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”.

Filter Installation
The quantity of filters is determined by unit size. Access to
the filters is obtained by removing the filter access panel.
Refer to the unit Service Facts (shipped with each unit) for
filter requirements.
Note:
Do not operate the unit without filters.
Field Installed Power Wiring
WARNING
Proper Field Wiring and Grounding
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 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.
NOTICE
Use Copper Conductors Only!
Failure to use copper conductors could result in
equipment damage as unit terminals are not designed
to accept other types of conductors.
Important:
If the unit is not equipped with an optional
factory installed non-fused disconnect
switch or circuit breaker, a field supplied
disconnect switch must be installed at or
near the unit in accordance with the
National Electrical Code (NEC latest
edition).

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.
Standard Wiring
Location of the applicable electrical service entrance is
illustrated in the Dimensions and Weights chapter.
Complete the unit’s power wiring connections at
Compressor Contactor # 1 (CC1) inside the unit control
panel. Refer to the customer connection diagram that is
shipped with the unit for specific termination points
Provide proper grounding for the unit in accordance with
local and national codes.
