STARTING & OPERATING PROCEDURES
PRESTART-UP INSTRUCTIONS - A new unit as
received from the factory has been prepared for ship-
ping only. Do not attempt to operate the unit until
checked and serviced as follows:
1.
ComPressor Oil - Check oil level in the reservoir.
Add Oil only if the oil level gauge reads in the red
"ADD OIL" range.
Do not mix different type oils.
Unit is shipped filled with Gardner Denver"
AEON '" 4000 Lubricating Coolant which is suitable
for the first 4000 hours under normal operating
conditions. AEON 'M 4000 is generally suitable for
use up to 6000 hours service life, provided the
lubricant is monitored by periodic analysis.
REPLACE OIL FILTER EVERY 1000 HOURS.
Initial fill, or filling after a complete draining of the
system, may show the oil level above the FULL
mark (the center of the gauge). After start-up, the
oil level will drop and fluctuate as the machine runs.
To check for proper oil level, shut off the machine
and allow the foam to settle out. if necessary, add
oil to bring the level to the FULL mark. See Figure
1-3,
page 3, Section 1,
NOTICE
Regular maintenance and replacement
at required intervals of the oil filter, air
filter and air-oil separator is necessary
to achieve maximum service and ex-
tended drain intervals of AEONTM 4000
petroleum base lubricant. Use only
genuine Gardner Denver filters
designed and specified for this com-
pressor.
DANGER
Before removing oil filler plug, always
stop the unit and release air pressure,
disconnect, tag and lockout the power
supply to the starter. Failure to release
pressure or properly disconnect the
power may result in personal injury or
death.
During unloaded operation and after shutdown, the
system will partially drain back into the oil reservoir
and the oil level may read higher than when operat-
ing on load. DO NOT DRAIN OIL TO CORRECT;
on the next loaded cycle or start, oil will again fill
the system and the gauge will indicate the operat-
ing level.

Air Filter - Inspect the air filter to be sure it is clean
and tightly assembled. Refer to Section 6, "Air
Filter,"for complete servicing instructions. Be sure
the inlet line, if used, is tight and clean.
Piping - Refer to Section 2, "installation,"and make
sure piping meets all recommendations.
Electrical - Check the wiring diagrams furnished
with the unit to be sure it is properly wired. See
Section 4, '[Controls and instruments," page 9, for
general wiring diagrams and Section 2 for installa-
tion instructions.
Grounding - Unit must be properly grounded ac-
cording to Section 250 of the National ELectrica
Code.
WARNING
Failure to properly ground the com-
pressor package could result in con-
troller malfunction.
6. Rotation - Check for correct motor rotation using
"JOG MODE." ComPressor drive shaft rotation
must be clockwise standing facing the compressor
sheave. See Section 4, page 5, STep8.
wARNING
Operation with incorrect motor rotation
can damage equipment and cause oil
eruption from the compressor inlet.
When checking motor rotation, induce
minimum rotation (less than oNe
revolution if possible). Never allow
motor to reach full speed.
7. System Pressure - Set the controls to the desired
load pressure. DO NOT EXCEED MAXIMUM
OPERATING PRESSURE ON COMPRESSOR
NAMEPLATE. See Section 4, pages 4 through 7,
"Controls and Instruments," for procedure.
