16 OPERATION

OPERATION

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.

Door Open Alarm

The alarm sounds 3 times in 30 second intervals if the 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, make sure that door bins, drawers and shelves are assembled properly.
  • 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.
  • 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.
  • The automatic defrosting system in the appliance ensures that the compartment remains free of ice buildup under normal operating conditions.

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.

LG GC-B257SMZV - Storing Foods Effectively - 4

Pure geometric diagram with intersecting lines and shapes, no text or symbols present.

  • 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 may be necessary to reduce the quantity to be frozen if freezing every day is anticipated.
  • Place the refrigerated 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.
  • Do not overfill the appliance. Cold air cannot circulate properly if the appliance is overfilled.
  • 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.
  • 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.

NOTE

  • The max freezing capacity of your appliance is stated on the rating label inside the fridge compartment.
  • For maximum freezing capacity, set the freezer temperature to the coldest temperature setting.

Freezing the Maximum Amount of Food

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

LG GC-B257SMZV - Freezing the Maximum Amount of Food - 1

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

- The shape of each drawer may be different, insert in the right position.

30 MAINTENANCE

MAINTENANCE

Cleaning

General Cleaning Tips

  • Performing manual defrosting, maintenance or cleaning of the appliance while food is stored in the freezer can raise the temperature of the food and reduce its storage life. • Regularly clean any surfaces that can come in contact with food.
  • When cleaning the inside or outside of the appliance, do not wipe it with a rough brush, toothpaste, or flammable materials. Do not use cleaning agents containing flammable substances. This may cause discolouration or damage to the appliance.
  • Flammable substances: alcohol (ethanol, methanol, isopropyl alcohol, isobutyl alcohol, etc.), thinner, bleach, benzene, flammable liquid, abrasive, etc. • After cleaning, check if the power cable is damaged.

Cleaning the Exterior

  • When cleaning the outside air vents of the appliance by means of vacuuming, then the power cord should be unplugged from the outlet to avoid any static discharge that can damage the electronics or cause an electric shock. Regular cleaning of the rear and side ventilation covers is recommended to maintain reliable and economical operation of the unit.
  • Keep the air vents on the exterior of the appliance clean. Blocked air vents can cause fire or appliance damage.
  • For the appliance exterior, use a clean sponge or soft cloth and a mild detergent in warm water. Do not use abrasive or harsh cleaners. Dry thoroughly with a soft cloth. Do not use contaminated cloths when cleaning the stainless steel doors. Always use a dedicated cloth and wipe in the same direction as the grain. This helps reduce surface staining and tarnishing.

Cleaning the Interior

  • When removing a shelf or drawer from inside the appliance, remove all stored foods from the shelf or drawer to prevent injury or damage to the appliance. Otherwise, injury may occur due to the weight of stored foods.
  • Detach the shelves and drawers and clean them with water, and then dry them sufficiently, before replacing them. • Regularly wipe the door gaskets with a wet soft towel.
  • Door basket spills and stains should be cleaned as they can compromise storage ability of the basket and could even be damaged.
  • Never clean the shelves or containers in the dishwasher. The parts may become deformed due to the heat.
  • The automatic defrosting system in the appliance ensures that the compartment remains free of ice buildup under normal operating conditions. Users do not need to defrost it manually.

Cleaning the Condenser Cover

Use a vacuum cleaner with a brush to clean the condenser cover and vents. Do not remove the panel covering the condenser coil area. We recommend that this be done every 12 months to maintain operating efficiency.
