Borders mark typical operating ranges that can be expected
for suction and discharge pressures under moderate to full
load, 44°F setpoint, with ambient air temperatures between
90-100°F. This is only a guideline and readings beyond these
ranges will occur.
Vapor entering compressor should be superheated 12-15°F.
Liquid from condenser should be subcooled 12-15°F. Econo-
mizer heat exchanger will provide up to an additional 20-28°F
of sub-cooling when in operation.
