WARNING
- Check for contaminants in oil. Dirty oil makes for plugged valves and can cause issues with over pressurizing the radiator
- Start tractor and warm oil prior to starting up fan. This should be done anytime the fan circuit is started
- Engage fan hydraulics at low flow rate and low fan RPM and slowly
- Bleed hydraulic lines of air for stable oil
- Check pressures at radiator gauge. If pressure is higher than normal, steps must be taken to reduce return line
- Call Airguard if you have any 1-604-744-0070

STEP| 15. Start up operating procedure.| REV #| 1.0
PART KIT #| Varies
START-UP PROCEDURE
After you have installed the Airguard Blockage Prevention System it’s critical that you start the Aircart fans very slowly. You’re introducing an air pocket that must be moved slowly to the tractor while you prime the hydraulic lines with oil. This process is a good way to make sure your fittings are sealed and secure.
-
Get your oil warmed to 80-100 deg F. If your oil is cold, the viscosity is very high and it will not move through the internal components easily. By warming the oil first, everything will operate as it should.
-
Initiate your fans with 500 Fan RPM at 25% oil flow (or 10% of your max fan speed). If everything looks good, the pressure is just starting to register on the Airguard pressure gauge. If all your fittings are holding their seal, continue to the next step. If your fan is NOT moving, that’s okay. The oil is circulating. Operate this way for 5
NOTE: If there is a pressure spike at this low oil flow rate, there is potential for an air lock. Disconnect the end fitting on the Return Line at the SCV and drain off some oil to release the pressure. Reconnect the end fitting and repeat Step 2. -
Run 1000 Fan RPM at 45% oil flow (or 35% of your max fan speed). Operate for 5
-
Run 2000 Fan RPM at 65% oil flow (or 75% of your max fan speed). Operate for 5
-
Run 3500 Fan RPM at 85% oil flow (or 100% of your max fan speed). Operate for 3-5
-
Take time to ensure that your conveyor or auger is working properly in conjunction with your Airguard kit. Turn your fan RPM down to 50% oil flow and engage the conveyor/auger. If everything is operating as it should, you have successfully installed your Airguard Blockage Prevention System kit.
If there are any questions or concerns about the operations, call your AIRGUARD Sales Representative using contact information found at www.airguardproducts.com/contact or visit us at www.airguardproducts.com/productsupport.
Now you’re ready to operate! Follow the same warm up procedure you do every day and go seed. This is a procedure that we highly recommend at the beginning of each future season, to ensure the continuation of successful operations. It is a critical step in the introduction of new machinery to your farm operation. After the freeze and thaw of seasons we want to eliminate any air pockets or leaks that could slow preparations

PREVENTATIVE MAINTENANCE
- Ensure that the startup procedure on page 16 is performed every morning before seeding begins.
- Take extra precautions when seeding in cold weather.
- It is recommended that a bypass valve is purchased to allow for quicker startup.
TROUBLESHOOTING
| Trouble | Probable Cause | Remedy |
|---|
Fluctuating pressures on pressure gauges and strange noises coming from fan
motor.| High return line pressure| The logic cartridge on the BP System is set
to 750psi. Any value close to or above that will cause fluctuations and issues
with fan speed. Reduce return line pressure to fix this problem.
Faulty quick disconnect couplers| Replace quick disconnect couplers, inspect
ball valve to ensure proper working order
Restriction in return line due to small fitting| Replace fitting with a larger
one
Logic cartridge is contaminated| Clean or replace the logic cartridge as
needed
Fan won’t run| High return line pressure| The logic cartridge on the BP System
is set to 750psi. Any value close to or above that will cause fluctuations and
issues with fan speed. Reduce return line pressure to fix this problem.
Quick couplers are disconnected| Ensure that quick couplers are connected
properly
Logic cartridge is contaminated| Clean or replace the logic cartridge as
needed
Logic cartridge is faulty| Replace the logic cartridge
Hoses are hooked up incorrectly| Consult owner’s manual to see proper
installation of hoses
Cannot get fan speed up to normal levels| Pressure/flow is too low at tractor|
Increase pressure/flow
FREQUENTLY ASKED QUESTIONS
Q: Why can’t I operate my Blockage Prevention System without warming up
my tractor first?
A: Tractor motors and seeding equipment are built to withstand fast
startups; an aluminum radiator is not. On a cold day at 10% oil flow, your
return pressure could be at 500psi on our Blockage Prevention System. If you
were to do a fast startup in cold conditions, you could have a radiator fail.
Pressures could dra- matically spike beyond the capacity of our 2400psi rated
aluminum core.
Q: Will the Blockage Prevention System cause dramatic pressure drops in
my oil flow?
A: While the BPS will cause a slight pressure drop (approximately 400 RPM
or less), the drop in oil flow is negated because of the warm air being
transferred from the oil into the airstream. This allows the internal product
to flow more efficiently. The reason for the slight pressure drop is that the
oil has to pass through the orifices of the radiator, which are smaller than
the hoses used prior to the installation of the Blockage Prevention System.
Q: Does the Blockage Prevention System actually work?
A: We can honestly say that it does. The hotter the oil is in the
hydraulic lines, the more heat the Blockage Prevention System can extract out
of that oil. Since the mechanism is mounted on the face of the fan housing,
the fan is pulling air through the fins of the radiator while the air cart is
pressurizing up to operate. The hot oil, running through the radiator, acts
like a furnace and changes the air temperature on the inside face of the
radiator. That air is then pulled into the air cart stream and is pushed out
towards the openers, where the seed is placed into the furrow. Warmer air
holds more moisture. Humidity will stay in a vapor state when it is drawn in
and will be less likely to turn into a liquid while the air and all the hoses
and internal components are physically warmer. This allows the product to flow
through with less resistanc eand minimizes buildup of dusty fertilizer
internally. Seed and fertilizer will be delivered to the discharge outlets
without problems.
Q: What is the purpose of the new bypass valve?
A: The new bypass valve upgrade kit allows you to heat up your oil before
engaging your Blockage Prevention System. You can also choose whether or not
to use your BPS in the heat of the day.
Q: What pressure should the pressure gauge read on the Blockage
Prevention System?
A: 300-600psi is an acceptable pressure range when operating. The gauge
reads the pressure of the oil going through the radiator, on the return side
of the fan motor.
Q: Do I need to reset the relief valves on the V2 Blockage Prevention
System?
A: No you do not. The valves are preset to 750psi and 850psi. If they do
get changed or altered, please contact Airguard in order to have them reset
