carefully before performing any maintenance on the chiller unit.
To ensure that the chiller unit operates without problems throughout a long service life, the system of

tasks, which require the refrigeration system to be opened, must be performed by competent personnel.
Maintenance can be divided into:

in the filters, for instance.
Maintenance intervals are described in detail in the compressor manual.
