Horizontal to Downflow Conversion

The unit is shipped ready for horizontal duct connections.
If down flow ducts are required, the unit must be converted
following the steps below for both the supply and return
ducts.
1. Remove both horizontal duct caps.
2. Locate the duct cap inside the duct openings and remove
the screw holding it in place.
3. Lift the cap out of the unit. (Hint: The cap can be pushed
up from the bottom by reaching through the fork slot).
4. Cover the horizontal duct openings with the horizontal
duct caps. The insulation will be on the indoor side.
5. Fasten the cover with screws to seal.

Condensate Drain

Condensate is removed from the unit through the 3/4"
female pipe fitting (Figure 5) located on the front side of
the unit. Install a 2 inch condensate trap in the drain line of
the same size and prime with water. When connecting rigid
drain line, hold the female fitting with a wrench to prevent
twisting. Do not over tighten! Refer to local codes and
restrictions for proper condensate disposal requirements.
