AIR HANDLERS
PRODUCT SPECIFICATIONS
The Whirlpool® WAHME, WAHMS, WAHMV Multi-Position Air Handlers
are suitable for use with refrigerants R-410A and replacement R22
applications.
All models feature a check flowrater expansion device and the WAHMS
features a direct-drive, multi-speed motor as well.
The WAHME’s blower design includes an EEM (energy-saving), fixed-speed
motor that can enhance the efficiency of air conditioners and heat pumps.
The WAHMV’s blower motor allows for a soft start and stop for quieter,
more efficient operation and eliminates the cold blast of air upon heating
start-up. Using an ECM™ motor, this air handler is ideal for new or retrofit
applications.

DIPSWITCH SETTINGS - WAHMV
SETTING THE MOTOR
The air handler blower motor is pre-programmed for operation
at four distinct airflow levels when operating in the Cooling,
Heat Pump heating, Backup heating (Electric Heating), and
Backup + Heat Pump heating modes. Each mode has four
levels to deliver different CFM. Simply flip the dipswitch for a
different CFM combination.

Select the taps allowed in the tables (Dipswitch 1/2/ 7/8) below.
N/A
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 thermostat or with an encoded two-stage thermostat for cooling operation.
The encoded thermostats can be used with two-stage condensing units in retrofit
applications where there aren’t enough existing wires available for connections to the
indoor thermostat and outdoor units.

Find the airflow for your application in the tables (Dipswitch 5/6/ 7/8) below. 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 settings have no effect on the set airflow.

Notes:
1) Red wires to be on transformer terminal "3" for 240 volts and on terminal "2" for 208 volts.
2) See composite wiring diagrams in installation instructions
for proper low voltage wiring connections.
3) Confirm speed tap selected is appropriate for application. If speed tap needs
to be changed, connect purple wire from terminal 4 of CR relay to appropriate tap
at TB
4) Brown and white wires are used with Heat Kits only.
