discharge pressure at the selected setpoint anytime the
compressor is operating.
Set Pressure Setpoint
The pressure setpoint should be adjusted to 250 psig
initially. When the ambient temperature is above 50°F
(10°C), the outdoor fan motor will be energized
continuously. When the ambient temperature is below
50°F, the pressure sensor reading is used to switch the
motor on or off. When the pressure is 15psi below the
set pressure the motor will be turned off. When the
pressure is 15psi above the set pressure, the motor will
be turned on.
After completion of installation and pressure setting
adjustment), reinstall the compressor and control box
access panels and secure with screws that were
removed.
Reconnect all power to the unit. Refer to
troubleshooting guide, if needed.
