Description

CAFC

The CAFC prevents the air conditioning coil from freezing due to low air flow, dirty filters, low

refrigerant pressure, etc. The CAFC snaps onto the suction line close to the evaporator coil as

possible and breaks the compressor circuit when the suction line drops below 36

o

F and re-

make the circuit at 46

o

F. Recommended when by-passing air into the return duct.
