LG AK-W120LCB0 (01) PDF Document

Here are some tips to help you minimize power consumption when you use the LG AK-W120LCB0 air conditioner:

• Do not cool excessively indoors. This may be harmful to your health and may consume more electricity.

• Block sunlight with blinds or curtains while you are operating the air conditioner.

• Keep doors or windows closed tightly while you are operating the air conditioner.

• Adjust the direction of the air flow vertically or horizontally to circulate indoor air.

• Speed up the fan to cool or warm indoor air quickly, in a short period of time.

• Open windows regularly for ventilation as the indoor air quality may deteriorate if the air conditioner is used for many hours.

• Clean the air filter once every 2 weeks. Dust and impurities collected in the air filter may block the air flow or weaken the cooling / dehumidifying functions.

To ensure safe operation of your LG AK-W120LCB0, please follow these precautions:

• Always ground the product and install the control box cover securely to prevent fire or electric shock.

• Do not install the unit on a defective stand or in an area that may deteriorate with age to avoid the unit falling.

• Be cautious of sharp edges on the case, condenser, and evaporator fins during unpacking and installation.

Operation:

• Ensure the power cable cannot be pulled out or damaged during operation.

• Do not place anything on the power cable or operate the unit with wet hands.

• Do not allow water to run into electric parts.

• Do not store or use flammable gas or combustibles near the product.

• If you smell smoke or hear strange sounds, turn off the circuit breaker immediately.

• Ventilate the room from time to time, especially when used with a stove or other heating devices.

• Turn off the main power when cleaning the product.

• Do not expose your skin directly to cool air for long periods.

• Do not block the air inlet or outlet, as this can cause product failure.

• Do not touch metal parts when removing the air filter, as they are sharp.

1. Being exposed to direct airflow for an extended period of time could be hazardous to your health. Do not expose occupants, pets, or plants to direct airflow for extended periods of time.

2. Due to the possibility of oxygen deficiency, ventilate the room when used together with stoves or other heating devices.

3. Do not use this air conditioner for non-specified special purposes (e.g. preserving precision devices, food, pets, plants, and art objects). Such usage could damage the items.

1. Do not touch the metal parts of the unit when removing the filter. Injuries can occur when handling sharp metal edges.

2. Do not use water to clean inside the air conditioner. Exposure to water can destroy the insulation, leading to possible electric shock.

3. When cleaning the unit, first make sure that the power and breaker are turned off. The fan rotates at a very high speed during operation. There is a possibility of injury if the unit’s power is accidentally triggered on while cleaning inner parts of the unit.

The wired remote controller for the LG AK-W120LCB0 has several buttons and a display window with specific functions:

To select an operation mode, use the Left/Right buttons [<, >] on the main screen of the remote controller to highlight the operation mode category, then press the Up/Down buttons [∧, ∨] to choose your desired mode. Some products may not support all modes.

To use the Cooling Operation on your LG AK-W120LCB0:

1. Select the ‘Cool’ mode on the remote controller.

2. Set the desired temperature lower than the current indoor temperature. The indoor temperature is displayed on the default screen.

3. The setting temperature range for cooling mode is typically 18°C to 30°C (64°F to 86°F), but may be 20°C to 30°C (68°F to 86°F) for UAE models.

If the set temperature is higher than the room temperature, the unit will not start cooling until the room temperature exceeds the setpoint.

About the 3-minute delay function: After the cooling stops, the compressor will not restart immediately to protect itself. There is a 3-minute delay before the compressor starts and cold air is produced.

To use the Dry (dehumidification) Operation on your LG AK-W120LCB0, select the ‘Dry’ mode. In this mode, the initial fan speed is set to “Low”, and you cannot set a separate desired temperature. This mode is effective for removing moisture, especially during the rainy season or when humidity is high, and provides both dehumidification and cooling.

Before performing any maintenance, turn off the main power to the system. You can perform some periodic maintenance yourself:

• Cleaning Air Filters: This product has washable filters. It is very important to keep them clean. Inspect them at least once a month, or every week for the first 4 weeks in new buildings. Washable filters can be cleaned with a mild detergent and water. Ensure the filters are thoroughly dry before reinstalling them.

• Cleaning Condenser Coil: Unfiltered air can clog the condenser coil with dust and dirt. To clean the coil, vertically (along the fins) stroke the coil surface with a soft bristled brush.

• General Inspection: Keep all vegetation away from the condenser coil area and conduct a general unit inspection on a regular basis.

For more comprehensive checks, it is recommended that a qualified serviceman inspect the system at least once a year.

If you are not going to use your LG AK-W120LCB0 for an extended period, follow these steps:

1. Operate the air conditioner in air circulation (Fan Only) mode for 2 to 3 hours. This will dry out the internal parts.

2. Turn off the circuit breaker. This is important as dirt may collect and cause a fire if left on.

When you are ready to use the air conditioner again:

1. Clean the air filter and re-install it in the indoor side.

2. Check that the air inlet and outlet of the indoor/outdoor unit are not blocked.

3. Turn the circuit breaker back on.

• Do not overcool the room. This is not good for your health and wastes electricity.

• Keep blinds or curtains closed. Do not let direct sunshine enter the room when the air conditioner is in operation.

• Clean the air filter regularly. Blockages in the air filter reduce the airflow and lower cooling and dehumidifying effects.

• Make sure that the doors and windows are shut tight. Avoid opening doors and windows as much as possible to keep the cool air in the room.

• Ventilate the room occasionally. Since windows are kept closed, it is a good idea to open them and ventilate the room now and then.

If your LG AK-W120LCB0 does not operate, please check the following:

• Have you made a mistake in the timer operation? Check the reservation instructions.

• Has the fuse blown or has the circuit breaker been tripped? Check your electrical panel.

• Does the remote controller display “CH” on the LCD? This means a protective device has been tripped. Please contact your dealer or service center.

If you notice a peculiar odor, check that this is not a damp smell exuded by the walls, carpet, furniture, or cloth items in the room, as the air conditioner can circulate existing smells.

This is likely a normal occurrence. Condensation occurs when the airflow from the air conditioner cools the warm air in the room, causing moisture to form.

This is a normal function of the protection device of the air conditioner. This delay protects the compressor from damage. Please wait about three minutes, and the operation will begin.

If your LG AK-W120LCB0 is not cooling or heating effectively, check these points:

• Is the air filter dirty? A dirty filter can restrict airflow. See the air filter cleaning instructions.

• The room may have been very hot when the air conditioner was first turned on. Allow time for it to cool down or heat up.

• Has the setting temperature been set incorrectly? Ensure the cooling temperature is set lower than the room temperature, and the heating temperature is set higher.

• Are the unit’s air inlet or outlet vents obstructed?

If the remote controller display is faint or blank, check if the circuit breaker has been tripped. Reset it if necessary.

The LG AK-W120LCB0 has an Outage Compensation Function. It automatically retrieves the previous operating conditions when power is restored. You do not need to press any buttons. However, additional functions (like timers) will not be retrieved automatically.
