8.
Don't fill 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 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.
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. 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
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.
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 perfect maintenance. Check if ll electrical components are sealed
to prevent the leakage of the refrigerant and the fire caused by it. If you
have any question, please consult the manufacturer.
4.
The recovered refrigerant shall be loaded in the appropriate storage tanks,
attached with a transporting instruction, and returned to the refrigerant
manufacturer. Don't mix refrigerant in recovery equipment, especially a
storage tank.
5.
The space loading R32 refrigeration can't be enclosed in the process of
transportation. Take anti electrostatic measures if necessary in
transportation. In the process of transport, loading and unloading,
necessary protective measures must be taken to protect the air
conditioner to ensure that the air conditioner is not damaged.
6.
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.
