USER MANUAL OF FRENCH DOOR REFRIGERATOR





Before Beginning
This water line installation is not covered by the refrigerator warranty. Follow these instructions carefully to minimize the risk of expensive water damage.
If necessary, call a qualified plumber to correct water hammer before installing the water supply line to the refrigerator. Water banging in the pipes, or water hammer in residential plumbing can cause damage to refrigerator parts and lead to water leakage or flooding.
WARNING Connect to potable water supply only.
CAUTION
If the water pressure from the reverse osmosis system is less than 20 psi or 138 kPa or 1.4 kgf/ cm2 takes more than 4 seconds to fill a cup of 7 oz or cc capacity):
Supplies Needed
Be sure there is sufficient extra tubing (about 8 feet m] coiled into 3 turns of about 10 in. [25 cm] diameter) to allow the refrigerator to move out from the wall after installation.
The shutoff valve should have a water inlet with a minimum inside diameter of 5/32 in. at the point of connection to the COLD WATER LINE. Saddle-type shutoff valves are included in many water supply kits. Before purchasing, make sure a saddle-type valve complies with your local plumbing codes.
Water Line Installation Instructions
WARNING Electric Shock Hazard:
Install the shutoff valve on the nearest frequently used drinking water line.
1. Shut off the main water supply.
Turn on the nearest faucet to relieve the pressure on the line.
2. Choose the valve location.
Choose a location for the valve that is easily accessible. It is best to connect into the side of a vertical water pipe. When it is necessary to connect into a horizontal water pipe, make the connection to the top or side, rather than at the bottom, to avoid drawing off any sediment from the water pipe.

3. Drill the hole for the valve.
Drill a 1⁄4 in. hole in the water pipe using a sharp bit. Remove any burrs resulting from drilling the hole in the pipe. Be careful not to allow water to drain into the drill. Failure to drill a 1⁄4 in. hole may result in reduced ice production or smaller cubes.

NOTE
The hookup line cannot be white, plastic tubing. Licensed plumbers must use only copper tubing NDA tubing #49595 or #49599) or Cross Link Polyethylene (PEX) tubing.
4. Fasten the shutoff valve.
Fasten the shutoff valve to the cold water pipe with the pipe clamp.

NOTE
5. Tighten the pipe clamp.
Tighten the clamp screws until the sealing washer begins to swell.

NOTE
Do not over tighten clamp or you may crush the tubing.
6. Route the tubing.
Route the tubing between the cold water line and the refrigerator.
Route the tubing through a hole drilled in the wall or floor (behind the refrigerator or adjacent base cabinet) as close to the wall as possible.
NOTE
7. Connect the tubing to the valve.
Place the compression nut and ferrule (sleeve) for copper tubing onto the end of the tubing and connect it to the shutoff valve.
Make sure the tubing is fully inserted into the valve. Tighten the compression nut securely.

8. Flush out the tubing.
Turn the main water supply on and flush out the tubing until the water is clear. Shut the water off at the water valve after about one quart of water has been flushed through the tubing.

9. Connect the tubing to the refrigerator.
NOTE

10. Turn the water on at the shutoff valve.
Tighten any connections that leak.

WARNING Personal Injury Hazard
CAUTION
Never store beverage cans or other items in the ice bin for the purpose of rapid cooling. Doing so may damage the icemaker or the containers may burst.
NOTE
Wrap or store food in the refrigerator in airtight and moisture-proof material unless otherwise noted. This prevents food odor and taste transfer throughout the refrigerator. For dated products, check date code to ensure freshness.

Check a freezer guide or a reliable cookbook for further information about preparing food for freezing or food storage times.
Freezing
Your freezer will not quick-freeze a large quantity of food. Do not put more unfrozen food into the freezer than will freeze within 24 hours (no more than 2 to pounds of food per cubic foot of freezer space).
Leave enough space in the freezer for air to circulate around packages. Be careful to leave enough room at the front so the door can close tightly.
Storage times will vary according to the quality and type of food, the type of packaging or wrap used how airtight and moisture-proof) and the storage temperature. Ice crystals inside a sealed package are normal. This simply means that moisture in the food and air inside the package have condensed, creating ice crystals.
NOTE
Packaging
Successful freezing depends on correct packaging.
When you close and seal the package, it must not allow air or moisture in or out. If it does, you could have food odor and taste transfer throughout the refrigerator and could also dry out frozen food.

Smart Saving_Demand Response
You can lower energy usage based on Demand
Response (DR) signals from the utility company. If the refrigerator is operating in Smart Saving mode according to the DR signal, you can see a pop up.
Seasonal Energy Savings
Lower energy usage based on time period.
Using the Smart Grid Function
This feature responds to notification events from your utility company to run high energy consuming tasks during off-peak periods when demand is lower. These notification events are known as Demand Response signals.
If the refrigerator receives a Demand Response signal from the utility company, the refrigerator will turn on the Grid LED on the refrigerator display and control its power consumption according to the signal.
The refrigerator will respond to the signals received from the utility company as long as product performance is maintained.
If the refrigerator receives a Demand Response signal, the refrigerator will operate in Delay Appliance Load (DAL) or Temporary Appliance Load Reduction TALR) mode.
Delay Appliance Load (DAL)
The refrigerator responds to a DAL signal by providing a moderate load reduction for the duration of the delay period.
This mode controls functions that consume a lot of energy such as adjusting the cooling system, running the defrost cycle, and making ice.
Temporary Appliance Load Reduction (TALR)
The refrigerator responds to a TALR signal by aggressively reducing the load for a short time period, typically 10 minutes. This mode reduces energy consumption by stopping the compressor and controlling the functions that consume a lot of energy such as the defrost cycle and fan.
Override Smart Grid Mode
To ignore the Demand Response signal from the utility company and override the Smart Grid function, push the Smart Grid button while the refrigerator is in Smart Grid mode.
When you override the Smart Grid function, the refrigerator ignores the Demand Response signal and is no longer controlled by the utility company until the next Demand Response signal is sent. You can also override the Smart Grid function using the smart phone app.

=> During the defrost cycle, the temperature of each compartment may rise slightly. Wait 30 minutes and confirm the proper temperature has been restored once the defrost cycle has completed.
=> It may take up to 24 hours for each compartment to reach the desired temperature.
=> If the refrigerator was stored for a long period of time or moved on its side, it is necessary for the refrigerator to stand upright for 24 hours before connecting it to power.
Cooling system runs too much.
=> Modern refrigerators require more operating time but use less energy due to more efficient technology.
=>The refrigerator will take up to 24 hours to cool completely.
=> Adding food and opening the door warms the refrigerator, requiring the compressor to run longer in order to cool the refrigerator back down. In order to conserve energy, try to get everything you need out of the refrigerator at once, keep food organized so it is easy to find, and close the door as soon as the food is removed. (Refer to the Food Storage Guide.)
=> Firmly push the doors shut. If they will not shut all the way, the "Doors will not close correctly or pop open" section.
=> The compressor will run longer under warm conditions. At normal room temperatures (70 °F) expect your compressor to run about 40 % to 80 % of the time. Under warmer conditions, expect it to run even more often. The refrigerator should not be operated above
=>Use a vacuum cleaner with an attachment to clean the condenser cover and vents. Do not remove the panel covering the condenser coil area.
Interior moisture buildup.
=> When the doors are opened often or for long periods of time, warm, humid air enters the compartment.This raises the temperature and moisture level within the compartment. To lessen the effect, reduce the frequency and duration of door openings.
=> Humid weather allows additional moisture to enter the compartments when the doors are opened leading to condensation or frost. Maintaining a reasonable level of humidity in the home will help to control the amount of moisture that can enter the compartments.
=> During the defrost cycle, the temperature of each compartment may rise slightly and condensation may form on the back wall. Wait 30 minutes and confirm that the proper temperature has been restored once the defrost cycle has completed.
=> Food stored uncovered or unwrapped, and damp containers can lead to moisture accumulation within each compartment. Wipe all containers dry and store food in sealed packaging to prevent condensation and frost.
Food is freezing in the refrigerator compartment.
=> Rearrange items with high water content away from air vents.
=> If the temperature is too cold, adjust the control one increment at a time and wait for the temperature to stabilize. Refer to the Control Panel section for more information.
=> When the refrigerator is operated in temperature below 41°F (5°C), food can freeze in the refrigerator compartment. The refrigerator should not be operated in temperature below 55°F (13°C).
The refrigerator or Freezer section is too warm.
=> It may take up to 24 hours for each compartment to reach the desired temperature.
=> Locate air vents by using your hand to sense airflow and move all packages that block vents and restrict airflow. Rearrange items to allow air to flow throughout the compartment.
=>When the doors are opened often or for long periods of time, warm, humid air enters the compartment.This raises the temperature and moisture level within the compartment. To lessen the effect, reduce the frequency and duration of door openings.
=> The refrigerator should not be operated in temperatures above 110 °F.
=> Adding food warms the compartment requiring the cooling system to run. Allowing hot food to cool to room temperature before putting it in the refrigerator will reduce this effect.
=> If the temperature is too warm, adjust the control one increment at a time and wait for the temperature to stabilize.
=> During the defrost cycle, the temperature of each compartment may rise slightly and condensation may form on the back wall. Wait 30 minutes and confirm the proper temperature has been restored once the defrost cycle has completed.

=> This is normal for food items with a high water content.
=> Do not store food items with high water content in the freezer for a long period of time.
Frost or ice crystals form on frozen food (outside of package).
=> When the doors are opened often or for long periods of time, warm, humid air enters the compartment. This raises the temperature and moisture level within the compartment. Increased moisture will lead to frost and condensation. To lessen the effect, reduce the frequency and duration of door openings.
Icemaker is not making enough ice.
=> The icemaker will produce approximately 70-184 cubes in a 24 hour period.
=> Connect the refrigerator to a cold water supply with adequate pressure and turn the water shutoff valve fully open. If the problem persists, it may be necessary to contact a plumber.
=>Replacing the water filter is recommended:
=>Approximately every six months.
=>When the water filter indicator turns on.
=>When the water dispenser output decreases.
=>When the ice cubes are smaller than normal.
=>The water pressure must be between 20 and 120 psi on models without a water filter and between 40 and psi on models with a water filter. If the problem persists, it may be necessary to contact a plumber.
=>Reverse osmosis filtration systems can reduce the water pressure below the minimum amount and result in icemaker issues. (Refer to the Connecting the Water Line section.)
=>The tubing can kink when the refrigerator is moved during installation or cleaning resulting in reduced water flow. Straighten or repair the water supply line and arrange it to prevent future kinks.
=>If the doors of the unit are opened often, ambient air will warm the refrigerator which will prevent the unit from maintaining the set temperature. Lowering the refrigerator temperature can help, as well as not opening the doors as frequently.
=>If the doors are not properly closed, ice production will be affected. See the "Doors will not close correctly or pop open" section in Parts & Features Troubleshooting for more information.
=>The recommended temperature for the freezer compartment for normal ice production is 0°F. If the freezer temperature is warmer, ice production will be affected.
Icemaker is not making ice
=>It may take up to 24 hours for each compartment to reach the desired temperature and for the icemaker to begin making ice.
=>Locate the icemaker ON/OFF and confirm that it is turned on.
=>Foreign substances or frost on the ice-detecting sensor can interrupt ice production. Make sure that the sensor area is clean at all times for proper operation.
=>Connect the refrigerator to the water supply and turn the water shutoff valve fully open.
=>If your icemaker is equipped with an ice shutoff arm, make sure that the arm moves freely. If your icemaker is equipped with the electronic ice shutoff sensor, make sure that there is a clear path between the two sensors.
=>Reverse osmosis filtration systems can reduce the water pressure below the minimum amount and result in icemaker issues. (Refer to the Connecting the Water Line section.)
Ice has bad taste or odor.
=>A water filter may need to be installed to eliminate taste and odor problems. NOTE: In some cases, a filter may not help. It may not be possible to remove all minerals/ odor/taste in all water supplies.
=>Ice that has been stored for too long will shrink, become cloudy, and may develop a stale taste. Throw away old ice and make a new supply.
=>Rewrap the food. Odors may migrate to the ice if food is not wrapped properly.
=>Empty and wash the bin (discard old cubes). Make sure that the bin is completely dry before reinstalling it.
Icemaker is making too much ice.
=>Empty the ice bin. If your icemaker is equipped with an ice shutoff arm, make sure that the arm moves freely. If your icemaker is equipped with the electronic ice shutoff sensor, make sure that there is a clear path between the two sensors. Reinstall the ice bin and wait hours to confirm proper operation.
