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 rapairing electric components.2. When connecting power cord, wait for more than five minutes after power cord was disconnected from the wall outlet.3. Check if the power plug or card is pinched between the refrigerator and the wall. If the cord is damaged, it could cause fire or electric shock.4. If the wall outlet is ocerloaded, it may cause a fire. Use a dedicated circuit for the refrigerator.5. Be sure the outlet is grounded. This is particulary important in wet or damp areas.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 full of water into the freezer. The contents will freeze and break the glass period.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.WARNINGS AND PRECAUTIONS FOR SAFETY- 3 -

3. HOW TO CONTROL THE AMOUNT OF WATER SUPPLIED TO ICEMAKER3-1. 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. Turn on the electricity after connecting water pipe.1) Press the test switch under the icemaker for two seconds as shown below.2) The bell rings (ding ~ dong), the ice tray rotates, and water comes out the icemaker water tube.3) The water is supplied into the tray two or three times. The amount is small each time. Put a container under the ice tray and press test switch.4) When the ice tray rotates,the water in it will spill. Collect the spilled water and discard it.5) When ice tray has finished rotation, water comes out the water tube. Check the amount that goes into the ice tray. (Refer to the drawing below. The optimum amount is 110cc. (Almost 4 oz.)).* It is acceptable is the adjusted water level is less than the optimum level.- 8 -

3-2 Control the amount of water supplied to the icemaker.Caution: • Unplug the power cord from the wall outlet and wait at least three minutes before removing the main PWB cover. 310 Volts are present in the control panel.Water Supplying Time Control Option1) The water supplying time is set at five seconds when the refrigerator is deivered.2) The amount of water supplied depends on the setting time and water pressure (city water pressure).3) If the ice cubes are too small, increase the water supplying time. This happens when too little water is supplied into the ice tray.4) If the ice cubes stick 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 the adjustment of the control switch for the amount of water supplied is complete, check the level of water in the ice.- 9 -SW2SW1OFF6.5sFACTORY SETTINGON5.5sOFF7.5sON8.5sWATER SUPPLY TIMESWITCHNOTEOFFONOFFON
