DANGER
•
If compressed air, steam or water are directed against a
person, they may cause injuries.
Always wear an eye shield and safety shoes.
The outside of the radiators must be cleaned with a jet of com-
pressed air and, if necessary, with a low-pressure water or
steam washing cycle; the specific products available on the mar-
ket can be certainly used, provided that the instructions given on
the package are followed and that the washed parts are carefully
dried at the end of the operations.
IMPORTANT
☞
•
Do not use products containing oily substances, even if in
slight quantities, since these facilitate the adhesion of
dust, which affects the heat exchange adversely.
•
Clean the outside of the radiators whenever the radiator
or the heat exchanger are dirtied, even if accidentally, with
oil, diesel oil, greasy or oily substances.
•
If the machine is used in dusty places, clean the radiator
and the exchanger more frequently, in order to avoid any
clogging of the fins.
