• Recommendations for maintenance and
inspection
Since dust collects after using the unit for several
years, the performance will be deteriorated to
some extent.
Disassembling and cleaning inside require techni-
cal expertise, so we recommend entering a main-
tenance and inspection contract (at a cost)
separate from normal maintenance.
