If you charge gaseous refrigerant,it may affect the capacity and reliability of the product as a result of change formation of the refrigerant. G Connect only the indoor units fit on R410A refrigerant. Check whether the indoor units can be connected with the product’s catalogue. (When incorrect indoor units are connected,they cannot operate normally.) Samsung Electronics...
Page 7: Warning
G If any gas or impurities except R410A refrigerant come into the refrigerant pipe, serious problem may occur and it may cause injury. G Make sure there is no leakage after installation. – Toxic gas may generate when refrigerant gas contacts with fire. G Leak test must be done using only Nitrogen(NO )gas. Samsung Electronics...
