☐
Fabricate and install ductwork; secure ductwork to
curb.
☐
Rigging the unit.
☐
Set the unit onto the curb; check for levelness.
☐
Ensure unit-to-curb seal is tight and without buckles or
cracks.
☐
Install and connect a condensate drain line to the
evaporator drain connection.
Main Electrical Power Requirements
☐
Verify that the power supply complies with the unit
nameplate specifications.
☐
Inspect all control panel components; tighten any loose
connections.
☐
Connect properly sized and protected power supply
wiring to a field-supplied/ installed disconnect switch
and to the main power terminal block in the unit control
panel.
☐
Install proper grounding wires to an earth ground.
Note:
All field-installed wiring must comply with NEC and
applicable local codes.
External Vent Hood Installation
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.
1. Remove and discard the cover plate located on the gas
heat panel.
Important:
•
Make sure you read the label located
on the cover plate before you discard
it.
•
Do not discard the fastening screws!
They will be needed to install the vent
hood.
2. Locate the vent hood behind the panel, along the base
of the unit.
3. Install the vent hood on the gas heat panel using the
screws removed in Step 1. Make sure it is properly
secured to the panel.

Condensate Drain Configuration
An evaporator condensate drain connection is provided on
each unit. Refer to
for the
appropriate drain location.
Note:
Use 1-inch PVC pipe to connect to the drain pan
outlet provided in the unit. This is a slip fit joint (no
threads). Do not use PVC glue to connect
condensate drain, thread sealing compound or
Teflon tape may be used.
A condensate trap must be installed at the unit due to the
drain connection being on the “negative pressure” side of
the fan.
A condensate drain line must be connected to the P-Trap.
Pitch the drain lines at least 0.5-inch for every 10 feet of
horizontal run to assure proper condensate flow. Do not
allow the horizontal run to sag causing a possible
doubletrap condition which could result in condensate
backup due to “air lock”.
Filter Installation
Each unit ships with 2-inch filters installed. 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
An overall dimensional layout for the standard field
installed wiring entrance into the unit is illustrated in
. To insure the unit’s supply power
wiring is properly sized and installed, follow the guidelines
outlined below.
