FHP GO024 Installation And Maintenance Manual - “Go” Models

GO SERIES
GENERAL: There are many variables (airflow, air
temperatures) in an air conditioning system that will
affect operating refrigerant pressures and
temperatures. The chart below shows approximate
conditions and is based on air flow at the rated
SCFM, entering air at 80˚ FDB, 67˚ FWB in cooling,
70˚ FBD in heating. (+) Heating data with 40˚F EFT
and lower is based on the use of an anti-freeze
solution having a freezing point 20˚F lower than the
minimum expected entering temperature.
