.8 mm.
• It is desirable that the amount of residual oil is less than 40 mg/10 m.
15. During installation, before run the compressor, confirm the refrigeration pipes are fixed. Operation of compressor
without fixing the piping, setting the 2 way valve and 3 way valve at open condition, a burst may occur and cause injury.
16. During pump down operation, stop the compressor before remove the refrigeration piping. When remove piping while 2 way
valve, 3 way valve at open condition, burst may occur and cause injury.
17. After completion of installation, confirm there is no leakage of refrigerant gas. It may generate toxic gas when the refrigerant
contacts with fire.
18. Ventilate if there is refrigerant gas leakage during operation. It may cause toxic gas when the refrigerant contacts with fire.
