(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, and all the
stop valves on the equipment must be closed;
(11) Before purification and tests, the refrigerant recovered cannot be charged into another refrigeration system.

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

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 instructions 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.
