*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.
