7.3. How to connect wiring to the terminals
Caution when wiring cable
To strip off the insulation of a lead wire, always use a special tool such as a wire stripper.
If there is no special tool, carefully strip off the insulation by using a knife or other utensil.
(1) Use ring terminals with insulating sleeves as shown in the
fi
gure to connect to the
terminal block.
(2) Securely clamp the ring terminals to the wires by using an appropriate tool so that the
wires do not come loose.

(3) Connect
speci
fi
ed wires securely, and fasten them so that there is no stress applied on
the terminals.
(4) Use a screwdriver with an appropriate bit size to tighten the terminal screws. Using of
screwdriver with inappropriate bit size will damage the screw heads, and the screws
will not be tightened properly.
(5) Do not overtighten the terminal screws. Otherwise, the screws may break.

CAUTION
• Match the terminal block numbers and connection cable colors with those of the
outdoor unit or branch box. Incorrect wiring may cause a
fi
re.
• Connect the connection cables
fi
rmly to the terminal block. Imperfect installation may
cause a
fi
re.
• When
fi
xing the connection cable with the cable clamp, always fasten the cable at the
plastic jacket portion, but not at the insulator portion. If the insulator is chafed, electric
leakage may occur.
• Always connect the earth (ground) wire. Improper earthing (grounding) work can
cause electric shocks.
• Do not use the earth (ground) screw for the indoor unit to the outdoor unit unless it is
speci
fi
ed.
8. 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.
(2) Temporarily fasten the connection cable along the connection pipe with vinyl tape.
(Wrap to about 1/3 the width of the tape from the bottom of the pipe so that water
does not enter.)
(3) Fasten the connection pipe to the outside wall with a saddle, etc.
(4) Fill the gap between the outside wall pipe hole and the pipe with sealer so that rain
water and wind cannot blow in.
(5) Fasten the drain hose to the outside wall, etc.
