2-2. DRILLING
1) Determine where the holes will be located on the wall.
2) Drill a ø 3 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:
When the indoor unit is powered from the outdoor unit, depending on local code, a discon-
nect switch needs to be installed to a power supply circuit.
1) Open the front panel.
2) Place the upper part of the indoor unit on the installation plate.
3) Remove electrical cover.
4) Remove VA clamp.
5) Remove corner box.
6) Remove cable guide.
7) Remove conduit plate.
8) Attach conduit pipe (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 appear-
ing 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)
9) Process the end of ground wire (Fig. 3). Connect it to the ground terminal of electrical
parts box.
10) 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.
11) Firmly tighten the terminal screws. After tightening, verify that the wires are tightly fas-
tened.
12) Reinstall conduit plate.
13) Reinstall cable guide.
14) According to the piping direction, remove the shaded part of the left side of box (Fig.4)
or corner box (Fig. 5).
15) Reinstall VA clamp.
16) Reinstall electrical cover.
17) Reinstall panel assembly.
