Suct: 000 to 650 psi pressure range of
gauge
Disc: 000 to 650 psi
COMPRESSOR SET POINT
HIGH DISCHARGE PRESS
Shutoff: 600 psi Compressor will lock
out at this pressure
COMPRESSOR SET POINT
LOW SUCTION PRESS
Shutoff: 025 psi Compressor will lock
out if suction drops to
this pressure
COMP A -- CYCLE OFF LOW TEMPERATURE
