Commissioning
NOTICE
The machine is shipped without oil.
Operation without oil will ruin the machine in short time!
• Prior to commissioning, the machine must be filled with oil, see
Filling Oil [
}
10]
.
CAUTION
During operation the surface of the machine may reach temperatures of more than
70°C.
Risk of burns!
• Avoid contact with the machine during and directly after operation.
• Make sure that the installation conditions (see
Installation Conditions [
}
7]
) are com-
plied with.
• Make sure that the gas ballast valve is closed before starting the machine.
• Switch on the machine.
• Make sure that the maximum permissible number of starts does not exceed 12 starts
per hour.
• After few minutes of operation, check the oil level and top up if necessary.
As soon as the machine is operated under normal operating conditions:
• Measure the motor current and record it as reference for future maintenance and
troubleshooting work.
6.1 Continuous Operation
NOTICE
Working at a suction pressure higher than 100 hPa in continuous operation.
Oil will gush out from the exhaust and the machine will run out of oil very quickly!
Operation without oil will ruin the machine in short time!
• Limit the suction pressure in continuous operation.
If the machine is equipped with an oil mist separator:
• The operating time in continuous operation is not limited below a suction pressure
of 0.4 hPa.
In case of a higher suction pressure:
• The machine must be stopped for at least 5 minutes or operate at a pressure lower
than 0.4 hPa for at least 10 minutes within the maximum operating time (see
table below).
This operation allows the oil collected in the separator to return to the machine.
The following table gives reference values which may vary depending on the pumping
speed and the operating conditions.
