Section 3, Starting & Operating Procedures - Gardner Denver EBB BB-7.5 HP Operating And Service Manual

SECTION 3
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 – The oil must be checked be-
fore starting the unit and every 100 hours of opera-
tion. For instructions on checking the oil and the
proper oil level, refer to Section 5, page 24.
Do not mix different type oils. Unit is shipped filled
with Gardner Denver
Coolant which is suitable for the first 2000 hours
under normal operating conditions. AEON
and AEON 9000 SP are also available. Check
the decal on the reservoir to be sure which lubri-
cant is in the machine.
REPLACE OIL FILTER EVERY 1000 HOURS.
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 2000 lubricant. Use only gen-
uine Gardner Denver filters designed
and specified for this compressor.
Always stop the unit and release air
pressure before removing oil filler
plug. Failure to release pressure 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.
2. Air Filter – Inspect the air filter to be sure it is clean
and tightly assembled. Refer to Section 6, "Air Fil-
AEON 2000 Lubricating
4000
13–8–612
ter," page 30, for complete servicing instructions.
Be sure the inlet line, if used, is tight and clean.
3. Piping – Refer to Section 2, "Installation," and
make sure piping meets all recommendations.
4. Electrical – Check the wiring diagrams furnished
with the unit to be sure it is properly wired. See
FIGURE 4–8, page 23, for general wiring dia-
grams and Section 2, page 8 for installation
instructions. If the unit has optional integrated dry-
er, see Section 11, page 60.
5. Grounding – Unit must be properly grounded ac-
cording to Section 250 of the National Electrical
Code.
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 counterclockwise standing facing the
compressor 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.
7. System Pressure – The discharge pressure of
the unit is set at the factory. To change the dis-
charge pressure, set the controls to the desired
load pressure. DO NOT EXCEED THE MAXI-
MUM OPERATING PRESSURE ON THE COM-
PRESSOR NAMEPLATE. See Section 4, pages
19 through 21, "Programming the Load–Unload
Pressure Setpoints," for procedure.
