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. Shut off the power
whenever replacing and repairing electric components.
2. When connecting power cord, please wait for more than
five minutes after power cord was disconnected from the
wall outlet.
3. Please check if the power plug is pressed by the
refrigerator against the wall. If the power plug was
damaged, it could cause fire or electric shock.
4. If the wall outlet is overloaded, it may cause a fire.
Please use a dedicated circuit for the refrigerator.
5. Please make sure the outlet is properly grounded.
Particularly in a wet or damp area.
6. Use standard electrical components.
7. Make sure hooks are correctly engaged.
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 was confirmed.
10. Do not touch the icemaker with hands or tools to
confirm the operation of geared motor.
11. Do not suggest that customers repair their 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, gas, or medicine 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 with full of water into the
freezer. The contents will freeze and break the glass
bottles.
15. When you scrap or discard the refrigerator, remove the
doors and dispose of it where children are not likely to
play in or around it.

3. How to Control the Amount of Water Supplied to Icemaker.
3-1. Confirm the amount of water supplied to the icemaker.
1. Pull out the ice bin shelf in the upper part of the freezer compartment.
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.
2. Apply electricity after connecting water pipe.
1) Press test switch under the icemaker for two seconds as shown below.
2) The bell rings(ding~dong) and ice tray rotates and water comes out from the icemaker water tube.
3) The water shall be supplied two or three times into the tray. The amount of water supplied for each time is small.
Put a water container under the ice tray and press test switch.
4) When ice tray rotates, the water in it will spill. Collect the spilt water and throw away into the sink.
5) When ice tray has finished rotation, water comes out from the water tube. Confirm the amounts of water in the ice tray.
(refer to fig. The optimum amount of water is 110cc)
* It is acceptable if the adjusted level of water is a bit smaller than optimum level.

3-2. Control the amount of water supplied to the icemaker.
Caution : •Please unplug the power cord from the wall outlet and wait for more than three minutes before disconnecting
PWB cover as 310V is applied in the control panel.
1. Disconnect PWB cover from the upper part of the refrigerator.
2. Adjust the amount of water supplied by using DIP switch.
■Water Supplying Time Control Option
1) The water supplying time is set at five seconds when the refrigerator is delivered.
2) The amount of water supplied depends on the setting time and water pressure (city water pressure).
3) If ice cube is too small, increase the water supplying time. This happens when too small water is supplied into the ice tray.
4) If ice cube sticks together, decrease the water supplying time. This happens when too much water is supplied into the ice tray.
Caution : When adjusting the amount of water supplied, adjust step by step. Otherwise the water may spill over.
3. When adjustment of control switch for the amount of water supplied is complete, check the level of water in the ice tray.
