Values in bold are the minimum air flow.
Air flow ratings of 208-230 volt units are at 230v. Air flow ratings of 460 volt units are at 460 volts. Operation of units at a voltage
different from the rating point will affect air flow.

Refrigerant Cycle (Cooling Mode)
Marvair air conditioners use R-410A refrigerant in a conventional vapor-compression refrigeration cycle
to transfer heat from air in an enclosed space to the outside. A double blower assembly blows indoor
air across the evaporator. Cold liquid refrigerant passing through the evaporator is boiled into gas by
heat removed from the air. The warmed refrigerant gas enters the compressor where its temperature
and pressure are increased. The hot refrigerant gas condenses to liquid as heat is transferred to outdoor
air drawn across the condenser by the condenser fan. Liquid refrigerant is metered into the evaporator
