process. It does not replace the detailed instructions
called out in the applicable sections of this manual.
☐ Check the unit for shipping damage and material
shortage; file a freight claim and notify appropriate
sales representative.
☐ Verify correct model, options and voltage from
nameplate.
☐ Verify that the installation location of the unit will
provide the required clearance for proper
operation.
☐ Assemble and install the roof curb (if applicable).
Refer to the latest edition of the curb installers
guide that ships with each curb kit.
☐ 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.
Factory Installed Economizer
• Ensure the economizer has been pulled out into the
operating position. Refer to the standard or low leak
economizer Installation Instructions for proper
position and setup.
• Install all access panels.

Instructions ACC-SVN178*-EN.
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 (HTB1)
in the unit control panel.
☐ Install proper grounding wires to an earth ground.
N No otte e:: All field-installed wiring must comply with NEC
and applicable local codes.
Electric Heat Requirements
• Verify that the power supply complies with the
electric heater specifications on the unit and heater
nameplate.
• Inspect the heater junction box and control panel;
tighten any loose connections.
• Check electric heat circuits for continuity.
• Low Voltage Wiring (AC and DC) Requirements.
• Install the zone thermostat, with or without
switching subbase.
• Connect properly sized control wiring to the proper
termination points between the zone thermostat
and the unit control panel.
Condensate Drain Configuration
An evaporator condensate drain connection is
provided on each unit. Refer to
“Dimensional Data,” p.
10 for the appropriate drain location.
N No otte e:: 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.
Refer to the unit Service Facts (shipped with each unit)
for filter requirements
N No otte e:: Do not operate the unit without filters.
Field Installed MERV13 Filters
Optional MERV13 filters are available for purchase.
Replace standard filters with MERV13 Filters according
to the installation instructions provided in the kit.
Field Installed Power Wiring
An overall dimensional layout for the standard field
installed wiring entrance into the unit is illustrated in
“Dimensional Data,” p. 10 . To insure the unit’s supply
power wiring is properly sized and installed, follow the
guidelines outlined below.
N No otte e:: All field installed wiring must conform to NEC
guidelines as well as state and Local codes.
Verify that the power supply available is compatible
with the unit’s nameplate ratings. The available supply
power must be within 10 percent of the rated voltage
stamped on the nameplate. Use only copper
conductors to connect the power supply to the unit.
