ICE Series

Refrigeration System

Pump Down System (Remote Only)

The pump down system prevents liquid refrigerant from migrating to the evaporator and compressor during the off cycle and prevents the compressor from slugging or starting under an excessive load.

Liquid Line Solenoid

When a machine with a remote condenser shuts off, the liquid line solenoid valve, located at the outlet of the receiver, is de-energized causing the valve to close completely restricting the flow of refrigerant. The compressor will pump all of the refrigerant into the condenser and receiver.

As the system pumps down, the pressure on the low side of the system drops. When the suction pressure drops to 10 psi (.68 bar), the pump down control opens and shuts the machine off. See page F9 for pump down control operation. Liquid refrigerant is stored in the condenser and receiver while the machine is off. It is normal for the machine to pump down once or twice an hour as the pressures equalize.

When the machine comes back on (the bin switch closes or the selector switch placed to the ICE position), the liquid line solenoid valve opens and the refrigerant is released from the receiver. When the suction pressure rises to 35 psi (2.38 bar) the pump down control closes and the machine comes back on. If the machine will not pump down, the valve may not be closing all the way. A weak compressor will also prevent the machine from pumping down. Check for signs of a weak compressor before replacing the liquid line solenoid. Prior to replacing the valve, disassemble and check for obstructions that may not allow the valve to seat.

Receiver

If the system has a remote condenser, the refrigerant will enter a receiver before passing through the filter drier. The receiver holds reserve liquid refrigerant during the freeze cycle. The receiver also stores liquid refrigerant during the off cycle.
