SECTION 3
STARTING & OPERATING PROCEDURES
PRESTART–UP INSTRUCTIONS – A new unit as re-
ceived from the factory has been tested and then pre-
pared for shipping only. Do not attempt to operate the
unit until checked and serviced as follows:
1.
Compressor Oil – Check the 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. The unit is shipped filled with Gardner Denver
AEON
t
9000 SP Lubricating Coolant which is
suitable for the first 8000 hours under normal op-
erating conditions.
REPLACE OIL FILTER EVERY 1000 HOURS.
Initial fill, or filling after a complete draining of the
system, may show the oil level in the yellow “EX-
CESS OIL” range. After start–up, the oil will fall
into the green operating range as system compo-
nents are filled. If necessary, add oil to bring the
level to the top of the green range as read when
the unit is operating at full load and normal pres-
sure. See FIGURE 5–5, page 38.
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
9000 SP synthetic lubricant.
Use only genuine Gardner Denver fil-
ters 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 res-
ervoir and the oil level may read higher than when
operating on load. DO NOT DRAIN OIL TO COR-
RECT; on the next loaded cycle or start, oil will
again fill the system and the gauge will indicate the
operating level.
2.
Air Filter – Inspect the air filter to be sure it is clean
and tightly assembled. Refer to Section 6, “Air Fil-
ter,” page 45, for complete servicing instructions.
Be sure the inlet line, if used, is tight and clean.
3.
Coupling – Check all bolts and cap screws for
tightness. See Section 7, page 47.
4.
Piping – Refer to Section 2, “Installation,” page
8, and make sure piping meets all recommenda-
tions.
5.
Electrical – Check the wiring diagrams furnished
with the unit to be sure it is properly wired. See
FIGURE 4–13 thru FIGURE 4–15, pages 30 thru
32, for general wiring diagrams and Section 2,
page 8 for installation instructions.
6.
Grounding – Equipment must be properly
grounded according to Table 250–95 of the Na-
tional Electrical Code.
Failure to properly ground the com-
pressor package could result in con-
troller malfunction.
7.
Rotation – Check for correct motor rotation using
“JOG MODE.” Compressor drive shaft rotation
must be clockwise standing facing the compres-
sor coupling.
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.
