Note: Follow local codes and standards when designing duct runs to deliver the required airflow.
Minimize noise and excessive pressure drops caused by duct aspect ratio changes, bends, dampers and
outlet grilles in duct runs.

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)
ICE CEA & CGA 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
