storage tank is suffi cient.
7. Start and operate the recovery equipment according to the manufacturer's
instructions.
8. Don't fi ll the tank to its full capacity (the liquid injection volume does not
exceed 80% of the tank volume).
9. Even the duration is short, it must not exceed the maximum working
pressure of the tank.
10. After the completion of the tank fi lling 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.
11. The recovered refrigerants are not allowed to be injected into another
system before being purifi ed and tested.
Note: The identifi cation should be made after the appliance is scrapped and
refrigerants are evacuated. The identifi cation should contain the date and
endorsement. Make sure the identifi cation on the appliance can refl ect the
fl ammable refrigerants contained in this appliance.
Recovery:
1. The clearance of refrigerants in the system is required when repairing or
scrapping the appliance. It is recommended to completely remove the
refrigerant.
2. Only a special refrigerant tank can be used when loading the refrigerant into
the storage tank. Make sure the capacity of the tank is appropriate to the
refrigerant injection quantity in the entire system. All tanks intended to be
used for the recovery of refrigerants should have a refrigerant identifi cation
(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.
3. 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 qualifi ed 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 all electrical components are sealed
to prevent the leakage of the refrigerant and the fi re caused by it. If you
have any question, please consult the manufacturer.
