Part Number 80-1230-9 10/10 169
QF2200 Only
LOW PRESSURE CUT-OUT CONTROL
RFC2085 (QF2200) Only
FUNCTION
Energizes and de-energizes the contactor coil when
suction pressure rises above or falls below setpoint.
The LPCO control is closed at pressures above
setpoint and opens at pressures below setpoint.
SPECIFICATIONS
CHECK PROCEDURE
1. Connect manifold gauges at suction and
discharge access valves at the condensing unit.
2. Set ICE/OFF/CLEAN switch to OFF.
3. The liquid line solenoid valve will de-energize and
the suction pressure will begin to decrease. The
low-pressure control will open at the listed
specification.
4. Use the manifold gauge set to increase suction
pressure. Feed refrigerant from the high side
access valve to the low side access valve. Add
refrigerant in small increments to allow the low
side pressure to be monitored. The low pressure
control will close at the listed specification.
Replace the LPCO control if it:
• Will not close at the specified set point.
• Does not open at the specified set point.
