Maintenance and Care
12-9
• The rubber seals of the toilet should be cleaned regularly
with plain water and a lubricant for seals (not Vaseline or
any other vegetable fats) should be applied. Applying this
regularly to the washer of the valve and other seals in the
toilet will ensure that they stay flexible and function longer.
Do not pour any corrosive substances down the drains.
Do not pour boiling water down the drains. Corrosive
substances and boiling water damage drain pipes and
syphons.
The following applies for the sink and the cooker:
• Clean stainless steel parts with normal household cleaners
or special stainless steel cleansing agents.
The following applies for built-in equipment:
• 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 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 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!
