Mounting
(1) To install the indoor unit, mount the indoor unit onto the 3
tabs on the upper part of the rear plate.
(2) Hold down the air discharge outlet and press the lower part
of the indoor unit until it clicks to securely fasten to the 2
tabs on the lower part of the rear plate. (Fig. 4-22)
NOT E
For tubing, choose either the right or left tubing direction and
follow the steps below. Also, extend the support on the back of
the indoor unit as a stand to make your work easier. (Fig. 4-23)
Right-side tubing
(1) Shape the refrigerant tubing so that it can easily go into the
wall hole. (Fig. 4-24)
(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. 4-25)
(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. 4-26)).
(5) Assemble the refrigerant tubing, drain hose, and conduit
(including inter-unit wiring) as shown in Fig. 4-27.
