NOMENCLATURE
With the exception of “Dedicated Downflow” Air Handlers,
the models addressed in this manual may be installed in
upflow, downflow, and horizontal configurations.
“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
nomenclature of your air handler.
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
applications are acceptable provided they comply with this
manual and local/state codes. An ARI certified rating is
available for many combinations when matched with a
Goodman or Amana® brand condenser or heat pump.
The AEPF models are equipped with an ECM
TM
motor. An
ECM
TM
motor is more efficient than a standard PSC motor
and offers features such as soft-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
and is not provided with the equipment. Use only the electric
heat kits identified in the “Electric Heat” section of this
manual.
Air Handlers are intended for use with a room thermostat.
This thermostat is not supplied with this equipment. Only
thermostats that use 24 VAC operating voltage can be used.
UNIT INSPECTION
Upon delivery, inspect the unit for damage. Any damage
must be reported immediately to the carrier. Do not install
this equipment if it is determined that the integrity or safety
has been compromised by freight damage.
Using the table “Model Identification” section, check the
equipment model number to ensure the unit is appropriately
sized for the condenser unit.
