PIPING, DRAIN AND WIRING
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
line flare connections and the drain connection on the outside of
the wall that the fan coil is mounted on.

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.
