To maximize the accessible work space needed for
compressor unit maintenance, both side panels
(drive assembly access panel and instrumentation
panel) must be removed. Consult
Section 6.4.1.2,
Removing and Replacing a Side Panel
to remove
the side panels.
Refer to
Figure 6-7

or seems slow in filling up tank, the valves may need
to be cleaned.

WARNING
Before performing maintenance:
Shut down machine, relieve all system
pressure and lock out all power, as per
the Safety Section of this manual. If
machine is hot, allow package to cool
before removing any panel.
NOTE THAT THE SYSTEM CAN BE
STARTED REMOTELY:
Always clearly tag the start-up
instrumentation against accidental
system start-ups during maintenance.
DANGER
Valves must be reinstalled in original
position. Incorrect valve replacement
may result in overpressure of the
cylinder head resulting in catastrophic
failure, injury or death. Valve gaskets
should be replaced each time valves are
serviced.
IMPORTANT
All valves should be removed from the
cylinder head every two (2) or three (3)
months of operation and examined for
cleanliness and carbon formation (build-
up).
