Introduction

2001 SxS Energy models are being introduced in response to the requirements of more energy-efficient refrigerators by mid2001, along with improvements in features and operation. The primary differences in this cooling system are the defrosting

adaptable system (watch Pub # 31-9062), control board,

software, and systems control that operate regardless in the sections of the cooler and freezer. The new high-efficiency control system has the ability of cycling components and adjusting the fan speeds as required, to maintain the temperature adjustment ranges in the cooler and freezer sections. The feedback systems are digital inputs and relay outputs. The sensors (thermistors) are used to measure the temperature with communication to the main board, which controls the components of the unity.

The refrigerator has key controls to give inputs to the microprocessor. The cooler and freezer controls are of the temperature control point type and have settings of 0-9 with 9 being the coldest possible temperature. The new NONCLEAN condenser is repairable from the back and is designed to prevent the customer from having to clean the condenser in conditional normal use.

The sealed operation system and the compressor are working in the same way as the previous models, with some minor changes.

The collateral models Profile Performance and Arctica are the affected models. These models are available with cold water through the door and ice dispenser, and a water filter detail that can be filled. In models that require an ice machine, the new electronic ice machine model (see Pub. #

31.09063) has been or can be installed.

The freezer has built-in grills, a spill-proof grill that pulls out, an Easy Space grill, deep door grills, based on the model. The chiller section has a Baking Soda holder, a fruit and vegetable drawer, drawer dividers, and a moisture-adjustable drawer and a convertible meat drawer.

The new high-efficiency refrigerator is a combination of the most efficient refrigeration systems and the most desirable customer details available.

IMPORTANT: PLEASE READ CAREFULLY

FOR PERSONAL SAFETY, THIS APPLIANCE MUST BE ADEQUATELY GROUNDED

The power cord of this appliance is equipped with a three-prong (grounded) connector that fits a three-pronged (grounded) standard receiver to minimize the risk of an electrical hazard to this appliance. The customer should check the wall receiver and the circuit by a qualified electrician to make sure that the appliance is properly grounded.

Where a standard two-pronged wall receiver is located, it is the customer's responsibility and personal obligation to exchange it for a properly grounded three-prong wall receptacle. NDER NO CIRCUMSTANCES, CUT OR REMOVE THE THIRD POINT OF THE (EARTH) CONNECTOR FROM THE ENERGY CORD. SITUATIONS OF USE IN WHICH THE ELECTRICAL CORD OF THE APPLIANCE WILL BE DISCONNECTED INFRECTIVELY Due to potential safety hazards under certain conditions, we strongly recommend against the use of an adapter plug. Without em However, if you always choose to use an adapter where local codes permit, a TEMPORARY CONNECTION can be made to a properly grounded two-prong wall receptacle approved by the UL adapter list which is available in most of the hardware stores. The largest hole in the adapter must be aligned to give an appropriate polarity in the power cord connection. to CAUTION: Connecting the terminal of the grounding adapter to the screw cover of the wall receiver does not ground the device, unless the cover of the screw is made of metal, and is not insulated and the receiver of the wall is grounded through the wiring of the house. The customer must check the circuit by a qualified electrician to make sure the receiver is properly grounded. When disconnecting the power cord from the adapter, always hold the adapter with one hand. If you do not do this, the terminal of the ground adapter is very safe to break with repeated use. If this happens, DO NOT use the appliance until a ground connection has beenestablished

SITUATIONS OF USE IN WHICH THE ELECTRICAL CORD OF THE APPLIANCE WILL BE DISCONNECTED FREQUENTLY Do not use an adapter plug in these situations because frequently disconnecting the power cord places undue stress on the adapter and leads to eventual failure of the adapter terminal to ground. The customer must change the two-pronged receiver on the wall for a receiver Three-prong (grounded) by a qualified electrician before using the appliance.

Independent Operation of the Refrigerator / Freezer

In previous models, the chiller and freezer compartment components worked at the same time. When the cooler compartment asked for cold air, the components of the freezer compartment worked with the components of the cooler compartment. This is called operation no Independent.

In this model, the components of the compartment of the cooler they can operate without the operation of the components of the freezer compartment. This is called independent operation.

Normal Operating Characteristics that may Occur, but Different from Previous Models

• The ice machine's drill rotates in the direction of the

hands of the clock.

• The evaporator fan operates without the compressor or

condenser fan. Refrigerator fan is switched on.

• Post Rest (adaptive defrost), compressor fan and condenser

on with the evaporator fan off after the defrost cycle.

• Lining Protection Mode, fans come on when doors open

for 3 minutes.

• When the doors open, the fans turn off.

• There is no air flow to the cooler compartment when the

evaporator fan is on.

• The evaporator and compressor fan can operate

continuously for 8 hours.

• The fans change speeds, different levels of sound can be

noticed when this happens.

• Quick Ice Mode, the evaporator fan works for 48 hours

without stopping.

• Response time for drastic temperature changes is 2 to 10

minutes. The main control board will only respond to 8 degrees of temperature change per minute as determined by the change of resistance of thesensor.

- 7 -

Abnormal Operation Characteristics (Incorrect Operation)

• Cooler fan on and evaporator fan off.

• Evaporator fan on, cooler fan and compressor off,

and damper closed.

• Quick changes in fan speed, the fan takes at least 1

minute to change speeds.

• The compressor running without the condenser

fan. The compressor and condenser fan forever must of functional to the same weather.

• The condenser fan running without the

compressor. The compressor and condenser fan should always work at the same time.

Adaptive Defrosting

Adaptive defrosting can be described as a defrosting system that adapts to the environment around the refrigerator and the use of the home.

Unlike traditional defrosting systems that use electromechanical timers with a Fixed defrost cycle time, adaptive defrost uses intelligent electronic control to determine when the defrosting cycle is necessary. In order to achieve the correct defrosting time cycle, the main control board monitors the following cooler operations:

• Length of time when the refrigerator doors were

opened since the last defrost cycle.

• Length of time that the compressor has operated

since the last defrost cycle.

• Amount of time that the defrost heaters were on since

the last cycle of defrosting.

• Adaptive defrosting is divided into separate

cycles. These operations are:

• Cooling operation Pre-cooling

operation

• Defrosting Heater Operation Rest Period

• Post Break

See Pub # 31-9062 for more information on Defrosting Adaptable

Cooling Operation (Defrosting Adaptable)

During the cooling operation, the main control board monitors door openings (cooler and freezer doors) and

operating time of the compressor. The length of time between consecutive defrosts is reduced by each open

door. If the doors are not opened, the compressor will

work up to 60 hours between defrosting. If the doors open

frequently and / or for long periods, the operating time of the compressor between defrosting will be reduced to as

little as 8 hours

Pre-Cooling Operation (Defrosting Adaptable)

When the main control board determines that the defrosting is necessary, the main control board will force

the refrigerator to a continuous mode cooling (precooling). During pre-cooling, the freezer temperature can

be carried down the set point temperature of the control panel screen. However, the temperature of the cooler will

be regulated by the shock absorber Pre-cooling and will

last 2 hours if it is not interrupted by some open door. If after 8 hours, the unit could not complete a pre-cooling without interrupting, the defrost cycle will continue.

Operation of the defrost heater

After 2 hours of pre-cooling operation or 8 hours of

interrupted pre-cooling attempts, the main control board turns

off the compressor, condenser fan and the evaporator fan. The main control board then energizes the defrost relay,

which completes the Defrost Cycle.

A thermostat-defrosting (switch) protects the defrosting system. The thermostat opens when the evaporator temperature rises to 140 ° Fahrenheit and closes when the evaporator temperature drops to 110 degrees Fahrenheit.

Rest Period (Adaptive Defrosting)

After the main control board has completed the operation of the defrosting heater, there is a resting period of 5 minutes. During this period, the compressor, condenser fan and evaporator fan they stay off. Frost melting that remains of the evaporator will continue to fall and drain to that the evaporator to be completely clean of any humidity before the cooling operation. After 5 minutes of resting period, the unit enters a post break.

Post Rest (Adaptive Defrosting)

The post-rest period is designed to cool the evaporator before circulating the air inside the refrigerator. This prevents any residual heat in the evaporator from being distributed in the freezer. During this period, the compressor and the condenser fan are on, but all the interior fans are off and the shock absorber is turned off. Post-rest times vary with the different Models. However, there is a maximum of 5-minutes of resting time.

Liner Protection Mode

The liner protection mode will be activated if any of the doors have been opened for 3 minutes. This mode will start the fans and will close the damper. This mode is controlled by 2 timers. Timer # 1 monitors door open time. A 3-minute open count. The door will start when the door is opened. If it passes 3 minutes before the door is closed, the protection mode of lining will be activated. Once the door is closed, timer # 1 is reset and the liner protection mode passes to reserve. In reserve, normal fan and damper operations begin and timer # 2 begins a count of 3 closed door minutes. If you spend 3 minutes without opening the door, the liner protection mode will be completely deactivated. If a door is opened within the timer #2 coun 2 closed door, the remaining time in door counting closed the count of timer # 1 of open door will be deducted.

During the defrosting operation, the main control board monitors the evaporator temperature using inputs to the evaporator thermistor. The thermistor will usually end the operation of the thermistor heater in less than 20 minutes. The typical thawing time is 20-30 minutes.

Dispenser functions

The main control board controls the functions of

water, crushed ice and cubed ice. To select a

function, press the appropriate key on the

dispenser. The led will light to identify the selection.

To dispense the chosen option, press the dispenser

holder located at the entrance of the dispenser. The set of selenoid and link will open the ice firing gate

to dispense the ice. If cube ice is selected, the solenoid deviation of crushed ice will allow cube ice

to be deviate from the ice crusher. The ice trigger door must stay open for 5 seconds after it has

stopped the dispensation. After a delay of 5 seconds, the set of selenoid and link will close the ice trigger door. The dispenser light will turn on automatically when

the dispenser holder is depressed and will gradually

disappear 5 seconds after it was released. The

dispenser selection is recorded on the main control

board. In the case of a power failure, the last selected function will be restored.

Fast Ice

The quick ice detail is available on some models.

This detail causes the evaporator fan to operate without stopping for 48 hours (the fan can operate at

high or low speed). This allows a maximum output of the ice machine.

The QUICK ICE key starts the quick ice mode in the

refrigerator. By pressing the QUICK ICE key the LED is unlimited and adjusts the evaporator fan

operating at medium speed (unless the main control board selects high speed) for a period of 48

hours. The evaporator fan is finished during thawing, rest, post rest and doors opening.

The selection of quick ice is stored in the principal

control panel. The function will be restored in the case of lack of energy.

Door alarm

The DOOR ALARM key is used to turn on and off the alarm detail of the door. If the detail is on, the DOOR ALARM LED will flash when the door is opened. If the door opens for more than 2 minutes, the door alarm will sound. The alarm can be stopped by pressing the DOOR ALARM key or closing the door. If the DOOR ALARM key is pushed while the door is open, the alarm will stop but the led will continue to flash until the door is closed. When the door is closed, the audible alarm will be restored. This detail will be retained in the event of a power failure

Dispenser Light

The LIGHT key turns the dispenser light on and off. When the light is off, it will gradually disappear. The dispenser light will turn on automatically when the dispenser holder is depressed and will disappear gradually 5 seconds after it was released. The LIGHT key will not turn off the light while dispensing.

Closing the Dispenser

When the dispenser system is closed, no dispensing commands will be accepted. This includes dispenser support and will prevent accidental waivers that may be caused by children or pets. If you press a key with the system closed, it will be recognized with three presses of the LOCK LED accompanied by an audible tone.

To close or open communication between the dispenser and the main control board, press the LOCK key and hold it for 3 seconds. The LOCK LED will flash while the LOCK key is pressed. When the communication is closed, the LOCK LED will light up.

The status of other functions, selected before the start of the closing detail, will be displayed on the screen. If the latch is engaged while a mode is activated, the LED will stay on until the mode ends.

If the latch is engaged when the filtering time ends, the LED will light but cannot be reset until the latch is turned off.

The closing detail will be retained during a power cut.

Filters

The FreshSaver filter is located in the fresh food drawer and will last for 1 year. Some models are equipped with a FreshSaver FILTER LED. After a 1-year refrigerator operation time the FreshSaver filter LED will illuminate as a reminder for the owner to change the filter. The LED can be readjusted by pressing and holding the HOLD 3 SECS key for 3 seconds. The LED will flash while the key is pressed, it will remain illuminated for 3 seconds after the key has been released and turned off.

Some models are equipped with a water filter that is located in the upper corner of the right side of the cooler compartment. The filters are designed to be used for up to 18 hours of valve open time or 1 year of clock time.

When 90% of the filter time has passed (valve open time or clock time, whichever comes first) the main control board will illuminate the filter reminder LED (amber). When 100% of the filter time has passed, the main control board will illuminate the filter reminder LED (Red).

Hinge and Door Closing System

The hinge clamps are not adjustable in the cabinet. The cooler door can be adjusted up and down using the hinge adjustment pin (located on the bottom hinge of the cooler door).

This refrigerator is equipped with an open / close door detail. This detail consists of a loaded spring arm located in the lower part of the cabinet for each door. The arm stops the door when it is partially open and automatically closes the door when it is almost closed

IMPORTANT:

The refrigerator rollers must be properly adjusted for proper door closure. When the wheels are adjusted correctly, the door should close easily when it opens approximately 45 degrees (half way).

Air Flow (Cabinet Interior)

AIR FLOW

The freezer cabinet is designed so that air is carried inside the lower part of the air tunnel and through the evaporator when the evaporator fan is operating. The cold air is then pushed out towards the top of the freezer.

The cooler compartment receives cool air through an electronic shock absorber that is located in the upper rear of the cooler between the freezer cabinet and the cooler cabinet. The cushion is controlled by the main control board and when it is opened, it allows the cold air from the freezer air tunnel to move inside the cooler's air tower. The cold air tower of the cooler contains a cooling fan that draws cold air from the freezer (through the damper) into the air tower. The air tower directs cool air through the top of the cooler cabinet to two exits. The air tower also directs cool air down the back of the wall of the cooler cabinet. The cold air draws the air out of the tower through fans in the tower.

The air returns from the cooler cabinet to the freezer cabinet through an upright located on the left side of the fresh food drawer.

HERRAMIENTA LOKRING

CONECTOR

Bronce

PROTECTOR DE CALOR

SOLDADOR

There are two approved methods to change the evaporator. The Lokring method does not require welding, since it uses tight mechanical connections. The heat shield uses the traditional soldering method, but gives protection to the upper liner while welding the evaporator connections in the freezer compartment.

Always add a new drying filter when repairing the sealed system. Follow each step of the instructions included with the evaporator replacement.

LOKRING METHOD

Lokring is a method to install the evaporator in the freezer without using a torch. It uses a mechanical connection instead of a soldered connection. Apply a few drops of LokPrep (a special cleaning solution and seal) to the terminals of the pipe you wish to join. The Lokring tool compresses the connector to ensure a tight mechanical connection. The parts shown on the right are required to use the Lokring replacement method.

For additional information on how to use the Lokring, call 1-800-848-7722 & order publication # 31-9067 (Lokring Repair Procedures Manual) and Publication # 31-9066 (VHS Video Cassette Lokring Repair Procedures)

HEAT PROTECTOR METHOD

The heat protection kit is used to prevent damage to the refrigerator liner when soldering the evaporator in the sealed system. See the instructions included in the heat protection kit. The kit comes with enough heat absorbing paste, soldering iron and adhesive to finish four repairs.
