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.
•
If the recessed bolt is too long, change it for a shorter one (field-supplied).
2=2. DRILLING
t) Determine where the holes will be located on the wall.
2) Drill a _ 3 in. (75 ram) 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.
t) 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.
t3) 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.
t6) Reinstall electrical cover.
17) Reinstall panel assembly.
