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.
