1. Turn the levelling leg clockwise to raise thatside of the appliance or counterclockwise tolower it.
2. Open the doors and check to make sure that they close easily.

NOTE

• Leveling the doors may not be possible when the floor is not leveled, or is of weak or poor construction.
• The refrigerator is heavy and should be installed on a rigid and solid surface.
• Some timber flooring may cause levelling difficulties if it flexes excessively.

Turning on the Power
Connecting the Appliance
To turn on the appliance, connect the power plug into the outlet socket. Do not double up with other appliances on the same outlet.
NOTE

• After connecting the power supply cord (or plug) to the outlet, wait 3 or 4 hours before you put food into the appliance. If you add food before the appliance has cooled completely, your food may spoil.
• To turn off the appliance, disconnect the power plug from the outlet socket.

Moving the Appliance for Relocation
Preparing for Relocation

1. Remove all food from inside the appliance.
2. Pull the power plug out, insert and fix it into the power plug hook at the rear or on top of the appliance.
3. Tape parts such as shelves and the door handle to prevent from falling off while moving the appliance.
4. Move the appliance with more than two people carefully. When transporting the appliance over a long distance, keep the appliance upright.
5. After installing the appliance, connect the power plug into a mains outlet socket and switch it on.

Before Use
Notes for Operation

• Users should keep in mind that frost can form if the door is not closed completely or if the humidity is high during the summer.
• Ensure there is sufficient space between food stored on the shelf or door basket to allow the door to close completely.
• Opening the door for long periods can cause a significant increase of the temperature in the compartments of the appliance.
• If the refrigerating appliance is left empty for long periods, switch off, defrost, clean, dry, and leave the door open to prevent mould developing within the appliance.
• Note that a temperature rise after defrosting has a permissible range in the appliance specifications. If you wish to minimise the impact on the food storage due to a temperature rise, seal or wrap the stored food in several layers.

Door Open Alarm
The alarm sounds 3 times in 30 second intervals if the fridge door is left open or not completely closed for 1 minute.
NOTE

• Contact the LG Electronics customer information centre if the alarm sound continues even after closing all doors.

Failure Detection
The appliance can automatically detect problems during the operation.
NOTE

• If a problem is detected, the appliance may not operate and an error code is displayed even when any button is pressed.
• If an error code is indicated on the display, do not turn off the power. Immediately contact the LG Electronics customer information centre and report the error code. If you turn off the power, the repair technician from the our information centre may have difficulty finding the problem.

Suggestion for Energy Saving

• For the most efficient use of energy, keep all inner parts (e.g. door bins, drawers and shelves) on their original location.
• Ensure there is sufficient space between stored foods. This allows cold air to be circulated evenly and lowers electricity bills.
• Store hot food only after it has cooled in order to prevent dew or frost.
• When storing food in the freezer compartment, set the freezer temperature lower than the temperature indicated on the food.
• Do not set the temperature of the appliance lower than needed.
• Do not put food near the temperature sensor of the fridge compartment. Keep a distance of at least 3 cm from the sensor.

Storing Foods Effectively

• Food may freeze or spoil if stored at the wrong temperature. Set the refrigerator to the correct temperature for the food being stored.
• Store frozen food or refrigerated food inside sealed containers.
• Check the expiration date and label (storage instructions) before storing food in the appliance.
• Do not store food for a long period of time if it spoils easily at a low temperature.
• Do not place unfrozen food in direct contact with food that is already frozen. It could be necessary to reduce the quantity to be frozen if freezing every day is anticipated.
• Place the refrigerated food or frozen food in each fridge or freezer compartment immediately after purchasing.
• Store raw meat and fish in suitable containers in the refrigerator, so that it is not in contact with or drip onto other food.
• Refrigerated foods and other food items can be stored on top of the vegetable drawer.
• Avoid refreezing any food which has been completely thawed. Freezing any food which has been completely thawed again will lower its taste and nutrition.
• Cool hot food before storing. If too much hot food is placed inside, the internal temperature of the appliance can increase and negatively affect other foods stored in the appliance.
• Do not overfill the appliance. Cold air can not circulate properly if the appliance is overfilled.
• If you set an excessively low temperature for food, it may become frozen. Do not set a temperature lower than the required temperature for the food to be stored correctly.
• If there are chill compartments in the appliance, do not store vegetables and fruits with higher moisture content in the chill compartments as they may freeze due to the lower temperature.
• In the event of a blackout, call the electricity company and ask how long it is going to last.
  – You should avoid door openings while the power is off.
  – When the power supply gets back to normal, check the condition of the food.

Maximum Freezing Capacity

• Express Freeze function will allow the freezer to reach its maximum freezing capacity. This generally takes up to 24 hours and automatically switches off.
• Express Freeze must be switched on for 7 hours before fresh products are placed in the freezer compartment.
• To get better air circulation, insert all inner parts like baskets and shelves.

Freezing the Maximum Amount of Food

If large quantities of food are to be stored, all the freezer drawers shall be taken out of the appliance and the food shall be stacked directly on the freezer shelves in the freezer compartment.

CAUTION

• To remove the drawers, first remove the food from drawers and then pull out the drawers carefully. Not doing so could cause injury or damage to the drawers.

NOTE

• To get better air circulation, insert all drawers.
• The shape of each drawer may be different, insert in the right position.
