General
A "Preventive maintenance" must be performed at
least once every year as long as the unit is not used
more than normal. Normal operation is estimated to
correspond to approx. 5.000 hours of operation.
In some parts of the Preventive maintenance, as
described in this chapter, the software Field Service
System (FSS) is a requirement.

but not covered by this Service Manual, may also
demand maintenance actions. Refer to the equipments
documentation. These units can e. g. be:
• Humidifier equipment.
• Other optional equipment.

cleaned before performing any maintenance; routine
