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. 3 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
appropriate mounting screws.
4. Attach the mounting plate to the wall.

PIPING, DRAIN AND WIRING
Refrigerant Line Routing
The refrigerant lines may be routed in any of the four directions
showninFig.9.
For maximum serviceability, it is recommended to have refrigerant
line flare connections and the drain connections on the outside of
the wall that the fan coil can be mounted on.
If piping is going through the back:
1. Determine the pipe hole position using the mounting plate
as a template. Drill pipe hole diameter per values given in
Fig. 4 through 7. The outside pipe hole is 1/2--in. (13 mm)
min. lower than inside pipe hole, so it slants slightly
downward (see Fig. 8).
