I. Operation Notes
The appliance utilizes a pump-down solenoid valve in the icemaker and a control
low-pressure switch in the remote condensing unit to control operation of the magnetic
contactor in the remote condensing unit. This eliminates the need for an electrical
connection between the icemaker and remote condensing unit.
Control Low-Pressure Switch Settings:
Cut-Out: 9 PSIG. Differential: 20 PSIG. Cut-In: 29 PSIG.
