SAFETY INSTRUCTIONS
Hint!
This manual must be carefully read
and understood prior to installing and
servicing the compressor (package)
General Safety
All service operations described in this servicema-nual are only to be carried out by well-trained/quali-
fied personnel and even then only after this service
manual has been read carefully and is fully under-
stood.
Personal safety
Observe all (inter)national and/or local safety stand-
ards, measures and regulations during reinstalling,repairing and connecting the compressor (package).
Mechanical safety
If the compressor does not have to be removed from
its base, it is advisable to put warning labels on vital
parts of the compressor saying that the plant is out-
of-operation and must not be started up.
If the compressor has to be opened for service,the
refrigerant has to be pumped down and the electricsupply has to be cut off.
After having run the initial 100 operating hours,it is
essential (in both new and modified plants) toreplace the red running-in discharge oil filter element
with the permanent grey filter element. Also replace
the running-in suction gas filter element.
Check the direction of rotation is correct before re-
starting the compressor.
