• Connect wires to the appropriate terminals
• For future servicing, leave some slack in the connecting wires.
• Make ground wire a little longer than oth-
ers. (More than 1-9/16 in. [40 mm])

• To prevent installation plate (1) from vibrating, be sure to install the attachment screws in
the holes indicated in the illustration. For added support, additional screws may also be
installed in other holes.
• When the indoor unit is to be attached to a concrete wall using recessed bolts, secure
installation plate (1) using 7/16 in. x 13/16 in. · 7/16 in. x 1 in. (11 mm × 20 mm · 11 mm ×
26 mm) oval hole (17-3/4 in. [450 mm] pitch).

2-2. DRILLING
1) Determine where the holes will be located on the wall.
2) Drill a ø3 in. (75 mm) hole. The outdoor side should be 6/32 to 9/32 in. (5 to 7 mm) lower
than the indoor side.
3) Insert wall hole sleeve (C).
2-3. CONNECTING WIRES FOR INDOOR UNIT
Note:
The unit should be installed by a licensed contractor/electrician. If required by applicable
national, state and local codes; a disconnect switch will need to be installed when the
indoor unit is powered from the outdoor unit.
1) Remove the panel assembly. (Refer to 5-1.)
2) Place the upper part of the indoor unit on the installation plate.
3) Remove corner box and electrical cover.
4) Remove display and i-see sensor assembly, conduit cover and conduit plate.
5) Attach straight joint (for rear piping) / elbow joint (for right, left, or downward piping) to
conduit plate with lock nut. The thread of the installed conduit pipe / elbow joint appearing
inside should be less than 3/8 in. (10 mm). (Fig. 1) Elbow joint should appear less than
1-3/16 in. (30 mm) outside. (Fig. 2)
6) Process the end of ground wire (Fig. 3). Connect it to the ground terminal of electrical parts
box.
7) Process the end of indoor/outdoor unit connecting wire (A) (Fig. 3). Attach it to the terminal
block. Be careful not to make mis-wiring. Attach the wire to the terminal block securely so
that its core cannot be seen, and no external force affects the connecting section of the
terminal block.
8) Firmly tighten the terminal screws. After tightening, verify that the wires are tightly fastened.
9) Reinstall conduit plate, conduit cover and display panel.
10) According to the piping direction, remove the shaded part of the corner box L (Fig. 4) or
corner box R (Fig. 5). Reinstall electrical cover, corner box R and front panel.
Less than 3/8 in.
