• Make sure there is enough gas in the cooling circuit. Because if you load too little, oil lubrication will not be enough and may burn the compressor.
• However, charging too much gas will also cause damage to the air-conditioning system such as: consuming gasoline, not cold enough, engine too hot, ....
• Only open and close the low pressure valve. By opening the high pressure gas will run in the opposite direction and make the switch interrupted.
• Gas should be loaded in the form of gas, because if you fill the gas upside down when the tank is turned upside down, it will make the gas easier to compress, resulting in a compressor breakage.
