is easily changed• WMAHV has a variable-speed ECM™ blower motor• Cooling or heat pump applications: upfl ow, down-

fl ow, and horizontal applications• WMAHM control board includes a fan delay in cool-

ing mode and is isolated from the air stream• WCC & WCH coils are equipped with a check fl ow-

rater• Cooling and Heat Pump Applications• ARI Certifi ed• ETL Listed

Cabinet Features• Painted, galvanized steel cabinet• Blower section usable as an electric furnace• Uses HKR Electric Heat Kits• Intended for use with cased evaporator coils

(WCC & WCH) and condensing units or heat pumps• Foil-faced insulation is glued in place and covers the

entire blower case to reduce operating sound and cabinet condensation

• Bottom fl anges formed inwardly for additional strength and to provide a good mounting surface for a cased-coil section to form a two-piece blower coil

The Whirlpool® WMAHM & WMAHV Modular Blowers are tailor-made for exceptional energy effi ciency. When matched with our cased coils for upfl ow, downfl ow, and horizontal applications, these two-piece blowers increase both installation and application fl exibility.
