6. Before the start of the recovery, you should ensure that the capacity of the storage
tank is sufficient. Only a special refrigerant tank can be used when loading the
refrigerant into the storage tank. All tanks intended to be used for the recovery of
refrigerants should have a refrigerant identification (i. e. refrigerant recovery tank).
Storage tanks should be equipped with pressure relief valves and globe valves and
they should be in a good condition. If possible, empty tanks should be evacuated
and maintained at room temperature before use.
7. Start and operate the recovery equipment according to the manufacturer's
instructions. The recovery equipment should be kept in a good working condition
and equipped with equipment operating instructions for easy access. The equipment
should be suitable for the recovery of R32 refrigerants. Besides, there should be
a qualified weighting apparatus which can be normally used. The hose should be
linked with detachable connection joint of zero leakage rate and be kept in a good
condition. Before using the recovery equipment, check if it is in a good condition
and if it gets perfect maintenance. Check if the electrical components are sealed to
prevent the leakage of the refrigerant and the fire caused by it.
8. The recovered refrigerant shall be loaded in the appropriate storage tanks,
attached with a transporting instruction, and returned to the refrigerant
manufacturer. Do not mix refrigerant in recovery equipment, especially a storage
tank.
9. Do not fill the tank to its full capacity (the liquid injection volume does not exceed
80 % of the tank volume).
10. Even the duration is short, it must not exceed the maximum working pressure of the
tank.
1 1. After the completion of the tank filling and the end of the operation process, you
should make sure that the tanks and equipment should be removed quickly and all
closing valves in the equipment are closed. Put transport instructions on the tank.
Take anti electrostatic measures if necessary in transportation.
12. The recovered refrigerants are not allowed to be injected into another system before
being purified and tested.
Note: The identification should be made after the appliance is scrapped and
refrigerants are evacuated. The identification should contain the date and
endorsement. Make sure the identification on the appliance can reflect the flammable
refrigerants contained in this appliance.
13. When removing the compressor or clearing the compressor oil, make sure the
compressor is pumped to an appropriate level to ensure that there is no residual
R32 refrigerants in the lubricating oil. The vacuum pumping should be carried
out before the compressor is returned to the supplier. Ensure the safety when
discharging oil from the system.
