Operating Instructions
oil needs to be added, make sure all pressure
is relieved before opening fill port. Use only
EMAX lubricating oil. Also make sure oil level
does not drop below low level line on site
glass during operation. If it does, stop com-
pressor immediately, let rest for 10 minutes,
then add oil.
Air/Oil Separator tank is a
pressurized component. To avoid
serious injury, be sure system
pressure is relieved before
removing fill plug. Be aware oil
temperature may be very hot. Use
caution when opening fill plug.
Use only EMAX oil, model no.
AROL8000G1. For food
manufacturing applications, use model no.
AROLFOODG1. Use of any other product will cause
product damage and void the warranty. Refer to
warranty statement for oil requirements.
4. If compressor has sat idle for some time, add
approx. 0.5 L of EMAX Rotary Screw lubricat-
ing oil to suction valve. Then hand rotate
compressor several times to prevent equip-
ment damage. Check to ensure no foreign
matter has entered the system.
5. Make sure shipping brackets have been re-
moved. Refer to figure 2 in installation section.
6. Ensure all pipes and plugs are tight before
starting compressor.
Start Up
1. Slightly open drain valve on air/oil separator
tank to drain any condensed water. Failure to do
this will shorten service life of lubricating oil and
destroy the bearings. Be sure to close valve after
draining water.
2. Check “Emergency Stop” function by pressing the
button shortly after pressing ON button.
3. Do not operate the machine if there is any ab-
normal noise or vibration during operation. Call
EMAX service for assistance.
4. Press ON button to begin operation. After unit
starts, a time delay of approximately 5 seconds
will occur and a “LOADING” message will display
on PLC screen. This means the pump is operating
and the compressor is building pressure.
5. Monitor display panel for normal readings
such as amp draw and voltage. Push OFF but-
ton if there are any abnormal sounds, vibra-
tion or oil leakage.
6. Check that oil exhaust temperature is main-
tained between 160˚ - 180˚ F (70˚ - 95˚ C).
Cooling fan will cycle as needed to cool oil
temperature.
7. After OFF button is pressed, the motor will
continue to run for approx. 10-15 seconds
and blow down valve will automatically dis-
charge pressure from air/oil separator tank.
This is to prevent the air compressor from
stopping under heavy-load.
8. Record these instrument readings on a regu-
lar basis and retain for future reference:

Storage
1. If the machine is stopped for over three
weeks:
a) Wrap electrical equipment such as the con-
trol panel with plastic or oil paper to avoid
condensation.
b) Completely drain water in the oil cooler, the
back cooler and the oil/air separator tank.
c) Make sure any unsafe conditions are clearly
stated or repaired.
2. If the machine is not run for more than two
months:
a) Seal all ports to prevent moisture or dust
accummulation.
b) Wrap safety valve and control panel with
oil paper or an equivalent to avoid rust.
c) Replace lubricating oil then run machine
for 30 minutes. Drain condensed water
in the oil / air separator tank and the oil
cooler 2-3 days later.
d) Move machine to a clean, dry place.
Restarting Procedure
1. Remove any wrappings from system compo-
nents.
2. Ensure electric motor is properly insulated.
3. Perform initial checks then follow procedures
for start up.
