Add UV-Leak Detection Additive Using The Vas 6201 In The Refrigerant Circuit
Described in the following are instructions for how to pour the UV-leak detection additive into the refrigerant circuit using the - VAS 6201/1-. If the UV-leak detection additive is added to the refrigerant circuit with the help of other tools (that is with the A/C Service Station) read the applicable operating instructions.
Found here is the quantity of UV-leak detection additive required to be added for a refrigerant circuit with a refrigerant oil quantity of 100 to 150cm 3 using the - VAS 6201- (2.5 + /- 0.5 cm3 ). If the refrigerant oil capacity in the refrigerant circuit is greater, more UV-leak detection additive must be added (that is 5.0 + /- 0.5 cm3 for a refrigerant circuit with a refrigerant oil capacity of 250cm 3 . For the respective refrigerant oil capacity in the refrigerant circuit, refer to REFRIGERANT OIL CAPACITIES .
If the UV-leak detection additive is added to the refrigerant circuit with the help of other tools (such as with the A/C Service Station) read the applicable operating instructions and designated quantities of UV-leak detection additive.
