IMPORTANT: Be sure the power switch is set to the On position
after cleaning refrigerator or changing light bulbs.

Read all directions before you begin.
IMPORTANT:
When your refrigerator was installed, the water connection
from the water source should have been connected to your
refrigerator. If your refrigerator is not connected to a water
source, see "Connect to Water Line" in the Installation
Instructions. If you have any questions about your water
connection, see "Troubleshooting" or call a licensed, qualified
plumber.
If you turn the refrigerator on before the water line is
connected, turn the ice maker OFF. See "Ice Maker and
Storage Bin."
All installations must meet local plumbing code requirements.
Water Pressure
A cold water supply with water pressure between 30 and 120 psi
(207 and 827 kPa) is required to operate the water dispenser and
ice maker. If you have questions about your water pressure, see
"Troubleshooting" or call a licensed, qualified plumber.
Reverse Osmosis Water Supply
IMPORTANT: The pressure of the water supply coming out of a
reverse osmosis system going to the water inlet valve of the
refrigerator needs to be between 30 and 120 psi (207 and
827 kPa).
If a reverse osmosis water filtration system is connected to your
cold water supply, the water pressure to the reverse osmosis
system needs to be a minimum of 40 psi (276 kPa).
If the water pressure to the reverse osmosis system is less than
40 psi (276 kPa):
Check to see whether the sediment filter in the reverse
osmosis system is blocked. Replace the filter if necessary.
Allow the storage tank on the reverse osmosis system to refill
after heavy usage.
If your refrigerator has a water filter, it may further reduce the
water pressure when used in conjunction with a reverse
osmosis system. Remove the water filter. See "Water
Filtration System."
If you have questions about your water pressure, call a licensed,
qualified plumber.
No r ma l So u n ds
Your new refrigerator may make sounds that your old one didn't
make. Because the sounds are new to you, you might be
concerned about them. Most of the new sounds are normal. Hard
A
surfaces, such as the floor, walls, and cabinets, can make the
sounds seem louder. The following describes the kinds of sounds
and what may be making them.
If your refrigerator is equipped with an ice maker, you will hear
a buzzing sound when the water valve opens to fill the ice
maker for each cycle.
Your refrigerator is designed to run more efficiently to keep
your food items at the desired temperatures and to minimize
energy usage. The high efficiency compressor and fans may
cause your refrigerator to run longer than your old one. You
may also hear a pulsating or high-pitched sound from the
compressor or fans adjusting to optimize performance.
You may hear the evaporator fan motor circulating air through
the refrigerator and freezer compartments. The fan speed
may increase as you open the doors or add warm food.
Rattling noises may come from the flow of refrigerant, the
water line, or items stored on top of the refrigerator.
Water dripping on the defrost heater during a defrost cycle
may cause a sizzling sound.
As each cycle ends, you may hear a gurgling sound due to
the refrigerant flowing in your refrigerator.
Contraction and expansion of the inside walls may cause a
popping noise.
You may hear air being forced over the condenser by the
condenser fan.
You may hear water running into the drain pan during the
defrost cycle.

In order to ensure proper temperatures, you need to permit
airflow between the refrigerator and freezer sections. As shown in
the illustration, cool air enters the freezer section through vents in
the rear and top. The air flows forward through the freezer section
and recirculates under the freezer floor. Cool air enters the
refrigerator section through the top, flows down and across
shelves to the doors and recirculates to return air vents at the
bottom.
Do not block any airflow vents. If the vents are blocked, airflow
will be obstructed and temperature and moisture problems may
occur.
