Grasso<br />
If an oil rectifier system is applied in the refrigeration<br />
system, the oil return line<br />
must be connected to the oil return connection.<br />
Never connect the oil rectifier return line to<br />
the suction line or to the suction gas filter.<br />
DO NOT ground through the compressor<br />
when arc welding<br />
Suspension of system pipework<br />
To eliminate vibration transmission to the system<br />
piping, the following is recommended:<br />
• Install all piping free of tension.<br />
• Secure the piping by clips or suspenders in two<br />
directions.<br />
• Install (stop) valves, piping <strong>and</strong> accessories such,<br />
that there is no load exerted on the compressor.<br />
A1.6 Connecting the power supply<br />
Before leaving the factory the compressor<br />
package is completely wired*. The connection to<br />
be made by the installer is between main power<br />
source <strong>and</strong> the Monitron CR (if ordered).<br />
Information about further electrical connections<br />
to be made (e.g. crankcase heater, drive motor<br />
starting equipment, thermal protection of drive<br />
motor, automatic start/ stop, motor current<br />
transducer <strong>and</strong> other external electrical devices)<br />
can be found in the order manual.<br />
* If the st<strong>and</strong>ard recommended Monitron CR is applied.<br />
A: INSTALLATION AND PREPARATION FOR USE<br />
A1.7 Earthing connections<br />
Grasso compressors <strong>and</strong> packages are equipped<br />
with litz-wires <strong>and</strong> earth connecting points.<br />
To avoid leakage current flowing through the<br />
components, disconnect all litz-wires when arcwelding.<br />
After all installation functions are<br />
completed, reconnect the litz-wires <strong>and</strong> ground<br />
the package to earth.<br />
A1.8 Separately delivered components<br />
Mount the separately delivered set-components<br />
e.g. oil charge <strong>and</strong> drain valve, according to the<br />
instruction enclosed in each individual set.<br />
