2. INDOOR UNIT INSTALLATION
2- 1. ATTACHING THE INSTALLATION PLATE
Find a stud in the wall to attach installation plate (1) horizontally on the wall with screws (2).
*
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 4 in. (44 mm
* 20 mm - 14 mm
x
26 mm) oval hole (17-3/4 in. [450 mm] pitch).
*
Ifthe recessed bolt is too long, change it for a shorter one (field-supplied).
2-2. DRILLING
1) Determine where the holes will be located on the wall.
2) Drill a @ 2-9/16 in. (65 mm) hole. The outdoor side should be 6/32 to 9/32 in. (6 te 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.
Remove the panel assembly. (Refer to 5-1.)
Place the upper part of the indoor unit on the installation plate.
Remove corner box and conduit cover.
Attach conduit pipe (for rear piping) / elbow joint (for right, left, or downward
piping) to
conduit cover 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)
5) Process
the end of ground wire (Fig. 3). Connect it to the ground terminal of electrical
parts box.
6) 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.
7) Firmly tighten the terminal screws. After tightening, verify that the wires are tightly fas-
tened.
8) Secure indoor/outdoor unit connecting wire (A) and the ground wire with conduit cover.
Never fail to hook the claw of the conduit cover to the electrical box. Attach the conduit
cover securely. (Fig. 4)
9) According to the piping direction, remove the shaded
part of the left side of box (Fig. 5)
or corner box (Fig.6). Reinstall corner box and front panel.
