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 hori- zontal, using a carpenter’s level or tape measure to measure down from the ceiling. Wait until after cut- ting 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. 9a or 9b)

NOTE

In the case of left-rear tubing, use the measurement points from the edge of the rear panel for precise place- ment of the hose outlet. (Fig. 9a or 9b)

(3)Before making the hole, check carefully that no studs or pipes are directly run behind the spot to be cut.
