• 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.

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.

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.
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.

• 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.

How to wire
1. Connect the connecting wire to the terminal as identifi ed with their
respective numbers on the terminal block of the indoor and outdoor units.
H07RN-F or 60245 IEC66 (1.5 mm
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.
