Note:

*1 Place indoor/outdoor unit connecting wire (A)

and power supply cord (K) at least 3 ft. (1 m)

away from the TV antenna wire.

After the leak test, apply insulating material

tightly so that there is no gap.

When the piping is to be attached to a wall

comprised of tin plate or metal netting, use

chemically treated wooden piece 25/32 in.

(20 mm) or thicker between the wall and the

piping, or wrap insulation vinyl tape 7 to 8

turns around the piping.

To use existing piping, perform COOL opera-

tion for 30 minutes and pump down before
