Request your dealer or a professional installer to install the unit in accordance with this Manual An improperly installed unit can cause serious accidents such as water leakage electric shock or fire If the unit is installed in disregard of the instructions in the Installation Manual it will void the manufacturer s warranty Do not turn ON the power until all work has been completed Turning ON the power before the work is completed can cause serious accidents such as electric shock or fire En 1 If refrigerant leaks while work is being carried out ventilate the area If the refrigerant comes in contact with a flame it produces a toxic gas Installation work must be performed in accordance with national wiring standards by authorized personnel only Except for EMERGENCY never turn off main as well as sub breaker of the indoor units during operation It will cause compressor failure as well as water leakage First stop the indoor unit by operating the control unit converter or external input device and then cut the breaker Make sure to operate through the control unit converter or external input device When the breaker is designed locate it at a place where the users cannot start and stop in the daily work This mark indicates procedures which if improperly performed might possibly result in personal harm to the user or damage to property Z CAUTION Read carefully all security inf
7. 2 1 Precautions for using the R410A refrigerant Z WARNING Do not introduce any substance other than the prescribed refrigerant into the refrigeration cycle If air enters the refrigeration cycle the pressure in the refrigeration cycle will become abnormally high and cause the piping to rupture If there is a refrigerant leakage make sure that it does not exceed the concentration limit If a refrigerant leakage exceeds the concentration limit it can lead to accidents such as oxygen starvation Do not touch refrigerant that has leaked from the refrigerant pipe connections or other area Touching the refrigerant directly can cause frostbite If a refrigerant leakage occurs during operation immediately vacate the premises and thoroughly ventilate the area If the refrigerant comes in contact with a flame it produces a toxic gas 2 2 Special tool for R410A Z WARNING To install a unit that uses the R410A refrigerant use dedicated tools and piping materials that have been manufactured specifically for R410A use Because the pressure of the R410A refrigerant is approximately 1 6 times higher than the R22 failure to use dedicated piping material or improper installation can cause rupture or injury Furthermore it can cause serious accidents such as water leakage electric shock or fire Tool name Contents of change Name and Shape Application Pressure is huge and cannot be
