Bare compressor or loose components:
Determine the dead weight of the par-
ticular component (see "Engineering
Data"), prior to moving a bare compres-
sor or loose component. Use the hoist-
ing eyes only to lift so, DO NOT sling
from other compressor parts (see figure
A1.1A).
Moving by fork-lift truck
The bare compressor or package can be
transported with a fork-lift truck with the forks
spread as much as possible between the skids. To
simplify moving, the 2 wooden transport beams
must still be mounted underneath the base frame
and stored in this way, untill the package is
positioned above its approximate location.
A1.1.2 Storage
The compressor (package) is filled with dry
nitrogen. Keep the system closed until the
package is
installed. If the compressor (package) is stored, it
should be kept at all times in a dry location to
prevent corrosion damage. If the compressor
(package) is to be stored for a prolonged period
of time, it should be checked weekly to ensure
that the holding charge of dry nitrogen remains
above atmospheric pressure.
A1.2 Required free space
For easy operating, servicing and maintenance
access, the compressor (package) should be at
least installed with sufficient free space around it.
A1.3 Foundation requirements
This paragraph covers measures to be taken for a
compressor (package) on a concrete floor.
Two foundation arrangements are described:
•
Compressor package with steel base frame
mounted on a concrete block.
•
Bare compressor direct mounted on a concrete
block via grouted machined anchors (see
"Engineering Data"). The mounting surfaces of
these machined anchors must be level without
any deviation and projecting at least 10 mm
above the concrete base.

PACKAGE TO BE MOUNTED ON A
CONCRETE BLOCK
On request, Grasso can calculate the
exact dimensions of the concrete block,
based on the compressor size and
operating conditions.
