The compressor is not charged with oil,
therefore, DO NOT start the compressor
before it has been installed and prepared
according to the sections A1 and A2.
A1 INSTALLATION
This section contains instructions for the proper
installation of a Grasso compressor (package).
Before the compressor (package) is ready for the
initial start up, the installation instructions in the
following paragraphs must be followed:
1. The Compressor (Package) should be levelled and
securely anchored to the foundation (see §A1.4).
2. All piping should be completed as in §A1.5.
3. The system and the compressor are to be pressure
tested for leaks (see §A2.1).
4. The system should be evacuated to remove air and
moisture (see §A2.2).
5. The electric wiring should be completed as per
wiring diagrams. Do not energize the main power
control cabinet until oil is added and the direction
of rotation has been checked.
6. The compressor is to be filled with the correct type
and amount of lubricating oil (see §A2.3).
7. The drive coupling or V-belt drive system should be
installed.
8. The system should be charged with the correct
amount of refrigerant.
9. The oil should be warmed up above minimum start
up oil temperature (see "Engineering Data").
10. The control cabinet or Monitron CR should be
energized to check the package control
(see §A2.5).
A1.1 Moving instructions and storage
For loose component or compressor package
weights, refer either to the relevant component
type plate or package lay-out or to the suppliers
document. For bare compressor weights, see
"Engineering Data".
Every precaution must be taken while
moving the package to its final location.
Pushing, pulling or climbing on any
package component or piping, can easily
create damage.
A1.1.1 Hoisting and moving instructions
Packaged base frame:
The only places that can be used for safe hoisting
of the package are the four hoisting eyes on the
steel base frame as shown in the above figure.
Prior to hoisting a compressor package with a
V-belt drive arrangement, the factory mounted
drive guard has to be removed. Attach spreader
bars to the slings so as to prevent damage to
piping and components.
DO NOT use the component hoisting
eyes to move the package!
These hoisting eyes are intended for
lifting loose components only and not for
the entire package!
