Inspect refrigerant hoses and connections and make
sure that there are no signs of an oil film that can
indicate a refrigerant leakage.
The refrigerant contains tracing liquid, which makes it
possible to detect leaks with the aid of a UV lamp. If
the areas around the connections are strongly
coloured, this is an indication of a leak.

With the unit in operation, open the engine hood and
check using the sight glass (1) that bubbles are not
visible on the drying filter.
The filter is located on the right-hand side at the front
edge of the engine compartment. If bubbles are visible
through the sight glass, this is a sign that the
refrigerant level is too low. If so, stop the unit. The unit
may be damaged if it is run with insufficient refrigerant.
