7.4. 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 crimp-type terminals with insulating sleeves as shown in the figure below to
connect to the terminal block.
(2) Securely clamp the crimp-type terminals to the wires using an appropriate tool so that
the wires do not come loose.
Strip: 10 mm (6/16 in.)
(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.

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 or branch box.

• Wrapping the connection pipe with cloth tape over the range within which they fi t into
the rear piping housing section.
• Fasten the pipe bracket with the screw.
(2) Fixing the pipe and conduit with cable ties.
(3) Fill the gap between the outside wall pipe hole and the pipe with sealer so that rain

(2) Does each lamp light normally?
(3) Do air fl ow direction louvers operate normally?
(4) Is the drain normal?
(5) Do not have an abnormal noise and vibration during operation?
● Do not operate the air conditioner in test run for a long time.
