Tubing can be extended in 3 directions as shown in Fig. 1-31. Select the direction that provides the shortest run to the outside unit.

6-11. Selecting and Making a Hole

(1)Remove the rear panel from the indoor unit and place it on the wall at the location selected. Make sure the unit is horizontal using a level gauge or tape measure to measure down from the ceiling.

1(2) Determine which side of the unit you should make the hole. (Fig. 1-32)

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

CAUTION	Also avoid areas where elec-
	trical wiring or conduits are
	located.

The above precautions are also applicable if tubing goes through the wall in any other location.

(4)Using a sabre saw, key hole saw or hole-cutting drill attachment, cut a hole in the wall. See Table 1-6 and Fig. 1-33.

(6)Place the plastic cover over the end of the pipe (for indoor side only) and insert in the wall. (Fig. 1-35)
