be removed.
After inserting the flare nut, flaring work is carried out.

If the refrigerant of the air conditioner leaks, it is necessary to discharge all the
●
refrigerant. Vacuum first, then
charge the liquid refrigerant into air conditioner
according to the amount marked on the name plate.
Please do not let other cooling medium, except specified one (R410A), or air
●
enter into the cooling circulation system. Otherwise, there will be abnormal
high pressure in the system casuing damage and possibly personal injuries.
