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. 5-28)
(2) Switch the drain hose and drain cap.
Switching drain hose and drain cap
(a) Locate the drain hose and the drain cap. (Fig. 5-29)
(b) Remove the screw fastening the drain hose on the
right side, and pull out the drain hose to remove it.
(Fig. 5-29)
(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. 5-30)
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. 5-31)
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.
