When matched with a Goodman or Amana brand
condenser or heat pump, an ARI certified rating is available
for many combinations.
The AEPT 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 the associated
controls are discussed later in this manual.
Electric heat is available for all models. This is an accessory
and is not provided with the equipment. Use only the
electric heat kits identified in the “Electric Heat” section of
this manual.
These 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.
If an incorrect unit is supplied, it must not be installed and
it is to be returned to the supplier. The manufacturer
assumes no responsibility for the installation of incorrectly
delivered units.
The evaporator coil contains a high-pressure inert gas
holding charge.
ELECTRIC HEAT
WARNING
REFER TO THE “INSTALLING ELECTRIC HEAT” SECTION
OF THIS MANUAL AND THE INSTRUCTIONS PROVIDED
WITH THE HEAT KIT FOR THE CORRECT INSTALLATION
PROCEDURE.
WARNING
THE ELECTRICAL CHARACTERISTICS OF THE AIR
HANDLER, THE ELECTRIC HEAT KIT, AND THE SUPPLY
POWER MUST AGREE, UNLESS USING HKR3 (3 PHASE)
SERIES HEAT KIT. THIS AIR HANDLER DOES NOT HAVE
FACTORY INSTALLED ELECTRIC HEAT. ELECTRIC
HEAT IS AVAILABLE AS AN ACCESSORY. IF INSTALLING
THIS OPTION, THE ONLY HEAT KITS THAT CAN BE USED
ARE THE HKR SERIES AS INDICATED BELOW: NOTE:
THE AMANA BRAND EHK, ECB, EDB, AND EDK KITS ARE
NOT APPROVED FOR USE WITH THESE AIR
HANDLERS.
The heating mode temperature rise is dependent upon the
system airflow, the supply voltage, and the heat kit size
(kW) selected. Use Tables 1-3 to determine the
temperature rise (
o
F).

Note: For installations not indicated above the following
formula is to be used:
TR = (kW x 3412) x (Voltage Correction) x 1.08 / CFM
Where: TR = Temperature Rise
KW = Heater Kit Actual kW
3412 = Btu per kW
Voltage Correction =.96 (230 Supply Volts)
=.92 (220 Supply Volts)
=.87 (208 Supply Volts)
1.08 = Constant
CFM = Measured Airflow
NOTE: The Temperature Rise Tables can also be used to
determine the air handler airflow delivery. When using
these tables for this purpose set the room thermostat to
