2. Indoor Unit Installation

2-1. Fixing of Installation Plate
• Find a structural material (such as a stud) in the wall and fix installation plate (1) horizon-
tally by tightening the fixing screws (2) firmly.
• To prevent installation plate (1) from vibrating, be sure to install the fixing screws in the
holes indicated in the illustration. For added support, fixing screws may also be installed
in other holes.
• When the knockout is removed, apply vinyl tape to the knockout edges to prevent damag-
ing the wires.
• When bolts recessed in the concrete wall are to be utilized, secure installation plate (1)
using 11 × 20 · 11 × 26 oval hole (450 mm pitch).
• If the recessed bolt is too long, change it for a shorter one available in the market.
2-2. Wall Hole Drilling
1) Determine the wall hole position.
2) Drill a ø75 mm hole. The outdoor side should be 5 to
7 mm lower than the indoor side.
3) Insert wall hole sleeve (C).

You can connect indoor/outdoor lead wire without removing the front panel.
1) Open the front panel.
2) Remove wire fixture.
3) Pass indoor/outdoor unit connecting wire (A) from the back of the indoor unit and process
the end of the wire.
4) Loosen terminal screw, and connect first the earth wire, then indoor/outdoor unit con-
necting wire (A) to the terminal block. Be careful not to make mis-wiring. Fix the wire to
the terminal block securely so that no part of its core is appeared, and no external force
is conveyed to the connecting section of the terminal block.
5) Firmly tighten the terminal screws to prevent them from loosening. After tightening, pull
the wires lightly to confirm that they do not move.
6) Secure indoor/outdoor unit connecting wire (A) and the earth wire with the wire fixture.
Never fail to hook the claw of the wire fixture. Attach the wire fixture securely.
