The cartridge -A- contains 15.4 ml of UV-leak detection additive (one unit -B- corresponds to 2.5 ml).

-- Assemble the Leak Detection Kit - VAS6201A- item -1- with the cartridge item -2- - VAS6201/2- (See Figure).

-- Insert the Leak Detection Kit - Filler Tube VAS6201/8 (refer to item -7-) into the hand pump (See Figure).

-- 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 below.
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 below.
