6. leakage, 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 is strongly recommended to install with Earth Leakage Circuit Breaker (ELCB) or Residual Current Device (RCD).

9. Otherwise, it may cause electrical shock and fire in case equipment breakdown or insulation 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.

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

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

16. with 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

18.

19.

and injury.

 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 less than 40 mg/10 m.

1. of 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

3. 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.

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).

Power supply connection to the room air conditioner. Use power supply cord 3 × 1.5 mm² (3/4 ~ 1.75HP) type designation 60245 IEC 57 or heavier cord.

12.1 Basic Function

Inverter control, which equipped with a microcomputer in determining the most suitable operating mode as time passes, automatically adjusts output power for maximum comfort always. In order to achieve the suitable operating mode, the microcomputer maintains the set temperature by measuring the temperature of the environment and performing temperature shifting. The compressor at outdoor unit is operating following the frequency instructed by the microcomputer at indoor unit that judging the condition according to internal setting temperature and intake air temperature.

12.1.1 Internal Setting Temperature

Once the operation starts, remote control setting temperature will be taken as base value for temperature shifting processes. These shifting processes are depending on the air conditioner settings and the operation environment. The final shifted value will be used as internal setting temperature and it is updated continuously whenever the electrical power is supplied to the unit.
