Skoda Citigo 2012 Workshop Manual page 55

– Park the vehicle in a darker area of the workshop (in daylight
or in case of strong lighting, the effect of the UV light is re‐
duced).
– Check the accessibility of the various components of the re‐
frigerant circuit and remove the parts in the surrounding area
of the refrigerant circuit, which obstruct the view of the com‐
ponents of the refrigerant circuit (e.g. the cover for the noise
insulation and the bumper).
– Always wear the safety goggles in order to protect your eyes.
– Connect the UV lamp to a 12-volt battery (vehicle battery). Pay
attention to the correct polarity of the connections.
– Switch on the UV lamp and inspect the components of the
refrigerant circuit. Points where refrigerant, refrigerant oil and
thus leak detection additive leaks out, will glow under UV light
(fluorescent).
Note
The leak detection additive can remain in the refrigerant circuit.
