6-14. Removing the Wall Fixture from the Unit
Remove the set screws and take off the rear panel.
(Fig. 1-64)
NOTE
Tubing can be extended in 3 directions as shown in
Fig. 1-65. Select the direction that provides the shortest
run to the outside unit.
6-15. 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.
(2) Determine which side of the unit you should make
the hole. (Fig. 1-66)
(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
1-10 and Fig. 1-67.
Table 1-10
(5) Measure the thickness of the wall from the inside
edge to the outside edge and cut PVC pipe at a
slight angle 1/4" shorter than the thickness of the
wall. (Fig. 1-68)
(6) Place the plastic cover over the end of the pipe
(for indoor side only) and insert in the wall.
