» Tip 1 – Functional check and visual inspection
Tests for pressure, tightness and damage to hoses and lines are performed to start with. It may then be possible to already identify initial causes for malfunctioning of the A/C system. Our sight glass enables visual inspection of the refrigerant or compressor oil and provides valuable information on its condition. For example, there may be chips or other foreign bodies in the system. It is also possible to check whether the compressor oil has become discoloured or whether water is present.
» Tip 2: The refrigerant
Refrigerant is responsible for functioning of the air conditioning system. As around 10% of refrigerant escapes each year through seals, connections or hoses, refrigerant must be regularly extracted and refilled. Legislation has set a maximum upper limit of 40 g for refrigerant loss in vehicles with one evaporator and 60 g for refrigerant loss in vehicles with two. If more refrigerant escapes per year, the A/C system has a leak. If there is a leak in the system, we recommend using our selective SelectH2 leak location set. Even the smallest leaks can be easily identified as the SelectH2 responds to forming gas with its acute sensor system. Further information on leak location can be found here.
