1 SAFETY PRECAUTIONS Power supply cord of outdoor unit shall be 2.5 mm (H07RN-F or 60245IEC66) polychloroprene sheathed flexible cord. • Read this “SAFETY PRECAUTIONS” carefully before Installation. • The precautions described below include the important items regarding safety. Observe them without fail. •...

• When installing the air conditioner in a small room, provide appropriate measures to ensure that the concentration of refrigerant in the room does not exceed the critical level should leakage occur. It is not dangerous refrigerant; it has not toxicity or combustibility. However, a concentration above 0.3 kg/m³ as criterion still causes suffocation.
3 SELECTION OF INSTALLATION PLACE WARNING • Install the air conditioner where there is sufficient strength to withstand the weight of the unit. If the strength is not sufficient, the unit may fall down resulting in injury. • Install the air conditioner at a position keeping the height by 2.5 m or more from the floor. If you insert your hands or others directly into the unit during running of the air conditioner, it is dangerous because you may contact with revolving fan or active electricity.
4 INSTALLATION OF INDOOR UNIT WARNING Install the air conditioner certainly at a place to sufficiently withstand the weight. If the strength is insufficient, the unit may fall down resulting in human injury. Perform a specified installation work to guard against an earthquake. An incomplete installation can cause accidents by the units falling and dropping.

Installation reference The air supply ducting work is classified into two ways, one is branched by the square ducts, and the other is branched by the round ducts. (Be sure to divide the air supply duct into three or more branches.) Square duct In case of using the square duct, apply the thermal insulator of thickness by 25 mm or more to the duct board.

Points at installation work General cautions Considering installation places of indoor unit and supply chamber, and structure of the building, determine the duct path. In order to utilize the static pressure characteristics of the air supply in the indoor unit, design the duct branching by setting size up to the air supply chamber or by setting length to the first branch as long as possible (Min.
6 DRAIN PIPING WORK Piping material • For laying pipes under ground, use hard vinyl chloride pipe. (Inner diam. 20 or 25 mm) Piping and cautions • Set drain side of pipe at downward slope. (1/100 or more) • Be sure to apply thermal insulation (foaming polyethylene, 10 mm-thickness or 1.5 m to 2 m Indoor more) for pipes passing through the room.
7 REFRIGERANT PIPING Refrigerant Piping If the outdoor units are to be mounted on a wall, make sure that the platform supporting is sufficiently strong. The platform should be designed and manufactured to maintain its strength over a long period of time, and sufficient consideration should be given to ensuring that the outdoor unit will not fall.

Tightening connection Align the centers of the connecting pipes and tighten the flare nut as far as possible with your fingers. Then tighten the nut with a spanner and torque wrench as shown in the figure. CAUTION • Do not apply excess torque. Otherwise, the nut may crack depending on the conditions.

8 EVACUATING EVACUATION Evacuate the air in the connecting pipes and in the indoor unit using vacuum pump. Do not use the refrigerant in the outdoor unit. For details, see the manual of vacuum pump. Use a vacuum pump Be sure to use a vacuum pump with counter-flow prevention function so that inside oil of the pump does not flow backward into pipes of the air conditioner when the pump stops.
9 ELECTRICAL WORK For the air conditioner that has no power cord. NOTE For selection and connection method of the power supply cords, refer to the details in the Installation Manual of the outdoor unit. CAUTION • If incorrect/incomplete wiring is carried out, it will cause an electrical fire or smoke. •...
Check and Test Operation Be sure to test the piping connections for gas leaking. • Check the flare nut connections, valve stem cap connections and service port cap connections for gas leak with a leak detector or soap water. Flare nut connections (Indoor unit) •...
