Filling safty equipment (Gas Liquid Seperator) ---------------------------------------------------- ------ ---------- --Fig.4
In general, the refrigentrant must be converted to liquid, because refrigerant R410A is a mixed system,
if the combined ratio changes there will be a certain risk. In order to avoid the refrigerant return to
compressor in liquid, you can use this device to make refrigerant safely entering the compressor.
