3. How to Install the Indoor Unit
Remove and discard the set screws and take off the rear panel. (Fig. 6)
NOTE
Tubing can be extended in 3 directions as shown in Fig. 7a. Select the direction you need providing the shortest run to the outside unit.
(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 carpenter’s level or tape measure to measure down from the ceiling.
(2)Determine which side of the unit you should make the hole. (Fig. 7b)
(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 electri- | |
cal 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
