Please observe the following safety precautions to use the
refrigerator safely and correctly and to prevent accident or
injury when servicing.
1. Be careful of an electric shock. Disconnect power cord
from wall outlet and wait for more than three minutes
before replacing PWB parts. Disconnect the power
whenever replacing and repairing electric components.
2. If disconnecting the power, wait at least 5 minutes
before plugging the unit back in.
3. Before touching the power cord, make sure the cord is
not damaged. If the power cord is damaged, it can
cause a fire or an electrical shock.
4. Make sure the unit has a dedicated circuit breaker.
Overloading the circuit can cause a fire.
5. Please make sure the outlet is properly grounded.
Particularly in a wet or damp area.
6. Use standard electrical components.
7. Remove dust and foreign materials from the housing
and connecting parts.
8. Do not fray, damage, run over, kink, bend, pull out, or
twist the power cord.
9. Please check for evidence of moisture intrusion in the
electrical components. Replace the parts or mask with
insulation tape if moisture intrusion is confirmed.
10. Stay clear of the icemaker with hands or tools if the unit
has power. Do not try to manually turn the ice maker
even when turned off.
11. Customers should not repair the refrigerator
themselves. This work requires special tools and
knowledge. Non-professionals could cause fire, injury,
or damage to the product.
12. Do not store flammable materials such as ether,
benzene, alcohol, chemicals, or gas in the refrigerator.
13. Do not put anything on top of the refrigerator,
especially something containing water, like a vase.
14. Do not put glass bottles of water into the freezer. The
contents will freeze and break the bottles.
15. If you scrap or discard the refrigerator, remove the
doors and dispose of it where children are not likely to
play in or around it.

Filter
Replace the filter when the indicator light comes on or the
performance of the icemaker or water dispenser decreases
noticeably.
After changing the water filter cartridge, reset the water
filter status display and indicator light by pressing and
holding the BUTTON for 3 seconds.(page 18)
1. Remove the old cartridge.
Twist the knob of the cartridge counter clockwise.
When the cartridge is removed, you will feel it click .
Pull out the cartridge.
NOTE: There will be some water(25cc) in the filter
cartridge. Some spilling may occur. Catch it in a
bowl or towel.
2. Replace with a new cartridge.
Take the new cartridge out of its packaging and remove the
protective cover from the o-rings.
With the cartridge knob in the vertical position, push the
new filter cartridge into the cover until it stops.
If you can’t turn the filter from side to side, it isn’t fully
inserted. Push it in firmly and twist it into place. You will
hear the snap when it clicks into place.
Using the handle, twist the cartridge clockwise about 1/4
turn.
3. After replacing filter, dispense water through the water
dispenser for 3 minutes to purge the system.
There may be a little air in the line, causing noise or
hissing. Run the water at the dispenser until the hissing
stops.
NOTE: - To purchase replacement water filter cartridges,
visit your local appliance dealer or part distributor,
or call 1-877-714-7486.

Ice Maker
1) How to Control the Amount of Water Supplied to Icemaker.
Caution : •Do not put hands or tools into the chute to confirm the operation of geared motor.
It may damage the refrigerator or hurt your hands.
To gain access to the ice maker, remove the ice bin in the upper part of the freezer compartment. Then use the water
control switch to change the amount of water supplied to the ice maker.

The water amount will vary depending
on the Water Control Switch setting as
well as the water pressure of the
connected water line.

wwWARNING
Personal Injury Hazard
Avoid contact with the moving parts of the ejector
mechanism or with the heating element that releases
the cubes. DO NOT place fingers or hands on the
automatic icemaking mechanism while the refrigerator
is plugged in.
2) Operating instructions
A newly-installed refrigerator may take up to 24 hours
to begin making ice.
The icemaker will produce eight cubes per
cycle—approximately 120–150 cubes in a 24-hour period,
depending on freezer compartment temperature, room
temperature, number of door openings and other operating
conditions.
If the refrigerator is used before the water connection is
made to the icemaker, set the power switch to O (off).
When the refrigerator has been connected to the water
supply, set the power switch to I (on).
The icemaker will fill with water when it cools to freezing. A
newly-installed refrigerator may take up to 24 hours to
begin making ice cubes.
Throw away the first few batches of ice to allow the water
line to clear.
Be sure nothing interferes with the sweep of the feeler arm.
When the bin fills to the level of the feeler arm, the
icemaker will stop producing ice.
It is normal for several cubes to be stuck together.
If ice is not used frequently, old ice cubes will become
cloudy, taste stale, and shrink.
NOTE: If the cube size is smaller or larger than you
expected, you can regulate the size with the cube size
button. (normally caused by variations in water pressure.)
Every time you press the cube size button, the indicator
light goes up. The higher the position indicated, the larger
the cubes will be. (1st step is the next after the 5th step.)
3) When you should set the icemaker power
switch to O (off)
•When the water supply will be shut off for several hours.
•When the ice storage bin is removed for more than a
minute or two.
•When the refrigerator will not be used for several days.
4) Normal sounds you may hear
•The icemaker water valve will buzz as the icemaker fills
with water. If the power switch is in the I (on) position, it
will buzz even if it has not yet been hooked up to water.
To stop the buzzing, move the power switch to O (off).
NOTE: Keeping the power switch in the I (on) position
before the water line is connected can damage the
icemaker.
•You will hear the sound of cubes dropping into the bin
and water running in the pipes as the icemaker refills.
5) Preparing for Vacation
Set the icemaker power switch to O (off) and shut off the
water supply to the refrigerator.
If the ambient temperature will drop below freezing, have a
qualified servicer drain the water supply system (on some
models) to prevent serious property damage due to
flooding from ruptured water lines or connections.

2. Refrigerator Functions
2-1-1. Temperature Selection (GR-L267, G267, P277 LCD DISPLAY)
* The temperature can vary ±3 °C depending on the load condition.
❉Whenever pressing the button, setting is repeated in the order of (Medium) ➝(Medium Cold) ➝(Coldest) ➝(Warmest) ➝
(Medium Warm).
• The actual inner temperature varies depending on the food status, as the indicated setting temperature is a target
temperature, not the actual temperature within the refrigerator.
• A newly installed refrigerator will take 24 hours minimum for temperatures to stabilize. The temperature should be
checked and adjusted as necessary after 2 or 3 days.
2-1-2. LCD Back Light Control (GR-L267, G267, P277)
1. In order to see the LCD display more easily, the backlight is turned on for one minute at the initial application of power, for
20 seconds when buttons are pressed, when a door is opened, and for 20 seconds after the door is closed.
2. When any display button is pressed while the backlight is off, the bell sounds and the backlight is turned on, but the
button function is not performed. In other words, pressing any button turns on the backlight but does not cause any
function to be initiated.
3. To check the LCD graphic and back light ON/OFF status, press and hold the EXPRESS/JET FRZ and FREEZER buttons.
This will turn the back light on and illuminate all of the graphics. When the buttons are released, the graphic display
returns to its previous setting and the back light is turned off.
2-1-3. Room temperature display function
1. The sensor for the ROOM TEMP display is located under the upper right hinge cover. Factors such as air flow, lighting,
and other appliances operating within the room, may cause the display to differ from other temperature displays in the
same room.
2. Ambient temperature is displayed between -9°C and 49°C. Temperatures -10°C and below are displayed as Lo and
temperatures 49°C and above are displayed as Hi. If the ambient temperature sensor fails, Er will be displayed.
