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
45, p. 35.
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".

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.
Field Installed Power Wiring
Proper Field Wiring and Grounding
Figure Required!
Failure to follow code could result in death or serious
injury.
All field wiring MUST be performed by qualified
personnel. Improperly installed and grounded field
wiring poses FIRE and ELECTROCUTION hazards. To
avoid these hazards, you MUST follow requirements
for field wiring installation and grounding as
described in NEC and your local/state/national
electrical codes.
An overall dimensional layout for the field installed wiring
entrance into the unit is illustrated in the Dimensions and
Weights chapter. To insure that the unit's supply power
wiring is properly sized and installed, follow the following
guidelines.
Verify that the power supply available is compatible with
the unit's nameplate ratings. The available supply power
must be within 10% of the rated voltage stamped on the
nameplate. Use only copper conductors to connect the
power supply to the unit.
