LOW PRESSURE CUT-OUT CONTROL (LPCO)

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.
