CARBON MONOXIDE POISONING HAZARD
-
Special Warning for Installation of Furnace or Air Handling Units in
Enclosed Areas such as Garages, Utility Rooms or Parking Areas
Carbon monoxide producing devices (such as an automobile, space
heater, gas water heater, etc.) should not be operated in enclosed areas
such as unventilated garages, utility rooms or parking areas because of
the danger of carbon monoxide (CO) poisoning resulting from the exhaust
emissions. If a furnace or air handler is installed in an enclosed area such
as a garage, utility room or parking area and a carbon monoxide producing
device is operated therein, there must be adequate, direct outside
ventilation.
This ventilation is necessary to avoid the danger of CO poisoning which
can occur if a carbon monoxide producing device continues to operate in
the enclosed area. Carbon monoxide emissions can be (re)circulated
throughout the structure if the furnace or air handler is operating in any
mode.
CO can cause serious illness including permanent brain damage or death.

NOMENCLATURE
With the exception of “Dedicated Downflow”Air Handlers,
the models addressed in this manual may be installed in
upflow, downflow, and horizontalconfigurations.
“DEDICATED DOWNFLOW” MODELS MAY NOT BE
INSTALLED IN UPFLOW OR HORIZONTAL
CONFIGURATIONS. “Dedicated Downflow” models are
indicated by a “D” in the “Application” column. The letter
“D” appearing in any location other than that specified
in the chart above does not indicate a “Dedicated
Down-flow” model. See the chart above to verify the
nomenclatureofyourairhandler.
Air Handlers are designed for indoor use only and must
only be installed in an area protected from the elements.
DO NOT INSTALL OUTDOORS. Typical residential
installations for this product include alcoves, basements,
attics, crawl spaces, and closets. Other nonresidential
applicationsareacceptableprovidedthey comply with this
manual and local/state codes. An ARI certified rating is
available for many combinations when matched with a
GoodmanorAmana® brand condenser or heat pump.
TheAEPF models are equippedwith an ECMTM motor. An
ECMTM motoris more efficient than a standardPSC motor
andoffers features suchassoft-start,controlled off-delays,
and constant CFM. Additional features and associated
controls are discussed later in this manual.
Electric heat is available for all models as an accessory
andisnotprovidedwiththeequipment. Useonlytheelectric
heat kits identified in the “Electric Heat” section of this
manual.
AirHandlers are intended foruse with aroom thermostat.
This thermostat is not supplied with this equipment. Only

ARUF/ARPF/ADPFMOTOR
MotorSpeedAdjustment
Themotorsin allARUF,ARPFandADPFmotors are multi-
speed PSC motors. The color of the wire coming from the
motortothe“COM”terminalonthecontrolboarddefinesin
which speed the motor will operate. The black wire
representshigh speed, the red wirerepresents low speed,
and the blue wire (select models only) represents medium
speed. To change speeds, remove the wire attachedtothe
“COM” terminal on the control board, and swap it with the
wire (on terminal “M1” or “M2”) with the color that will give
thedesired speed.
NOTE: In some models, not all speed taps are allowable
for certain electric heat applications. Refer to air handler
Series and Ratings plate for minimum speed.
AEPF MOTOR
Thissectionreferencestheoperation characteristics of the
AEPFmodel motor only. TheECM control board is factory
set with dipswitch #4 in the “ON” position and all other
dipswitchesin the “OFF” position. For most applications
this setting is to be changed according to the electric
heat size and the outdoor unit selection.

TheAEPF product uses a General Electric ECMTM motor.
This motor provides many features not available on the
traditional PSC motor. These features include:
• ImprovedEfficiency
• ConstantCFM
• Soft Start and Stop
• ImprovedHumidity Control
Motor Speed Adjustment
Each ECMTM blower motor has been preprogrammed for
operationat4distinctairflowlevelswhenoperatinginCooling,
H.P.Heating,BackupHeating(ElectricHeating),andBackup
+H.P. Heating. Each modehas 4 levels todeliver different
Air Flow CFM [L/s]. The adjustment is performed by
changing the dipswitch(s) either to an “OFF” or “ON”
position.
DipswitchFunctions
TheAEPF air handler motor has an electronic control that
contains an eight (8) position dip switch. The function of
these dipswitches are shown in Table 9.
