Maintenance
• The recovering of equipment and storage tank should comply with the relevant
national standards.
4. lf possible, the refrigerating system should be vacuumized.
5. lf the vacuum state can't be reached, you should extract the refrigerant in each
part of the system from many installation spots.
6. Before the start of the recovery, you should ensure that the capacity of the storage
tank is sufficient.
7. Start and operate the recovery equipment according to the manufacturer's
instructions.
8. Don't fill the tank to its full capacity (the liquid injection volume must not exceed
80%of the tank volume).
9. Even if the duration is short, it must not exceed the maximum working pressure of
the tank.
10.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
valves in the equipment are closed.
11. 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.
Recovery:
1. The clearance of refrigerants in the system is required when repairing or scrapping
the appliance. lt 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. AII 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 shut-off valves and
they should be in a good condition. lf possible, empty tanks should be 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 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
the proper maintenance. Check if the electrical components are sealed to prevent
the leakage of the refrigerant and the possibility of a deflagration. lf you have any
question, please consult the manufacturer.
4. The recovered refrigerant shall be loaded in the appropriate storage tanks,
