    1. SAFETY PRECAUTIONS The important contents concerned to the safety are described on the product itself and on this Service Manual. Please read this Service Manual after understanding the described items thoroughly in the following contents (Indications/Illustrated marks), and keep them. 7 Warning indications on the air conditioner unit This mark is for R32 refrigerant only.
  • Page 4 CAUTION New Refrigerant Air Conditioner Installation • THIS AIR CONDITIONER ADOPTS THE NEW HFC REFRIGERANT (R32 WHICH DOES NOT DESTROY OZONE LAYER. R32 refrigerant is apt to be affected by impurities such as water, oxidizing membrane, and oils because the working pressure of R32 refrigerant is approx.
  • Page 5 WARNING About the refrigerant • This product contains uorinated greenhouse gases. • Do not vent gases to the atmosphere. • The appliance shall be stored in a room without continuously operating ignition sources (for example: open ames, an operating gas appliance or an operating electric heater).
  • Page 6 WARNING • Be sure to use only approved accessories or the speci ed parts. Failure to do so may cause the unit to fall, water leakage, re or electrical shock. • After the installation work, ensure that there is no leakage of refrigerant gas. If the refrigerant gas leaks out of the pipe into the room and is heated by re or something else from a fan heater, stove or gas range, it causes generation of poisonous gas.
  • Page 7 WARNING • In accordance with IEC60335-2-40 2018 a minimum oor area MUST be observed when installing the Multi System air conditioner. Follow the table below to calculate the minimum oor area for installed product. Minimum oor area, When combined with indoor product. (m Refrigerant BI-FLOW CONSOLE amount...
  • Page 8 CAUTION • Exposure of unit to water or other moisture before installation may result in an electrical short. Do not store in a wet basement or expose to rain or water. • Do not install in a place that can increase the vibration of the unit. Do not install in a place that can amplify the noise level of the unit or where noise or discharged air might disturb neighbors.
  • Page 9 CAUTION • Please read this installation manual carefully before installing the unit. It contains further important instructions for proper installation. • Exposure of unit to water or other moisture before installation could result in electric shock. Do not store it in a wet basement or expose to rain or water. •...
