Condensate Drain Configuration
WARNING
Hazardous Voltage!
Failure to disconnect power before servicing could
result in death or serious injury.
Disconnect all electric power, including remote
disconnects before servicing. Follow proper lockout/
tagout procedures to ensure the power can not be
inadvertently energized. Verify that no power is
present with a voltmeter.
An evaporator condensate drain connection is provided on
each unit. Refer to the ductwork section in the Installation
chapter for the appropriate drain location.
The 6 to 12.5 tons condensate drain pan is convertible.
Refer to the ductwork section in the Installation chapter for
the drawings. It can be converted to drain condensate out
the front side of the unit or through the base.
To convert drain condensate out the front of unit:
1.
Remove evaporator access panel and supply air
access panels.
2.
Remove the support panel that the condensate drain
pan exits through.
3. Slide the condensate drain pan out of the unit and
rotate 180°.
4. Slide the condensate drain pan back into the unit, align
the drain with the grommeted opening in the rear
support panel and push until the coupling is seated in
the grommet.
5. Replace the front support panel by aligning the panel
with tabs in the raceway. Align the condensate drain
pan support in the grommeted hole as the panel is put
in place.
6. Replace evaporator access panel and supply air
access panels.
To convert drain condensate through the base of unit:
1. Remove evaporator access panel and supply air
access panels.
2. Remove the support panel that the condensate drain
pan exits through.
3. Slide the condensate drain pan out of the unit.
4. Place on a level surface in the position it was removed
from the unit.
5. Remove the plug knockout in the bottom of the
drainpan to convert it to through the base drainage.
6. Plug the original condensate drain opening with a field
supplied 3/4” NPT plug.
7. Slide the condensate drain pan back into the unit, align
the drain support with the grommeted opening in the
rear support panel and push until the support is seated
in the grommet.
8. Replace the front support panel by aligning the panel
with tabs in the raceway. Align the plugged condensate
drain pan coupling in the grommeted hole as the panel
is put in place.
9. Replace evaporator access panel and supply air
access panels.
A condensate trap must be installed at the unit due to the
drain connection being on the “negative pressure” side of
the fan. Install the P-Trap using the guidelines in
.
A condensate drain line must be connected to the P-Trap.
Pitch the drain lines at least 1/2 inch for every 10 feet of
horizontal run to assure proper condensate flow. Do not
allow the horizontal run to sag causing a possible double
trap condition which could result in condensate backup due
to “air lock”.

Note:
Minimum if unit static is higher trap must be taller to
drain appropriately.
Filter Installation
The quantity of filters is determined by unit size. Access to
the filters is obtained by removing the filter access panel.
Note:
Do not operate the unit without filters.
