Winterising Your Motorhome - Hobby OPTIMA ONTOUR EDITION 2019 Manual

222 12. Maintenance and Care
• The safety / outlet valve (FrostControl) must be operated
regularly (at least twice a year) to remove lime deposits
and to ensure that it is not blocked.
• The space behind the refrigerator should be hoovered and
cleaned regularly. The ventilation grille should also be kept
clean. The door seal should be rubbed once a year with
talcum power to keep it supple and the expandable fold
should be checked for tears.
• The glycol mixture in the hot-water heating * system
should be replaced every two years, because certain pro-
perties such as protection against corrosion deteriorate.
• The filter in the fume hood* must be cleaned occasionally,
because cooking fat collects there. We recommend that you
use warm water with a bit of dishwashing liquid to clean it.
Remove all spray cans with cleaners and polishes from
the vehicle after finishing the upkeep! Otherwise, there is a
danger of explosion at temperatures over 50° C!
