Typical Electrical Wiring Unit Voltage
UNIT VOLTAGE
The unit transformer is factory connected for 230V operation.
If the unit is to operate on 208V, reconnect the transformer
primary lead as shown on the unit wiring diagram.
HEAT A NTICIPATOR S ETTING
The heat anticipator is to be set by measuring the load
(amperage) at the “R” circuit. Follow the instructions provided
by the thermostat for more details.
CIRCULATING AIR AND FILTERS
AIRFLOW CONVERSION
Units can easily be converted from horizontal to down-
discharge airflow delivery. In down-discharge or high static
installations, the installer should measure the total external
static and review the blower performance charts before
performing the installation. In some installations it will be
necessary to change the blower speed to provide proper air
flow.
Horizontal Air Flow
Single phase models are shipped without horizontal duct
covers. If needed, these kits may be ordered through
Goodman’s Service Parts department.
For 3-phase models only, remove supply and return duct
covers which are attached to the unit as shown below.

Duct Cover Installation
Down Discharge Applications
Cut insulation around bottom openings and remove panels
from the bottom of the unit, saving the screws holding the
panels in place.
NOTE: Single phase models require installation of horizontal
duct kit #20464501PDGK (medium chassis) and
#20464502PDGK (large chassis).
DUCTWORK
Duct systems and register sizes must be properly designed
for the C.F.M. and external static pressure rating of the unit.
Ductwork should be designed in accordance with the
recommended methods of Air Conditioning Contractors of
America Manual D (Residential) or Manual Q (Commercial).
All ductwork exposed to the outdoors must include a
weatherproof barrier and adequate insulation.
A duct system should be installed in accordance with
Standards of the National Board of Fire Underwriters for the
Installation of Air Conditioning, Warm Air Heating and
Ventilating Systems. Pamphlets No. 90A and 90B.
