8-
Don't fili 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.
11-
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.
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.
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. 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 globe valves and they should be in a good
condition. lf 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 ifil electrical components are sealed to prevent the leakage of the
refrigerant and the fire caused by it. lf you have any question, please consult the manufac-
turer.
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 refrige-
rant 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 compres-
sor 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.
