A 3/4-inch female NPT condensate drain connection is pro-
vided on the evaporator access panel end of the unit. See
Figure 4. Provide a trap and fill it with water before starting the
unit to avoid air from being drawn through. Follow local codes
and standard piping practices when running the drain line.
Pitch the line downward away from the unit. Avoid long
horizontal runs. See Figure 13.
NOTE: Do not use reducing fittings in the drain lines. The
condensate drain must be:
●
Made of 3/4" pipe size.
●
Pitched 1/4" per foot to provide free drainage to
convenient drain system.
●
Trapped.
●
Must not be connected to closed drain system.
