without an air filter. Air filters must be
checked regularly for dirt and damage and
replaced, if necessary. The air filters must
be changed at least every six months or
when the “Change Filter” message appears

re-commissioning.
Health hazard by leaking refrig-
erant and refrigerator oil:
The unit is designed so as to
ensure that the refrigerant will never come
into contact with the drinking water, even if
there is a leakage in the cooling circuit. In
the case of leakages, however, refrigerant
may enter the atmosphere.
•
Gases or vapours, do not inhale.
•
Avoid skin and eye contact.
Directly at the leakage point,
refrigerant may cause local frost-
bite at the corresponding parts
of the body. When working on the cooling
circuit, protective gloves must be worn!
