Attaching the grille
(1) Close the flap.

of the grille, and reinstall the lower portion of the grille.
Fit the installation tabs into the grooves and press the
lower portion of the grille back into its original position.

3-10. Preparing the Tubing
(1) Arrangement of tubing by directions
a) Right or left tubing
The corner of the right or left frame should be cut with a
hacksaw or similar. (Fig. 3-25)
When left or right side tubing
b) Right-rear or left-rear tubing
In this case, the corners of the frame do not need to be
cut.
(2) Be sure to insulate the part of the drain hose that is run
indoors, and the refrigerant tubing.
If these are not insulated, condensation may result in
dripping and damage to walls and furniture.
The flare nuts on the 25-type (only) are large; therefore,
use the supplied insulation material.
(3) To mount the indoor unit on the rear panel.
1. When attaching the indoor unit, position the indoor unit
onto the attachment tabs on the upper part of the rear
panel. (Fig. 3-26)
2. Press on the air outlet to hold it in place, and press
the lower part of the indoor unit until a "click" sound is
heard and the indoor unit is securely fastened to the
attachment tabs on the lower side of the rear panel. (Fig.

Attachment tab
Plastic cover
(2) After performing a leak test, wrap both the refrigerant
tubing and drain hose together with insulating tape.
The drain hose should be positioned below the refrigerant
tubes, and should be given sufficient space so that no
strong pressure is applied to it.
(3) Push the wiring, refrigerant tubing and drain hose through
the hole in the wall. Adjust the indoor unit so it is securely
mounted on the rear panel.
Left or left-rear tubing
(1) Pass the tubing and drain hose into the rear of the indoor
unit. Provide sufficient length for the connections to be
made (Fig. 3-30).
Next, bend the tubing with a pipe bender, and connect
them.
