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 fl owrater expansion device and the WAHMS features a direct-drive, multi-speed motor as well. The WAHME’s blower design includes an EEM (energy-saving), fi xed-speed motor that can enhance the effi ciency of air conditioners and heat pumps.The WAHMV’s blower motor allows for a soft start and stop for quieter, more effi cient operation and eliminates the cold blast of air upon heating start-up. Using an ECM™ motor, this air handler is ideal for new or retrofi t applications.

DIPSWITCH SETTINGS - WAHMVThe air handler blower motor is pre-programmed for operation at four distinct airfl ow 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 fl ip the dipswitch for a different CFM combination.

1 Electric Heat ModeSelect the taps allowed in the tables (Dipswitch 1/2/ 7/8) below.

2 Electric Heat Mode

3 N/A N/A

4 Thermostat Mode

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 cool-

ing/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 retrofi t

applications where there aren’t enough existing wires available for connections to the

indoor thermostat and outdoor units.

5 Cooling/Heat Pump Mode Find the airfl ow for your application in the tables (Dipswitch 5/6/ 7/8) below. Set up the

motor based on the outdoor unit capacity tons.6 Cooling/Heat Pump Mode

7 Trim CFM Adjust Mode Increase or decrease your selected airfl ow to fi t your requirement.

ON-OFF = Increases selected Cool/Heat Pump airfl ow by 10%.

OFF-ON = Decreases selected Cool/Heat Pump airfl ow by 15%

Note: Other settings have no effect on the set airfl ow.8 Trim CFM Adjust Mode
