toward the outside.

4/5 in (20 mm) for the drain pipe.
2)The drain hose (outer diameter 5/7 in (18 mm) at connecting end, 8 2/3 in (220 mm) long)is supplied with the indoor
unit. Prepare the drain pipe picture below position.
3)The drain pipe should be inclined downward so that water will flow smoothly without any accumulation.(Should not
