Frequently Asked Questions - CL09F LG

How to install the LG CL09F air conditioner?

Installation must be carried out by an approved professional in accordance with national electrical standards. Use the provided installation kit and respect the minimum distances indicated in the manual.

What type of refrigerant does this air conditioner use?

The LG CL09F uses refrigerant R32, which is flammable. Special precautions are required for installation and maintenance.

How to clean the air filter?

Turn off and unplug the unit. Remove the filter and wash it with cold water (40°C max) without harsh detergent. Let it dry completely before reinstalling. Clean every two weeks.

What to do if the air conditioner is not cooling properly?

Check that the air filter is not obstructed, that the air inlets/outlets are clear, and that the set temperature is appropriate. If the problem persists, contact after-sales service.

What do the displayed error codes mean?

Error codes are generated by the self-diagnosis system. Note the code and contact an approved technician. Do not attempt to repair yourself.

Can I use the air conditioner without the outdoor unit?

No, the CL09F is a split system with an indoor unit and an outdoor unit. Both are required for operation.

How to save energy with this air conditioner?

Close windows and blinds, set the temperature to a moderate level, clean the filter regularly, and use ventilation mode if necessary.

The air conditioner makes a water flowing noise, is this normal?

Yes, it is normal. This noise is caused by the circulation of refrigerant (freon) inside the air conditioner.

How to replace the remote control batteries?

Open the battery compartment, remove old batteries and insert two new batteries of the same type (usually AAA) respecting polarity (+/-). Do not mix new and used batteries.

What to do in case of refrigerant gas leak?

Immediately ventilate the room without using switches or flame. Turn off the power and contact after-sales service. R32 gas is flammable, avoid any ignition source.

MODEL DESIGNATION

Product information

• Product Name : Air conditioner
• Model Name:

• Additional Information: The serial number refers to the barcode on the product.
• Maximum allowable pressure High side: 4.2 MPa / 4.32 MPa (it can be different by model) Low side: 2.4 MPa

Airborne Noise Emission

The A-weighted sound pressure emitted by this product is below 70 dB.

** The noise level can vary depending on the site.

The figures quoted are emission levels and are not necessarily safe working levels.

Whilst there is a correlation between the emission and exposure levels, this cannot be used reliably to determine whether or not further precautions are required.

Factors that influence the actual level of exposure of the workforce include the characteristics of the work room and the other sources of noise, i.e. the number of equipment and other adjacent processes and the length of time for which an operator is exposed to the noise. Also, the permissible exposure level can vary from country to country.

This information, however, will enable the user of the equipment to make a better evaluation of the hazard and risk.

- Local supply

① Set anchor ② Plate washer - M10 ③ Spring washer - M10 ④ Nut - W3/8 or M10 ⑤ Suspension bolt - W3/8 or M10

Fixing Installation Plate

The wall you select should be strong and solid enough to prevent vibration.

1 Mount the installation plate on the wall with type "A" screws. If mounting the unit on a concrete wall, use anchor bolts.

- Mount the installation plate horizontally by aligning the centerline using Horizontal meter.

SK/SJ Chassis

SR Chassis

2 Measure the wall and mark the centerline. It is also important to use caution concerning the location of the installation plate. Routing of the wiring to power outlets is through the walls typically. Drilling the hole through the wall for piping connections must be done safely.

Installation of Indoor Unit

1. Hook the indoor unit onto the upper portion of the installation plate (engage the three hooks at the top of the indoor unit with the upper edge of the installation plate). Ensure that the hooks are properly seated on the installation plate by moving it left and right.

2. Unlock the tubing holder from the chassis and mount it between the chassis and the installation plate in order to separate the bottom side of the indoor unit from the wall.

* The feature can be changed according to the model type.

ELECTRIC WIRING WORK

General instructions

• All field-supplied parts and materials, and electric works must conform to local codes. Use copper wire only.
• Follow the "WIRING DIAGRAM" attached to the unit body to wire the outdoor unit, indoor units, and the remote controller.
• All wiring must be performed by an authorized electrician.

Wiring Connection

Connect the wires to the terminals on the control board individually according to the outdoor unit connection.

Ensure that the color of the wires of the outdoor unit and the terminal numbers are the same as those of the indoor unit respectively.

Connected to outdoor unit or B.D. unit.

• Open the control box cover and connect the remote controller cord and indoor power wires.
• Remove the control box cover to make the electrical connection between the indoor and outdoor units. (Remove screws ①)
• Use the cord clamper to secure the cord.

(1) Open the decor. (2) Unscrew the screw of the control box. (3) Slide up the metal plate cover. (4) Connect the connecting cable. (5) After connecting the cables, reassemble the metal plate cover with the screw.

* The feature may vary depending on the model type.

CAUTION

- The connecting cable between the indoor and outdoor units must comply with the following specifications (rubber insulation, type H05RN-F approved by HAR or SAA).

Rated current of appliance A.	Nominal cross-sectional area mm2
≤0.2>0.2 and ≤3>3 and ≤6>6 and ≤10>10 and ≤16>16 and ≤25>25 and ≤32>32 and ≤40>40 and ≤63	Tinsel cord0.50.751.0 (0.75)1.5 (1.0)2.54610
NOTE For supply cords supplied with multi-phase appliances, the nominal cross-sectional area of the conductors is based on the maximum cross-sectional area of the conductors per phase at the supply cord connection to the appliance terminals.

- If the supply cord is damaged, it must be replaced by a special cord or assembly available from the manufacturer or its service agent.

Precautions when laying power wiring

Use round pressure terminals for connections to the power terminal block.

Round pressure terminal

If none are available, follow the instructions below.

- Do not connect wires of different thicknesses to the power terminal block. (Loose power wiring may cause abnormal heat.)

- When connecting wires of the same thickness, do as shown in the figure below.

Connect wires of the same thickness to both sides.

It is forbidden to connect two wires to one side.

It is forbidden to connect wiring of different thicknesses.

For wiring, use the designated power wire and connect firmly, then secure to prevent outside pressure being exerted on the terminal block.

Use an appropriate screwdriver for tightening the terminal screws. A screwdriver with a small head will strip the head and make proper tightening impossible.

Over-tightening the terminal screws may break them.

MAINTENANCE

Clean the product regularly to maintain optimal performance and to prevent possible breakdown.

CAUTION

• Turn off the power and unplug the power cord before you perform any maintenance; otherwise it may cause electric shock.
• Never use water that is hotter than 40 °C when you clean the filters. It may cause deformation or discoloration.
• Never use volatile substances when you clean the filters. They may damage the surface of the product.

Operation Tips!

• Do not overcool the room. This is not good for the health and wastes electricity.
• Keep blinds or curtains closed. Do not let direct sunshine enter the room when the air conditioner is in operation.
• Keep the room temperature uniform. Adjust the vertical and horizontal airflow direction to ensure a uniform temperature in the room.
• 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.
• Clean the air filter regularly. Blockages in the air filter reduce the airflow and lower cooling and dehumidifying effects. Clean at least once every two weeks.
• Ventilate the room occasionally. Since windows are kept closed, it is a good idea to open them and ventilate the room now and then.

When the air conditioner is not going...

When the air conditioner is not going to be used for a long time.
