1. Specifications
6-53. Left-side tubing
(1) Lead the tubing and drain hose through the wall, allowing
sufficient length for connection. Then bend the tubing using a
tube bender to make the attachment. (Fig. 1-171)
(2) Switch the drain hose and drain cap.
Switching drain hose and drain cap
(a) Locate the drain hose and the drain cap. (Fig. 1-172)
(b) Remove the screw fastening the drain hose on the right
side, and pull out the drain hose to remove it.
(Fig. 1-172)
(c) Apply moderate force to pull off the drain cap on the left
side. (If you cannot pull it off by hand, use a long-nose
pliers.)
(d) Reattach the drain hose to the left side and the drain
cap to the right side. (Fig. 1-173)
Drain hose
Slide the drain hose fully onto the drain pan outlet. (It will
be easy to slide when water is added.) Check that the
screw holes in the drain bracket and the drain pan outlet
are aligned and securely in contact, then fasten them with
the screw. (After attaching the drain hose, check that it is
attached securely.) (Fig. 1-174)
Drain cap
Use a Phillips head screwdriver to push the drain cap in
firmly. (If it is difficult to push in, wet the cap with water first.)
(3) Install the indoor unit on the rear panel.
(4) Connect the tubing and wiring led inside from outdoors.
(5) After completing a leak test, bundle the tubing together with
armoring tape and store it inside the tubing storage area at
the back of the indoor unit and hold it with clamps. (Figs.
1-173 and 1-175)

(1) Remove the screw cover on the bottom surface.
(Fig. 1-176)
(2) Fasten the frame to the rear panel using the 2 supplied
tapping screws 5/32 × 13/32" (4 × 10 mm). (Fig. 1-176)
(3) Press the 2 marks on the lower part of the indoor unit
and unlatch the tabs. Then lift the indoor unit and unmount.
(Fig. 1-177)
NOTE
Under normal conditions, the installation design calls for a
less than 2 mm gap between the air conditioner unit and the
wall.
Confirm that the gap is appropriate (less than 5/64" (2 mm)).
6-54. Drain Hose
a) The drain hose should be slanted downward to the
outdoors. (Fig. 1-178)
b) Never form a trap in the course of the hose.
c) If the drain hose will run in the room, insulate the hose with
insulation* so that chilled condensation will not damage
furniture or floors. (Fig. 1-179)
*Foamed polyethylene or its equivalent is recommended.
WARNING
Do not supply power to the
unit or operate it until all
tubing and wiring to the
outside unit are completed.
