Operation Function

9-5) Ice & Water Dispenser Function

●Among several ice-maker functions, the ice extraction function is performed by mechanical system. Only the relay control for a cubed-ice dispensing and the SSR control for the ice chute door are performed electronically.

1) Select Cubed/Crushed/Ice-off function

1-1) The Ice Type button selects Cubed/Crushed/Ice-off options in sequence.

1-2) A default setting is Cubed option.

1-3) If Cubed ice is selected, the Crushed ice bypass solenoid and the geared motor will allow Cubed ice to by pass the ice Crusher.

1-4) If Ice-off is selected, the ice maker will stop working. This option will be terminated when Cubed and Crushed options are selected.

Note) When the Ice-off indicator is on and the remained ice is in tray, only Cubed ice will be dispensed from the ice bucket.

1-5) The ice chute door must be open for 5 seconds after dispensing ceases. After this 5 seconds delay, SSR will be controlled to shut the ice chute door.

Note) Do not force to close the ice chute door. Try to dispense some more ice again to work it automatically.

2) Water Dispenser function

2-1) To dispense water, depress the water dispenser lever located in the dispenser recess.

2-2) When the lever is depressed, the water solenoid valve located in the machine compartment is open to flow water.

2-3) There is no electronic control function for this option.

9-6) C-Fan Motor Delay Function of the Machine Compartment

●According to the ambient temperature, the condenser fan located in the machine compartment is operated with different modes.

		Ranges of ambient temp.	Operation
	C-FAN	Above 66℉	C-FAN is ON as soon as the compressor is on.
		61℉ ~ 65℉	C-FAN is ON with 5 minutes delay from the compressor on.
	Delay function
		Below 60℉	C-FAN is OFF regardless of the compressor operation.

9-7) CoolSelect ZoneTM Function (RS2666,RS2777)

●To select this function, open the refrigerator door and press the button on the control panel of CoolSelect Zone TM drawer.

●When the CoolSelect ZoneTM function is selected, the damper inside fan ductwork is open. So the refrigerator cooling is performed first, then the damper is closed to control the CoolSelect ZoneTM temperature.
