Step-by-step installation

STEP 1 Select a site

The site must:

• Have a solid level surface without carpeting or flooring that may obstruct ventilation
• Be out of direct sunlight
• Have adequate room for opening and closing the door
• Be away from any heat source
• Provide room for maintenance and servicing
• Have a temperature range between 50 °F (10 °C) and 110 °F (43 °C)

Clearance

See the pictures and table below and on the next page for installation space requirements.

NOTE

The measurements of your refrigerator may differ from those listed above, depending on the measuring method.

STEP 2 Flooring

• The surface of the installation location must support a fully loaded refrigerator.
• To protect the floor, put a large piece of cardboard under each leg of the refrigerator when you move it for installation.
• To protect the floor once the refrigerator is in its final position, do not move it unless necessary. If you have to move it, place thick paper or cloth such as an old carpet, along the movement path.

STEP 3 Adjust the levelling feet

- To narrow the gap, turn the gap bolt counterclockwise.

3. When done, reinsert the top cover, and then reinsert the screws that hold it in place. Tighten the screws.

STEP 5 Connect the water dispenser line

A water dispenser with a filter is one of the helpful features on your new refrigerator. To help promote better health, the water filter removes unwanted particles from your water. However, it does not sterilize or destroy microorganisms. You may need to purchase a water purifying system to do that.

The water line also connects to the ice maker. For the ice maker to operate properly, a water pressure of 20-125 psi is required.

If the refrigerator is installed in an area with low water pressure (below 20 psi), you can install a booster pump to compensate for the low pressure.

After you have connected the water line, make sure the water storage tank inside the refrigerator is properly filled. To do this, press the water dispenser lever until the water runs from the water outlet.

WARNING

• Keep ventilation openings, in the appliance enclosure or in the built-in structure, clear of obstruction. Connect to potable water supply only.

1. Shut off the main water source.
2. Insert the pipe clamp (B) and the shut off valve (C) into the cold water line (A).
3. Connect the water line installation kit (A) to the shut off valve (B)

Connect the water supply line to the refrigerator

Ice maker

The refrigerator has a built-in ice maker that automatically dispenses ice so that you can enjoy filtered water with cubed or crushed ice.

Ice making

After you have installed your refrigerator and plugged it in, follow these instructions to ensure proper ice making and to keep the ice bucket full of ice:

1. Let the refrigerator run at least 24 hours without dispensing ice for optimal performance.
2. Dispense the first 4 to 6 ice cubes into a glass.
3. Wait another 8 hours and dispense another 4 to 6 ice cubes.
4. Then, wait another 16 hours and dispense the first glass-full of ice.

Diagnosis

If ice does not dispense, first check the ice maker. To check the ice maker

1. Press Test on the side of the ice maker. You will hear a chime (ding-dong) when you press the button.
2. You will hear another chime if the ice maker is operating properly.

Ice Maker Off

To disable the icemaker, tap Fridge Manager > Fridge Settings > Ice Maker on the Home screen, and then select Off. Make sure to empty the ice bucket. Remaining ice cubes may clump together, making it difficult to remove them.

To remove the ice bucket

1. Hold the bottom of the ice bucket with one hand and hold the side with the other hand.
2. Gently lift it up and pull out.
3. Remove the remaining ice cubes, and then put the ice bucket back into place.

If the bucket does not fit in, turn the helix screw 90 degrees, and then try again.

Water clouding

• Water supplied to the refrigerator flows through a core alkaline filter. During this filtering process, the water pressure of the water increases and the water becomes saturated with oxygen and nitrogen. This causes the water to look misty or cloudy temporarily when dispensed. This is normal and the water will look clear after a few seconds.

Wine Rack

The refrigerator ships with a wine rack, which can be positioned in one of 3 positions: under the shelf, in the partition guide, or on top of the sliding shelf of the FlexZone. The position or positions available to you depends on your model.

CAUTION

When you remove or insert the wine rack, make sure that the wine rack is empty.

Under the shelf

Insert the wine rack under the shelf of the fridge. Make sure to insert it all the way to the end as shown in the figure.

In the partition guide

Insert the wine rack in the partition guide of the FlexZone.

• Make sure the front of the wine rack fits in the partition guide on the inner left-hand side of the FlexZone.

• Set the temperature of the FlexZone to White Wine.

On the sliding shelf

Do you hear abnormal sounds from the refrigerator?

Before calling for service, review the information below. If you still have questions about sounds your refrigerator is making, please call Samsung Customer Care at 1-800-SAMSUNG (726-7864). Note that you will be charged for any service visits related to normal operating sounds in which no defects were found.

These sounds are normal.

• When starting or ending an operation, the refrigerator may make sounds similar to a car engine ignition. As the operation stabilizes, the sounds will decrease.

• While the fan is operating, these sounds may occur. When the refrigerator reaches the set temperature, the fan sound will stop.

• During a defrost cycle, water may drip on the defrost heater, causing sizzling sounds.

• As the refrigerator cools or freezes, refrigerant gas moves through sealed pipes, causing bubbling sounds.

• As the refrigerator temperature increases or decreases, plastic parts contract and expand, creating knocking noises. These noises occur during the defrosting cycle or when electronic parts are working.

• For ice maker models: When the water valve opens to fill the ice maker, you may hear a buzzing sound.

• Due to pressure equalizing when you open and close the refrigerator door, you may hear a whooshing sound.
