●
After a few minutes of operation, perform an Oil Level Inspection [
➔
28].
●
After a few minutes of operation, perform a Cooling Liquid Level Inspection [
➔
29].
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 Conveying Condensable Vapours
The machine, equipped either with a gas ballast valve or a dilution gas system, is suitable for the
conveyance of condensable vapours within the gas flow.
If condensable vapours are to be conveyed:
START
●
Open the gas ballast valve* or the dilution gas system* (solenoid valve)
●
Warm up the machine
●
Wait 30 minutes
●
Open the inlet valve
●
Perform the process
●
Close the inlet valve
●
Wait 30 minutes
●
Close the gas ballast valve* or the dilution gas system* (solenoid valve)
END
* optional accessories
●
Continuously drain condensate from the condensate drain plug (CD) of the silencer (SI) (Optional).
6.2 Liquid Flushing Procedure
The machine can optionally be equipped with a liquid flushing device.
If after the application process a liquid flushing is required:
START
●
Reduce the motor speed to 10 Hz (minimum admissible frequency) with the inlet valve closed
●
Open the liquid flushing device (solenoid valve)
●
Adapt the flushing liquid flow according to the application requirements
●
The flushing duration depends on the application
●
Close the liquid flushing device
END
6.3 Gas Purging Procedure
The machine can optionally be equipped with a purge gas system.
If after the application process a gas purge is required, i.e. after a liquid flushing sequence or to
render the compression chamber inert:
START
●
Close the inlet valve
●
Open the purge gas (solenoid valve)
●
The flushing duration depends on the application (minimum 200 seconds to render the
machine inert)
●
Close the purge gas
