Condensation liquid tank, condenser, brand Modine: Removing and installing.
  Note
t  Inside the tank that has been removed, there is refrigeration oil that must be added to the refrigeration circuit (with the new tank) → Air conditioning - with refrigerant R134a SEAT.
t  Adjustment of oil quantity depends on nature of complaint.
t  If, for example, reservoir has been damaged in an accident (no loss of refrigerant, no penetration of moisture and dirt into refrigerant circuit), air conditioner can be serviced by weighing old and new reservoir without the need for extensive repair work. Pour refrigerant oil into new receiver until it weighs the same as the receiver removed.
t  If an indeterminate amount of refrigerant oil has escaped or dirt and moisture have penetrated into refrigerant circuit, it must be cleaned using compressed air and nitrogen → Air conditioning - with refrigerant R134a SEAT.
