INSTALL MOUNTING PLATE
1. Carefully remove the mounting plate, which is attached to
the back of the indoor unit.
2. The mounting plate should be located horizontally and level
on the wall. All minimum spacings shown in Fig.
Fig. 7 should be maintained.
3. If the wall is block, brick, concrete or similar material, drill
.2” (5 mm) diameter holes and insert anchors for the ap-
propriate mounting screws.
4. Attach the mounting plate to the wall.

Refrigerant Line Routing
The refrigerant lines may be routed in any of the four directions
shown in Fig. 8 (a) and (b).
For maximum serviceability, it is recommended to have refrigerant

If piping is going through the back:
1. Determine pipe hole position using the mounting plate as a
template. Drill pipe hole diameter per chart below. The
outside pipe hole is 1/2-- in. (13 mm) min. lower than inside
pipe hole, so it slants slightly downward (see Fig. 9).
If piping is going to exit from the left rear, it is recommen-
ded to field --fabricate piping extensions to get the flare con-
nections to the outside of the wall.
