-- Insert the Leak Detection Kit - Filler Tube :VAS6201/8 . Refer to Add UV-Leak Detection Additive using the in the Refrigerant Circuit - Leak Detection Kit - Filler Tube:VAS6201/8 -item 7- into the hand pump.

-- Open the hand pump service valve.

NOTE:

UV-Leak detection additive is best added to the empty refrigerant circuit via a service connection or an opened connection.

If the refrigerant circuit is empty, then it is better to add the UV-leak detection additive via a connection point (for example, when the connection point is already open). This way no UV-leak detection additive remains in the service connection and the connection does not need to cleaned.

Add the UV-leak detection additive to the refrigerant circuit via a service connection. Refer to Adding UV-Leak Detection Additive when the Refrigerant Circuit is Full .
Add the UV-leak detection additive to the refrigerant circuit via an opened connection. Refer to Add the UV-Leak Detection Additive to the Refrigerant Circuit via an Opened Connection .
