CAUTION

•

Wrong wiring may cause a burn-out of some electrical parts.

• Be sure to use the cord clamps attached to the product.
• Do not damage or scratch the conductive core or inner insulator of the

power and inter-connecting wires when peeling them.

• Use the power and Inter-connecting wires with specifi ed thicknesses,

specifi ed types and protective devices required.

WARNING

1. Using the specifi ed wires, ensure that the wires are connected,

and fi x wires securely so that the external tension to the wires
does not affect the connecting part of the terminals.

Incomplete connection or fi xation may cause a fi re, etc.

2. Be sure to connect the earth wire. (grounding work) Incomplete

grounding may lead to electric shock.

Do not connect ground wires to gas pipes, water pipes, lightning rods

or ground wires for telephone wires.

3. 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 fi re.

• Remove the panel, and you can see electric parts on the front side.
• A metal pipe can be installed through the hole for wiring. If the hole

size does not fi t the wiring pipe to be used, drill the hole again to an
appropriate size.

• Be sure to clamp the power wires and indoor/outdoor connecting wires

with a banding band along the connecting pipe so that the wires do not
touch the compressor or discharge pipe.

(The compressor and the discharge pipe become hot.)
Furthermore, be sure to secure these wires with the pipe valve fi xing plate

and cord clamps stored in the electric parts box.

• Connect the indoor/outdoor connecting wires to the identical terminal

numbers on the terminal block of each unit.

Incorrect connection may cause a failure.

For the air conditioner, connect a power wire with the following specifi cations.

respective numbers on the terminal block of the indoor and outdoor units.

H07RN-F or 60245 IEC66 (1.5 mm

or more)

2. When connecting the connecting wire to the outdoor unit terminal, prevent

water from coming into the outdoor unit.

3. Insulate the unsheathed cords (conductors) with electrical insulation tape.

Process them so that they do not touch any electrical or metal parts.

4. For interconnecting wires, do not use a wire joined to another on the way.

Use wires long enough to cover the entire length.

Wiring Connection

1. Remove the valve cover, the electric parts cover and the cord clamp from

the outdoor unit.

2. Connect the connecting cable to the terminal as identifi ed by the matching

numbers on the terminal block of indoor and outdoor unit.

3. Insert the power cord and the connecting cable carefully into the terminal

block and secure it tightly with screws.

4. Use vinyl tape, etc. to insulate the cords which are not going to be used.
Locate them so that they do not touch any electrical or metal parts.
5. Secure the power cord and the connecting cable with the cord clamp.
6. Attach the electric parts cover and the valve cover on the outdoor unit.

Electrical Work

• While the valve is fully opened, after the screwdriver has reached the

stopper, do not apply torque exceeding 5 N·m. Applying excessive torque
may damage the valve.
