3-38. Removing the Grille to Install the Indoor Unit

In principle, with this model wiring can be completed without removing the grille.

However, if it is necessary to change the settings on the PCB, follow the procedure below.

Removing the grille

(1)Lift up on both sides of the air-intake grille to open it. (Fig. 3-142)

(2)Remove the filter. (Fig. 3-142)

(3)Adjust the flap so that it is horizontal. (Fig. 3-143)

(4)Open the installation screw covers below the grille (3 locations). (Fig. 3-143)

(5)Remove the screws. (Fig. 3-143)

(6)Remove the grille. (Fig. 3-144)

Attaching the grille

(1)Close the flap.

(2)Keep the grille installation tabs aligned with the top portion 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 to install it.

(3)Press on the installation tabs to completely close the grille. Check that the grille and frame are fitted tightly together.

3-39. 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 hack saw or similar. (Fig. 3-145)

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 24-type (only) are large; therefore, use the supplied insulation material.
