Indoor Unit; Cutting The Hole In The Wall For The Connecting Piping; Installing The Wall Hook Bracket; Forming The Drain Hose And Pipe - Fujitsu AOU18RL Installation Manual

INDOOR UNIT

1.

CUTTING THE HOLE IN THE WALL FOR THE CONNECTING PIPING

(1) Cut a 3-2/16''(80 mm) diameter hole in the wall at the position shown
in (Fig.1).
(2) When cutting the wall hole at the inside of the wall hook bracket,
cut the hole within the range of the left and right center marks
3/8''(10 mm) below the installation frame.
When cutting the wall hole at the outside of the wall hook bracket,
cut the hole at least 3/8''(10 mm) below less.
(3) Cut the hole so that the outside end is lower 3/16'' to 3/8'' (5 to 10 mm)
than the inside end.
(4) Always align the center of the wall hole. If misaligned, water leak-
age will occur.
(5) Cut the wall pipe to match the wall thickness, stick it into the wall
cap, fasten the cap with vinyl tape, and stick the pipe through the
hole. (The connection pipe is supplied in the installation set.)
(Fig.1)
(6) For left piping and right piping, cut the hole a little lower so that
drain water will flow freely. (Fig.1)
2.

INSTALLING THE WALL HOOK BRACKET

(1) Install the wall hook bracket so that it is correctly positioned hori-
zontally and vertically. If the wall hook bracket is titled, water will
drip to the floor.
(2) Install the wall hook bracket so that it is strong enough to with-
stand the weight of an adult.
●
Fasten the wall hook bracket to the wall with 6 or more screws
through the holes near the outer edge of the bracket.
●
Check that there is no rattle at the wall hook bracket.
WARNING
If the wall pipe is not used, the cord interconnecting
the indoor and outdoor units may touch metal and
cause electric leakage.
3.

FORMING THE DRAIN HOSE AND PIPE

[Rear piping, Right piping, Bottom piping]
●
Install the indoor unit piping in the direction of the wall hole and
bind the drain hose and pipe together with vinyl tape. (Fig. 3)
●
Install the piping so that the drain hose is at the bottom.
●
Wrap the pipes of the indoor unit that are visible from the outside
with decorative tape.
[For Left rear piping, Left piping]
Interchange the drain cap and the drain hose.
CAUTION
(1) In order to align the drain hose and drain cap, be
sure to insert securely and vertically. Incline in-
sertion will cause water leakage.
(2) When inserting, be sure not to attach any mate-
rial besides water. If any other material is attached,
it will cause deterioration and water leakage.
(3) After removing drain hose, be sure not to forget
mounting drain cap.
(4) Be sure to fix the drain hose with tape to the bot-
tom of piping.
(5) Prevent drain water frozen under low tempera-
ture environment.
When installing indoor unit's drain hose outdoors,
necessary measure for frost protection should be
taken to prevent drain water frozen.
Under low temperature environment (when out-
●
door temperature under 32 °F), after cooling op-
eration is executed, water in the drain hose could
be frozen.
Once drain water is frozen, the drain hose will
be blocked and water leakage may be resulted
for indoor unit.
