marks on the frame cover and dis-

engage the stationary tabs from the frame. (Fig. 7)

(3) Remove the rear panel.

Tubing can be extended in 5 directions as shown in

Fig. 8. Select the direction you need providing the

shortest run to the outside unit.

When left tubing is to be done, switch the drain

hose and drain cap. (For details, refer to “Switching

drain hose and drain cap” on page 14.)

3-2.  Make a Hole

(1) Place the rear panel from the indoor unit on the

wall at the location selected. Make sure the panel

is horizontal, using a carpenter’s level or tape mea-

sure to measure down from the ceiling. Wait until

after cutting the hole before attaching the rear

panel to the wall.

(2) Determine which side of the unit you should make

the hole for tubing and wiring. (Fig. 9) 

In the case of left-rear tubing, use the measurement

points 60 mm from the edge of the rear panel for pre-

cise placement of the hose outlet. (Fig. 9)

(3) Before making the hole, check carefully that no

studs or pipes are directly run behind the spot to

be cut.

The above precautions are also applicable if tub-

ing goes through the wall in any other location.
