■ Heat insulation for pipe
• Apply heat insulation of pipe separately at the liquid, gas, and balance sides.
• Be sure to use thermal insulator resistant up to 120°C or higher for pipes at the gas side.
■ Finishing after connecting pipes
• After piping connection work has been fi nished, cover the opening of the piping/wiring panel with the piping
cover, or fi ll silicon or putty into the space between the pipes.
• In case of drawing-out the pipes downward or sideward, also close the openings of the base plate and the side

Electric wiring

WARNING
The appliance shall be installed in accordance with national wiring regulations.
Capacity shortages of the power circuit or an incomplete installation may cause an electric shock or fire.
CAUTION
• Perform wiring of power supply complying with the rules and regulations of the local electric company.
• Do not connect 380V - 415V power to the terminal blocks for control cables (U1, U2, U3, U4, U5, U6, U7, U8);
otherwise, the unit may break down.
• Be sure that electric wiring does not come into contact with high-temperature parts of piping; otherwise, the
coating of cables may melt and cause an accident.
• After connecting wires to the terminal block, take off the traps and fi x the wires with cord clamps.
• Follow the same structure for both the control wiring and refrigerate piping.
• Do not conduct power to indoor units until vacuuming of the refrigerant pipes has fi nished.
• For the wiring of power to indoor units and that between indoor and outdoor units, follow the instructions in the
installation manual of each indoor unit.
■ Power supply specifi cations
Do not bridge the power between outdoor units
through the equipped terminal blocks (L1, L2, L3, N).
