HARVEST PRESSURE REGULATING (HPR)
SYSTEM REMOTE CONDENSER ONLY
GENERAL
The harvest pressure regulating (HPR) system
includes:
• Harvest pressure regulating solenoid valve (HPR
solenoid). This is an electrically operated valve
which opens when energized, and closes when
de-energized.
• Harvest pressure regulating valve (HPR valve).
This is a pressure regulating valve which
modulates open and closed, based on the
refrigerant pressure at the outlet of the valve. The
valve closes completely and stops refrigerant flow
