LG Multi V Series Manual

Selection of the best location
Install the air conditioner in the location that satisfies the following conditions.

1. Install declination of the indoor unit is very important for the drain of the duct type air conditioner.
2. Minimum thickness of the insulation for the connecting pipe shall be 5 mm.

Front of view

• The unit must be horizontal or declined to the drain hose connected when finished installation.
  

Drain test
The air conditioner uses a drain pump to drain water. Use the following procedure to test the drain pump operation:


The supplied flexible drain hose should not be strained. A strained hose may cause leakage of water.

• Connect the main drain pipe to the exterior and leave it provisionally until the test comes to an end.
• Feed water to the flexible drain hose and check the piping for leakage.
• Be sure to check the drain pump for normal operation and noise when electrical wiring is complete.
• When the test is complete, connect the flexible drain hose to the drain port on the indoor unit.
  

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. Factor 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 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.

Limiting concentration
Limiting concentration is the limit of Freon gas concentration where immediate measures can be taken without hurting human body when refrigerant leaks in the air. The limiting concentration shall be described in the unit of kg/m³ (Freon gas weight per unit air volume) for facilitating calculation
Limiting concentration: 0.44 kg/m³ (R410A)
