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.

Time Delay Safety Control
ϥ The Compressor will not turn on within 3 minutes from the moment operation stops, although the unit is turned on
again by pressing OFF/ON button at remote control within this period.
ϥ This control is not applicable if the power supply is cut off and on again.
ϥ This phenomenon is to balance the pressure inside the refrigerant cycle.
13.1.2 30 Seconds Forced Control
ϥ Once the air conditioner is turned on, the compressor will not stop within 30 seconds in a normal operation
although the intake air temperature has reached the thermo-off temperature. However, force stop by pressing the
OFF/ON button at the remote control is permitted or the Auto OFF/ON button at indoor unit.
ϥ The reason for the compressor to force operation for minimum 30 seconds is to allow the refrigerant oil run in a
full cycle and return back to the outdoor unit.
13.1.3
Total running current control
1. If the outdoor unit total running current is detected exceeding I1(A), the frequency instructed for compressor
operation will be decreased.
