Cleaning the components with com-
pressed air
After removing the cover from the unit, you will be able
to access the components in the outer circuit, particu-
larly the condenser, the condenser fan and the com-
pressor chamber.
Wear cut-resistant gloves when cleaning with com-
pressed air, so as to avoid injuries caused by sharp
edges inside the unit.
When cleaning the components with compressed air,
blow dirt sideways out of the cooling unit.
Alternatively, use a suitable vacuum cleaner to clean all
components.
