NOTE
For tubing, choose either the right or left tubing direction and
follow the steps below. This work can be made easier by
placing padding material (such as styrofoam) at the rear right
side of the indoor unit. (Fig. 3-59)
Fig. 3-59
■ Right-side tubing
(1) Shape the refrigerant tubing so that it can easily go into the
wall hole. (Fig. 3-60)
Fig. 3-60
(2) Push the wiring, refrigerant tubing, and drain hose through
the hole in the wall. Adjust the indoor unit so it is securely
seated on the rear panel. (Fig. 3-61)
Fig. 3-61
(3) Carefully bend the tubing (if necessary) to run along the
wall in the direction of the outdoor unit and then tape as far
as the fittings. The drain hose should come straight down
the wall to a point where water runoff won’t stain the wall.
(4) Connect the refrigerant tubing to the outdoor unit. (After
performing a leak test on the connecting part, insulate it
with the tubing insulation. (Fig. 3-62)
Fig. 3-62
(5) Assemble the refrigerant tubing, drain hose, and inter-unit
wiring as shown in Fig. 3-62.
■ 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. 3-63)
Fig. 3-63
(2) Switch the drain hose and drain cap.
Switching drain hose and drain cap
(a) Locate the drain hose and the drain cap. (Fig. 3-64)
Fig. 3-64
(b) Remove the screws fastening the drain hose on the
right side, and pull out the drain hose to remove it.
(Fig. 3-64)
(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. 3-65)
