Mounting - Sanyo CH1872 Technical & Service Manual

3-9. Mounting

(1) To install the indoor unit, mount the indoor unit onto
the 2 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. 33)
NOTE
For tubing, choose either the right or left tubing direction
and follow the steps below. This work can be made easi-
er by placing padding material (such as styrofoam) at the
rear right side of the indoor unit. (Fig. 34)
I Right-side tubing
(1) Shape the refrigerant tubing so that it can easily go
into the wall hole. (Fig. 35)
(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. 36)
(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. (See Caution on page
18.) 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. 37a)) Also,
refer to Section 5-4. Connecting Tubing between
Indoor and Outdoor Units.
(5) Assemble the refrigerant tubing, drain hose, and
conduit (including inter-unit wiring) as shown in
Fig. 37b.
