6.2. How to install the connection cable
1. Remove the screws, then remove the conduit holder.
2. Fasten the connection cable to the conduit holder using the lock nut.
IMPORTANT: Refer to fi gure of indoor unit wire length about the length of indoor unit
wire harness.
3. Use the screws to install the conduit holder provided with the indoor unit.
4. Remove the screw to remove the wire cover.
5. Connect the connection cable to the terminal.
Refer to the wiring diagram and “How to connect wiring to the terminals”.

6.3. How to connect wiring to the terminals
Caution when wiring cable
When stripping off the insulation of a lead wire, always use a special tool such as a wire
stripper. If there is no special tool available, carefully strip the insulation 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.

(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 screw-
driver 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.

CAUTION
• Attach the cable clamp fi rmly by holding the connection cable, and make sure that the
clamp is fi xed securely.
Incomplete attachment of the cable clamp might cause a malfunction of the open
panel.
• Match the terminal block numbers and connection cable colors with those of the
outdoor unit or branch box.
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 discharge may occur.)
• Always connect the earth (ground) wire.
• Do not use the earth (ground) screw of the indoor unit for the connection other than a
specifi ed outdoor unit.
7. FINISHING
(1) Insulate between pipes.
• Insulate suction and discharge pipes separately.
• For rear, right, and bottom piping, overlap the connection pipe heat insulation and
indoor unit pipe heat insulation and bind them with vinyl tape so that there is no
gap.
• For left and left rear piping, butt the connection pipe heat insulation and indoor unit
pipe heat insulation together and bind them with and vinyl tape so that there is no
gap.
• For left and left rear piping, wrap the area which accommodates the rear piping
housing section with cloth tape.
• For left and left rear piping, bind the connection cable to the top of the pipe with
vinyl tape.
• For left and left rear piping, bundle the piping and drain hose together by wrapping
them with cloth tape over within the range of which they fi t into the rear piping
storage section.
