Inspection and maintenance
7.1 General
The air/water heat exchanger is a maintenance-free,
hermetically sealed system. The water circuit is
checked at the factory for leaks and subjected to a
function trial run.
The installed maintenance-free fan is mounted on
ball bearings, protected against moisture and dust,
and fitted with a temperature monitor. The life ex-
pectancy is at least 30,000 operating hours. The air/
water heat exchanger is consequently largely main-
tenance free. If dirt is present in the cooling water,
a filter must be fitted.
Maintenance interval: 2,000 operating hours.
Sequence of maintenance measures:
– Check the level of dirt.
– Cooling membranes soiled? Clean if necessary.
– Activate test mode; cooling function OK?
– Check the noise generation of the fan.
