DRILL A HOLE IN WALL FOR INTERCONNECTING
PIPING, DRAIN AND WIRING

For maximum serviceability, it is recommended that you have
refrigerant line flare connections and the drain connections on the
outside of the wall that the fan coil can be mounted on.

1. Determine the pipe hole position.
2. Drill the pipe hole. The outside pipe hole is 1/2−in. (13 mm)

lower than the inside pipe hole, so it slants slightly downward
(see Fig. 8).
