†. Required filter sizes shown are based on the larger of the AHRI (Air Conditioning Heating and Refrigeration Institute) rated cooling airflow or the heating airflow velocity of
300 to 350 ft/minute for throwaway type. Air filter pressure drop for non-standard filters must not exceed 0.08 IN. W.C.
If using accessory filter rack refer to the filter rack installation instructions for correct filter sizes and quantity.

Step 6 – Connect Condensate Drain
NOTE: When installing condensate drain connection be sure to comply
with local codes and restrictions.
This unit disposes of condensate water through a 3/4 in. NPT fitting
which exits through the base on the evaporator coil access side. See
Fig. 3
-
Fig. 6
for location.
Condensate water can be drained directly onto the roof in rooftop
installations (where permitted) or onto a gravel apron in ground level
installations. Install a field-supplied 2-in. (51 mm) condensate trap at the
end of condensate connection to ensure proper drainage. Make sure that
the outlet of the trap is at least 1 in. (25 mm) lower than the drain-pan
condensate connection to prevent the pan from overflowing (See
Prime the trap with water. When using a gravel apron, make sure it
slopes away from the unit.
Connect a drain tube using a minimum of 3/4-in. PVC or 3/4-in. copper
pipe (all field-supplied) at the outlet end of the 2-in. (51 mm) trap. Do
not undersize the tube. Pitch the drain tube downward at a slope of at
least 1-in. (25 mm) for every 10 ft (3.1 m) of horizontal run. Be sure to
check the drain tube for leaks.
Manufacturer reserves the right to change, at any time, specifications and designs without notice and without obligations.
