NOTE:

Instructions for how to pour the UV-leak detection additive into the refrigerant circuit using the Leak Detection Kit -VAS 6201A- are given in the following. If the UV-leak detection additive is added to the refrigerant circuit with the help of other tools (for example, with the A/C service station) read the applicable operating instructions.

The following is the specified amount of UV-leak detection additive that is to be added to a refrigerant circuit with a refrigerant oil quantity of 100 to 150cm ³ using the Leak Detection Kit -VAS 6201A- (2.5 ± 0.5 cm³ ). If the refrigerant oil capacity in the refrigerant circuit is larger, then more UV-leak detection additive must be added accordingly (for example, 5.0 ± 0.5 cm³ for a refrigerant circuit with a refrigerant oil capacity of 250 cm ³ . For the relevant refrigerant oil quantities in the refrigerant circuit. Refer to Refer to APPROVED REFRIGERANT OILS AND REFRIGERANT OIL CAPACITIES .

If the UV-leak detection additive is added to the refrigerant circuit with the help of other tools (for example, with the A/C service station), observe the prescribed quantities of UV-leak detection additive given in the corresponding operating instructions.
