Caution

To avoid personal injury or property damage, observe following instructions:

• Do not operate dispenser with Deepfreeze® door open.

• Do not put fingers, hands, or any foreign object into dispenser opening.

• Do not use sharp objects to break ice.

Water Dispenser Operation

It takes approximately 1 minute after initially pressing dispenser bar before water dispenses after initial connection of water supply . Discard first 10 to 14 containers of water after initially connecting refrigerator to household water supply and after extended periods of non-use.

• Dispense water by pressing sturdy wide mouthed container against water dispenser bar.

• Stop water dispensing by releasing pressure on bar. A small amount of water may continue to fall. Spill shelf is not self-draining. Large spills should be wiped dry.

Ice Dispenser Operation

• Select cubed or crushed mode by sliding lever on dispenser panel. Dispense ice by pressing wide mouthed container against ice dispenser bar.

Important Reduce spraying of crushed ice by holding wide mouthed container directly under ice chute and as high as possible in dispenser area.

• Stop ice dispensing by releasing pressure on bar before container is full. Some ice will continue to fall. Do not remove container until last of ice falls.

If dispensing ice continuously , dispenser motor is designed to shut off after 3 to 5 minutes. Motor resets after 3 minutes and dispensing can continue.

A slight delay occurs when switching between cubed and crushed modes. Pieces of crushed ice will vary in size and shape. "Snow" may form on door and ice chute when repeatedly dispensing crushed ice. Allow "snow" to evaporate or wipe dry .

Dispenser operates only with cubes of proper size and crescent shape. Do not add purchased ice cubes or other shaped cubes to ice bucket.

Removing Ice Bucket

• Remove ice bucket by lifting bucket and pulling out.

• Replace ice bucket by sliding in until bucket locks in place. Ice bucket must be locked in place for proper ice dispensing. If Deepfreeze® door does not close, bucket is not in proper location.

An open thermistor or thermistor circuit will result in failure of refrigerator to cool.

Shorted thermistor will cause refrigerator to run 100 percent of time except for defrost.

• Freezer temperature setting and thermistor value will determine if compressor/condenser fan and evaporator fan switches are open or closed. Compressor/condenser fan switch must be open for 6 minutes before switch can close again (compressor dwell time).

• Cut-out and cut-in temperature values must be reached and maintained for 15 seconds before output state will change (digital delay).

• Refrigerator and freezer control calibration can be adjusted in Program Mode B.

Electronic Functional Description

Adaptive Defrost Operation

Defrost occurs after predetermined length of compressor run hours. Compressor run time between defrosts changes, or adapts, depending upon recent history of defrost lengths (time it takes for defrost terminator to open after defrost heater has been turned on).

• Defrost terminator opens at 48°F and closes at 15°F.

• Compressor run time between defrosts (CRTD) will be one of 3 values under normal operation: CRTD 1 (8 hours) or CRTD 2 (12 hours) or CRTD 3 (16 hours).

If defrost length is low (DT-LO defined as 21 minutes) indicating small frost load, CRTD for next defrost cycle is advanced to next level.

If defrost length is high (DI - HI defined as 24 minutes) indicating large frost load, CRTD for next defrost cycle is lowered to next level.

If defrost length is between 21 and 24 minutes, CRTD for next defrost cycle remains the same.

Initial value at power up CRTD 0 is 4 hours.

• Vacation Mode CRTD equals 96 hours. Vacation Mode CRTD is interrupted with door openings. Defrost interval will revert back to interval before Vacation Mode. Three things must occur to reach Vacation Mode CRTD:

1) Defrost interval must be CRTD 3 (16 hours).

2) Both refrigerator and freezer doors must have

remained closed since last defrost cycle.

3) Defrost thermostat must have opened in less

than 21 minutes during last defrost cycle.

• Six minute dwell time occurs after defrost terminator opens before compressor and condenser fan motor will operate. Ten minute dwell time occurs after defrost terminator opens before evaporator fan motor will operate. Dwell time can be bypassed by disconnecting power to the unit for 30 seconds.

• Conventional defrost can be selected in Program Mode B.
