INITIAL OPERATION CHECK
IMPORTANT:
Check motor rotation before operating the
compressor.
After confirming the correct direction of rotation for the main
motor and cooler fan, the compressor is ready to run for an
operation check.
With a valve installed at the outlet of the tank, close the valve
and isolate the tank from any pipeline system so only the
compressor tank will fill up with compressed air.
1. Turning the compressor on. Confirm position of E-stop.
White incoming power lamp (Power Indicator) should be on.
2. Turn the ON / OFF switch to the ON position. The green light
of the switch should be on. The compressor will start. If the
red high temperature / high pressure light is on, press it to
reset and the compressor will start.
3. Allow the compressor to run for approximately 5 minutes.
The pressure in the tank will rise as the compressor runs.
The following will take place:
a. When first turned on the air end will build up internal
pressure prior to sending air into the tank. This may take
15-20 seconds. You may notice a slight change in the
sound when the minimum pressure valve opens inside
the air end allowing air to flow into the tank.
b. Air pressure in the tank will rise until the pre-set
maximum pressure is reached. Upon reaching the
maximum pressure the compressor will switch to the
Unloaded Mode. The noise level will change to be quieter.
Air is no longer being pumped into the tank. The air
intake valve is now closed inside the air filter housing.
High pressure air from inside of the compressor housing
is vented slowly (Lasts about 1 minute) out through the
air filter housing to allowing the compressor to run at
idle. You may hear the high pressure air being vented for
about 1 minute. You may see a small amount of oil smoke
coming from the inlet. This is normal as a small amount
of oil may be released with the high pressure air.
Do not remove air fi lter housing or
perform any maintenance with pressure
in the air end or air pressure tank.
c. While the compressor is running look and listen for any
leaks with which may have developed during shipping
and handling.
RISK OF BURNS! Surfaces
and parts will become hot.
Operation
4. Allow compressor to run for approximately 5 minutes. Turn
off using the ON / OFF switch. Allow compressor to sit for at
least 1 minute while the high pressure air is released through
the compressor inlet. You will hear the air escaping.
Disconnect, tag and lock out
power source then release all
pressure from the system before attempting to install,
service, relocate or perform any maintenance.
5. Release all air pressure from the tank prior to performing any
maintenance or restarting the compressor for the next run
sequence in item #8.
6. Allow the compressor to cool, and then check the oil level.
Add oil if needed.
7. Seal any air or oil leaks if needed.
8. Restart air compressor. Check position of E-Stop. Turn
on main power. Turn ON / OFF switch to ON. Reset high
temperature / high pressure switch and the compressor will
start.
9. With valve at the tank outlet closed the air pressure will build
in the tank to the cut-out pressure. Air pressure in the tank
will rise until the pre-set maximum pressure is reached.
Upon reaching the maximum pressure the compressor will
switch to the Unloaded Mode. The noise level will change to
be quieter. Air is no longer being pumped into the tank. The
air intake valve is closed inside the air filter housing. High
pressure air from inside of the compressor housing is vented
slowly out through the air filter housing to allowing the
compressor to run at idle. You may hear the high pressure air
being vented for about 1 minute.
10. Inside the electrical box, the idle delay timer begins tracking
time. After approximately 15 minutes of operation at idle the
compressor will turn off.
11. Release pressure from the tank down to the cut-in pressure
and the compressor will automatically restart. Pressure
will build in the tank until the cut-out pressure and go into
unloaded mode again. Wait approximately 1 minute and
then release some air from the air tank.
When the pressure in the tank drops to the cut-in pressure the
air inlet valve will open allowing the air to be compressed and
re-fill the tank. The idle delay timer will reset for the next cycle.
This sequence of operation will continue until the ON/OFF
switch is turned to the off position.
Your compressor is now ready for use.
NOTE:
All lubricated compressor pumps discharge some
condensed water and oil with the compressed air. Install
appropriate water/oil removal equipment and controls as
necessary for the intended application.
