Frequently Asked Questions - MU2R15 LG

What type of refrigerant does the LG MU2R15 air conditioner use?

The MU2R15 model uses R32 refrigerant, which is flammable. Follow specific safety instructions: do not pierce piping, store in a room without ignition sources.

How to properly install the outdoor unit?

Installation must be carried out by a certified professional. Respect minimum clearances: 300 mm on the front and sides, 600 mm at the back, 700 mm above. The location must support weight and vibrations, be protected from snow and salt.

What is the frequency of filter cleaning?

Filters should be cleaned every two weeks, or more often if necessary. Use water below 40°C and avoid harsh detergents. A dirty filter reduces efficiency and can cause malfunctions.

Can I use the air conditioner for heating?

Yes, the LG MU2R15 is a heat pump. It provides heating by reversing the cycle. Make sure the outdoor temperature is not too low (check the manual for limits).

What to do in case of refrigerant gas leak?

Immediately cut off power, ventilate the room by opening windows, do not touch electrical switches, and contact an authorized service. R32 is flammable, avoid any flame.

What is the maximum power consumption?

Consumption depends on capacity and conditions. The recommended circuit breaker is 15 to 25 A depending on the model (see label). For the MU2R15, a 20 A breaker is recommended.

How to use the remote control?

The remote control allows you to set temperature, mode (cool, heat, dehumidification, fan), fan speed, and timer. Replace batteries with new AAA batteries respecting polarity.

Can the outdoor unit be installed on a balcony?

Yes, provided the balcony is sufficiently sturdy, well-ventilated, and noise does not disturb neighbors. Respect minimum clearances and avoid direct exposure to sea wind.

What to do if the air conditioner does not start?

First check the power supply (breaker, outlet), remote control batteries, and that the selected mode is compatible (e.g., no heating if too cold). If the problem persists, contact a professional.

Is it necessary to have the air conditioner serviced every year?

Annual maintenance by a qualified technician is recommended to check circuit tightness, clean heat exchangers, and check pressures. This extends the lifespan and maintains efficiency.

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 level 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.

ELECTRICAL WIRING

- Follow the ordinances of your governmental organization for technical standards related to electrical equipment, wiring regulations, and guidance of each electric power company.

Connected to outdoor unit or B.D. unit.

WARNING

Be sure to have authorized electrical engineers do the electric work using special circuits in accordance with regulations and this installation manual. If the power supply circuit has a lack of capacity or electric work deficiency, it may cause an electric shock or fire.

Perform the electrical wiring work according to the electrical wiring connection.

• All wiring must comply with local requirements.
• Select a power source that is capable of supplying the current required by the air conditioner.
• Use a recognized ELCB (Electric Leakage Circuit Breaker) between the power source and the unit. A disconnection device to adequately disconnect all supply lines must be fitted.
• Model of circuit breaker recommended by authorized personnel only.

18 k/21 k/24 k 1 20 A
27 k/30 k 1 25 A

CAUTION

Be sure to connect the outdoor unit to earth. Do not connect the ground wire to any gas pipe, liquid pipe, lightning rod, or telephone earth line. If the earth is incomplete, it may cause an electric shock.

• Refer to the PDB for detailed electrical characteristics. - Connect the wires to the terminals on the control board individually according to the outdoor unit connection. - Ensure that the colors of the wires of the outdoor unit and the terminal numbers are the same as those of the indoor unit respectively. - When the connection line between the indoor unit and outdoor unit is over 40 m, connect the telecommunication line and power line separately. • The supply line of appliances shall not be lighter than polychloroprene sheathed (code designation 60245 IEC 57).

>6 and ≤10	1.0
>10 and ≤16	1.5
>16 and ≤25	2.5
>25 and ≤32	4
>32 and ≤40	6

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.

CONNECTING ELECTRICAL CABLES

- Follow the regulations of government organizations regarding technical standards for electrical equipment, wiring codes, and guidelines of electric power companies.

WARNING

Make sure that the installation of electrical wiring using special circuits is carried out by authorized electrical engineers in accordance with regulations and this installation instruction. If the power supply has insufficient capacity or other defects in the electrical lines, it may lead to electric shock or fire.

Related to the outdoor unit or B.D. unit

CAUTION

Make sure to connect the outdoor unit to the ground. Do not connect the grounding wire to any gas pipe, water pipe, lightning rod, or telephone line through the ground. If grounding is incomplete, it may lead to electric shock.

WARNING!

LIFTING METHOD

• When lifting the air conditioner, pass the lifting ropes under the base of the unit and use the two pairs of lifting points on the front and rear of the air conditioner.
• Always hold the ropes attached to the four points of the unit, and this will not damage the unit.
• Attach the ropes to the unit at an angle of 40° or less.

Minimum floor area (for R32)

• The unit must be installed, used, and stored in a room with a floor area larger than the minimum area.
• Use the following table to determine the minimum area.
• Console model (for YI market) must be installed in accordance with IEC 60335-2-40:2018 Edition 6.0.

ELECTRICAL CONNECTIONS

! WARNING

To carry out electrical work, contact qualified electrical engineers to install electrical wiring in accordance with national legislation on electrical wiring and this manual. If the voltage in the electrical circuit is less than the sufficient voltage, this can cause electric shock and thus endanger human life.

! CAUTION

Make sure that the outdoor unit is properly grounded. Do not connect the ground wire to a gas pipe, liquid pipe, lightning rod, or telephone line buried in the ground. If grounding is not fully implemented, it may cause electric shock.
