5 In case the vacuum state cannot be reached vacuumizing shall be carried out from numerous positions to pump the refrigerant in each part of the system out 6 It shall be guaranteed that the capacity of cylinders is sufficient before recovery 7 The recovery equipment shall be started and operated as per the operation instructions of the manufacturer 8 The cylinder cannot be charged too full The refrigerant charged cannot exceed 80 of the capacity of cylinders 9 The maximum operating pressure of cylinders cannot be surpassed even only lasting for a short term 10 After refrigerant charging is completed the cylinder and equipment must be evacuated rapidly stop valves on the equipment must be closed 11 Before purification and tests the refrigerant recovered cannot be charged into another refrigeration system and all the Note The air conditioner shall be marked with dates and signature after being scrapped and the refrigerant is discharged It shall be guaranteed that the sign on the air conditioner can reflect the flammable refrigerant charged inside Recovery English During maintenance or scrapping the refrigerant inside the refrigeration system needs to be cleared It is recommended that the refrigerant be cleared thoroughly The refrigerant can only be charged into a dedicated cylinder the capacity of which shall match with the refrigerant amount charged in the whole refrigeration system All cylinders to be used are designated for the recovered refrigerant and labeled for that refrigerant Dedicated Cylinder for Refrigerant Recovery The cylinders shall be equipped with pressure relief valves and stop valves under favorable state The empty cylinder shall be vacuumized before usage and be kept under normal temperature if possible The recovery equipment shall always be under favorable working state and be equipped with operation instructions to facilitate information search The recovery equipment shall be applicable to the recovery of flammable refrigerant Moreover weighing apparatus under available state with measurement certificates shall be equipped In addition removable attachment joints free from leakage shall be used as the hose and shall always be under favorable state Whether the recovery equipment is under favorable state and is properly maintained and whether all the electrical components are sealed shall be checked before usage to avoid fire in case of refrigerant leakage If you have any question please consult the manufacturer The refrigerant recovered shall be delivered back to the manufacturer in appropriate cylinders with transporting instmctions being attached Mixing of refrigerant in recovery equipment especially the cylinders is not allowed During transporting the space in which the flammable refrigerant air conditioners are loaded cannot be sealed Anti static measures shall be taken for the transporting vehicles if necessary Meanwhile during the transporting loading and unloading of air conditioners necessary protective measures shall be taken to protect the air conditioner from being damaged During removal of the compressor or clearing of the compressor oil it shall be guaranteed that the compressor is vacuumized to a proper level to ensure no residual flammable refrigerant is left inside the lubricating oil The vacuumizing shall be completed before the compressor is delivered back to the manufacturer The vacuumizing can only be accelerated by heating the compressor housing through electrical heating Safety shall be guaranteed when the oil is discharged from the system 11
