Step 2 -- Mount Unit -- Before mounting the 40QNC,
QNQ unit on the wall with a walt hanging bracket, consider
how the unit will be connected to the reliigerant piping. The
indoor unit can be connected in four ways. Refer to Fig. 4 tbr
connection options. When the piping is connected to points 1, 2
or 4, relnove the kalockout either at the side or at the bottom of
the unit.
The iMoor units are mounted on the walt with a wall hang-
ing bracket. Position the wall hanging bracket so that it is tlush
with the ,a_all.See Fig. 5 for service clearances. See Fig. 6 for
walt bracket dimensions.
Complete the tbllowing when installing the wall hanging
bracket:
1. Before installing the wall hanging bracket to the wall,
relnove it tioln the indoor unit by pushing at the iMicated
pressure points at the bottom of the unit.
2. Install the walt hanging bracket in a location that is strong
enough to withstand the weight of the unit.
3. Install the walt hanging bracket so that it is level. Use a
plumb line if necessary. See Fig. 5.
NOTE: Be sure that the wall hanging bracket is level. If the
wall hanging bracket is not level, water wilt leak tiom the
indoor unit.
4. Fasten the wall hanging bracket to the wall with 4 or
more screw anchors thiough the holes near the outer edge
of the bracket.
5. Install the wall hanging bracket tlush to the wall, and
ensure the bracket does not move.
6. If the unit is relnoved tiom the wall hanging bracket after
installing it on the walt, relnove it by pushing up on the
indicated marks at the bottoln of the unit body.
Step 3 -- Complete Refrigerant Piping Con-
nections -- When running the piping for indoor units the
piping can be connected as rear piping oi side oi bottoln
piping. Refer to Fig. 4.
REAR PIPING d Route the piping behind the indoor unit so
that the piping is concealed by the unit. For rear piping installa-
tion, drill a 21/2in. diameter hole in the walt at point A or B in
Fig. 6. Drill the hole at a slope so that the outside end is lower
(1/4in. to 1/2in.) than the inside end to ensure optimal drainage.
Refer to Fig. 7. Pass the pipe through the hole.
SIDE OR BOTTOM PIPING d Relnove the kalockout in the
unit and pass the piping through the wall. The pipe should
slope downward and away ti'om the unit to ensure optimal
drainage.

ROUTING THE DRAIN HOSE AND REFRIGERANT
PIPING 6 The drain hose and drain cap are assembled as
shown in Fig. 8 in the factory. To do right-side (O), right-
bottom ((2)) or right-back (®) piping in Fig. 4 draw the drain
hose to right-side piping direction. (It is not always necessary
to exchange the location of drain hose and drain cap.)
1. Tie together the reliigerant piping, the drain hose, and the
electrical connection wire.
2. Route the refrigerant piping in the required direction, and
bend carefully avoiding pipe detbnnation.
3. Bind the drain hose and the electrical connection wire
together with thstening tape.
4. The drain hose should be at the bottom. See Fig. 9 and 10.
5. For left-hand piping, tit the pipes and the wiring into the
recess at the back of the unit.
