• Disconnect switch for over current protection given in the table below is to be installed
between the indoor unit and the outdoor unit.
• Use ring terminals and tighten the terminal screws to the specifi ed torques, otherwise,
abnormal overheating may be produced and possibly cause heavy damage inside the
unit.
• Match the terminal block numbers and connection cable colors with those of the
outdoor unit. Erroneous wiring may cause burning of the electric parts.
• Connect the connection cables fi rmly to the terminal block. Imperfect installation may
cause a fi re.
• Always fasten the outside covering of the connection cable with the cable clamp. (If
the insulator is chafed, electric leakage may occur.)
• Securely earth the power cable plug.
• Do not use the earth screw for an external connector. Only use for interconnection
between two units.

• Be sure to comply with local codes while running the wire from the indoor unit to the
outdoor unit (size of wire and wiring method, etc.).
• Every wire must be connected fi rmly.
• No wire should be allowed to touch refrigerant tubing, the compressor or any moving
part.
• Loose wiring may cause the terminal to overheat or result in unit malfunction. A fi re
hazard may also exist. Therefore, be sure all wiring is tightly connected.

How to connect wiring to the terminal
Caution when wiring cable
When stripping off the coating of a lead wire, always use a special tool such as a wire
stripper. If there is no special tool available, carefully strip the coating with a knife etc.
(1) Use ring terminals with insulating sleeves as shown in the fi gure below to connect
to the terminal block.
(2) Securely clamp the ring terminals to the wires using an appropriate tool so that the
wires do not come loose.
Strip: 3/8 in
(10 mm)
(3) Use the specifi ed wires, connect them securely, and fasten them so that there is no
stress placed on the terminals.
(4) Use an appropriate screwdriver to tighten the terminal screws. Do not use a
screwdriver that is too small, otherwise, the screw heads may be damaged and
prevent the screws from being properly tightened.
(5) Do not tighten the terminal screws too much, otherwise, the screws may break.

7. TEST RUN

Make a TEST RUN in accordance with installation manual for the indoor unit.
CHECK ITEMS
INDOOR UNIT
For check items refer to the installation manual for the indoor unit.
OUTDOOR UNIT
(1) Is there any abnormal noise and vibration during operation?
(2) Will noise, wind, or drain water from the unit disturb the neighbors?
(3) Is there any gas leakage?
CAUTION
Always turn on the power 12 hours prior to the start of the operation in order to ensure
