2.7 Transport and installation
Transport
A suitable forklift with sufficiently long forks must
be used to transport the compressor. Dependent
on type, the compressor weighs up to 4,700 kg /
10362 lbs.
Insert the forks only at the lifting points provided.
The compressor, even in its packed state, may not
be transported by crane.
During transport, no person may be present in
the hazard area. In particular, do not reach in or
allow the feet to pass beneath the suspended
compressor.
Installation / installation site
The compressor must be installed with full contact
on a foundation with sufficient structural strength.
The installation site (compressor room) must
be sized so that the compressor is sufficiently
accessible and the required cooling is ensured.
No flammable or explosive materials may be
stored near the compressor.
2.8 Normal operation
The compressor may be used only if it is in a
technically pristine state, and it must be used as
intended, with awareness of safety and hazards,
by following the operating instructions.
