5. 6 Be sure that any room where you are working is thoroughly ventilated 7 Use ONLY authorized refillable refrigerant tanks It requires the use of recovering tanks with a minimum of 27 6 bar working pressure 8 Do not overfill the storage tank Tank is full at 80 volume There should be enough space for liquid expansion overfilling of the tank may cause a violent explosion A scale or a 80 O F P Kit must be used to avoid over filling the storage tank 9 Do not exceed the working pressure of Recovering Tank cylinder 10 Do not mix different refrigerants together in one tank or they could not be separated or used 11 Before recovering the refrigerant the tank should achieve the vacuum level 0 1 mpa which is for purging non condensable gases Each tank was full of nitrogen when it was manufactured in the factory thus the nitrogen should be evacuated before the first use 12 When the recovery machine is not used all the valves should be closed Because the air or the moisture of the air may harm the recovery result and shorten the service life of the recovery machine 13 When using an extension cord it should be a 14AWG minimum and no longer than 7 62 meters 25feet or it may make the voltage drop and damage the compressor GENERAL SAFETY GUIDELINES 14 A dry filter must always be used and should replaced frequently And each type of refrigerant must have its own filter For the sake of assuring the normal operation of the
