Suspension of system pipework
To eliminate vibration transmission to the system piping, the following is
recommended:
•
Install all piping free of tension.
•
Secure the piping by clips or brackets in two directions.
•
Install (stop) valves, piping and accessories such, that there is no load
exerted on the compressor.
1.2.7 Connecting the power supply
Information about further electrical connections to be made (e.g. crankcase
heater, drive motor starting equipment, thermal protection of drive motor,
automatic start/ stop and other external electrical devices) can be found in the
plant manual (not supplied by Grasso).
1.2.8 Earthing connections
Grasso compressors and packages are equipped with litz-wires and earth
connecting points.
To avoid leakage current flowing through the components, disconnect all litz-
wires when arc-welding. After all installation functions are completed, reconnect
the litz-wires and ground the package to earth.
1.2.9 Separately delivered components
Hint!
Check whether the sets/parts/components belonging to this
