*Based on 15% Methanol antifreeze solution
Operating Pressure/Temperature tables include the
following notes:
• Airflow is at nominal (rated) conditions;
• Entering air is based upon 70°F [21°C] DB in heating
and 80/67°F [27/19°C] in cooling;
• Subcooling is based upon head pressure at
compressor service port;
• Cooling air and water values can vary greatly with
changes in humidity level.
