7.1 General
The cooling circuit is designed in the form of a main-
tenance-free, hermetically sealed system. The cool-
ing unit is filled with the required quantity of refriger-
ant at the factory, checked for leaks, and subjected
to a functional test run.
The installed maintenance-free fans are mounted on
ball bearings, protected against moisture and dust,
and fitted with a temperature monitor. The life expec-
tancy is at least 30,000 operating hours. The cooling
unit is thus largely maintenance-free. All that may be
required from time to time is to clean the components
of the external air circuit using a vacuum cleaner or
compressed air if they become visibly dirty. Any
stubborn, oily stains may be removed using a non-
flammable detergent, such as degreaser.
Maintenance interval: 2000 operating hours. Depen-
ding on the level of contamination in the ambient air,
the maintenance interval may be reduced to suit the
air pollution intensity.

During storage, the cooling unit must stand upright.
The closed cooling circuit contains refrigerant and oil
which must be properly disposed of for the sake of
the environment. Disposal can be performed at the
RITTAL plant.
