Maintenance
6.1.1 Maintenance intervals
6.1.2 Daily operation
Prior to starting the machine, check the oil level in the
separator tank. (See Starting the compressor in the
Operation section.) Should the level be low, add the
necessary amount. If you need to add oil too frequently, it
may indicate that a problem has developed which is
causing this excessive loss. Refer to the Troubleshooting
section (excessive coolant consumption) for a probable
cause and remedy.
After a routine start has been made, observe the machine
and monitor whether correct readings for that particular
phase of operation are being displayed. Good practice is to
perform a general check on the overall machine and
instruments after the machine has warmed up, to ensure
that the compressor is running properly.

NOTE
The above lifetime guidelines are applicable only to standard operating and regular maintenance conditions recommended in
this manual. In the event of changes in the conditions, consult ELGi.
Do not remove caps, plugs, or other components when the
compressor is running or pressurized. Stop the compressor
and relieve all internal pressure before doing so.
