(package)

General Safety
All service operations described in this
servicemanual are only to be carried out by
well-trained/qualified personnel and even then
only after this service manual has been read
carefully and is fully understood.

Personal safety
Observe all (inter)national and/or local safety
standards, 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
frigerant has to be pumped down and the electric
supply has to be cut off.
After having run the initial 100 operating hours,it is
essential (in both new and modified plants) to
replace the red running-in filter element with the
permanent filter element supplied.
On reinstalling a compressor, it should be checked
whether the direction of rotation of the compressor
has remained the same.
