NOTE

Tubing can be extended in 4 directions as shown in Fig. 3-134. Select the direction which will provide the shortest run to the outdoor unit.

3-36. Selecting and Making a Hole

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

(2)Determine which notch of the rear panel should be used. (Fig. 3-135)

(3)Before drilling a hole, check that there are no studs or pipes behind the determined location. 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 attach-

Kment, make a hole (dia. 3-5/32") in the wall. (Fig. 3-136)

(5)Measure the thickness of the wall from the inside edge to the outside edge and cut the PVC pipe at a slight angle 15/64" shorter than the thickness of the wall. (Fig. 3-137)

(6)Place the plastic cover over the end of the pipe (for indoor side only) and insert in the wall. (Fig. 3-138)

NOTE

The hole should be made at a slight downward gradient to the outside.

CAUTION Avoid areas where electrical wiring or conduits are located.

3-37. Installing the Rear Panel onto the Wall

Confirm that the wall is strong enough to support the unit. See either Item a) or b) below depending on the wall type.
