REPLACEMENT OF OIL FILTERS
General
The frequency of exchanging oil discharge filter, oil suction filter and compressor
suction gas filter(s) depends on the condition of the refrigeration system. Besides
the maintenance schedules, it is recommended to exchange all filters when the
compressor is overhauled and also in case the refrigeration plant has been
modified.
Hint!
An oil discharge oil running-in filter is factory mounted. This oil filter
must be exchanged after max. 100 running hours. This oil filter cannot
be cleaned.
