STARTING & OPERATING PROCEDURES
PRESTART–UP INSTRUCTIONS – A new unit as re-
ceived from the factory has been prepared for shipping
only. Do not attempt to operate the unit until checked
and serviced as follows:
1. Compressor Oil – Check oil level in the reser-
voir. 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 Den-
ver AEON
t
4000 Lubricating Coolant which is
suitable for the first 6000 hours under normal op-
erating conditions. (AEON 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 bottom of the top sight 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.
Regular maintenance and replace-
ment at required intervals of the oil fil-
ter, air filter and air–oil separator is
necessary to achieve maximum ser-
vice and extended drain intervals of
AEON
t
4000 lubricant. Use only gen-
uine Gardner Denver filters designed
and specified for this compressor.
Before removing the oil filler plug, al-
ways stop the unit and release air
pressure, tag and lockout the power
supply to the starter. Failure to re-
lease pressure or properly discon-
nect 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 operating 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 in-
dicate the operating level
2. Air Filter – Inspect the air filter to be sure it is
clean and tightly assembled. Refer to Section 6,
“Air Filter,” page 33, for complete servicing
instructions. Be sure the inlet line, if used, is tight
and clean.
3. Piping – Refer to Section 2, “Installation,” page
8, and make sure piping meets all recommenda-
tions.
4. Electrical – Check the wiring diagrams fur-
nished with the unit to be sure it is properly wired.
See FIGURE 4–10 and FIGURE 4–11, page 24
and 25, for general wiring diagrams and Section
2, page 8 for installation instructions.
5. Grounding – The unit must be properly
grounded according to Section 250 of the Na-
tional Electrical Code.
Failure to properly ground the com-
pressor package could result in con-
troller malfunction.
6. Rotation – Check for correct motor rotation us-
ing “JOG MODE.” Compressor drive shaft rota-
tion must be clockwise standing facing the com-
pressor sheave. See Section 4, page 20, Step
8.
Operation with incorrect motor rota-
tion can damage equipment and
cause oil eruption from the compres-
sor inlet. When checking motor rota-
tion, induce minimum rotation (less
than one revolution if possible). Nev-
er allow motor to reach full speed.
