etc.), observe these requirements. To protect the
unit when brazing close to the painted surfaces,
the use of a quenching cloth is strongly advised to
prevent scorching or marring of the equipment fin-
ish.
WARNING
If this appliance is installed in an enclosed area
such as a garage or utility room with any carbon
monoxide (CO) producing appliance (i.e. automo-
bile, furnace, water-heaters, etc.), ensure the area
is properly ventilated.
WARNING
The unit MUST have an uninterrupted, unbroken
electricalgroundtominimizethepossibilityofper-
sonal injury if an electrical fault should occur. The
electrical ground circuit may consist of an appro-
priately sized electrical wire connecting the
ground lug in the unit control box to the building
electricalservicepanel. Othermethodsofground-
ing are permitted if performed in accordance with
the “National Electric Code” (NEC)/“American Na-
tional Standards Institute” (ANSI)/“National Fire
Protection Association” (NFPA) 70 and local/state
codes. In Canada, electrical grounding is to be in
accordance with the Canadian Electric Code CSA
C22.1. Failure to observe this warning can result
in electrical shock that can cause personal injury
or death.

Appliancesinstalled in garages, warehouses orotherareas
where they may be subjected to mechanical damage must
be suitably guarded against such damage by installing be-
hindprotective barriers, being elevated orlocated out of the
normalpathof vehicles. When installedona base, the base
must also be protected by similar means.
Heating and cooling equipment located in garages, which
maygenerateaglow,sparkorflamecapable of igniting flam-
mable vapors, must be installed with the ignition source at

TheAEPF air handler blowermotor is pre-programmedfor operation at fourdistinct airflow levels when operating in
the Cooling, Heat Pump heating, Backup heating (Electric Heating), and Backup + Heat Pump heating modes. Each
modes has four levels to deliver different CFM. Simply flip the dipswitch for a different CFM combination.

ON = The system operates with single-stage units using a single-stage
cooling or heat pump thermostat. (factory default)
OFF = The system operates with two-stage units with either a conventional two-stage
cooling/heat pump thermosat or with an encoded two-stage condensing unit in
retrofit applications where not enough existing wires are available for connections to
the indoor thermostat and outdoor units.
5 Cooling/Heat Pump Mode Find the airflow for your application in the tables (Dipswitch 5/6 & 7/8) below.
6 Cooling/Heat Pump Mode Set up the motor based on the outdoor unit capacity tons.
Increase or decrease your selected airflow to fit your requirement.
ON-OFF = Increases selected Cool/Heat Pump airflow by 10%
OFF-ON = Decreases selected cool/Heat Pump airflow by 15%
NOTE: Other settinghave no effect on the set airflow.
