Product Usage Instructions
Step 1: Remove Existing Fan Screen
Remove the existing fan screen (Item 1) from the fan housing
(Item 2).
Step 2: Install Mounting Bracket
Install the supplied mounting bracket (Item 1) to the fan
housing (Item 2) using existing bolts and nuts (Item 3). Angle
mount the bracket in a position that ensures the supplied hydraulic
hoses reach the fan motor. Additional holes in the bracket face
(Item 4) are for easy access with an impact driver.
Step 3: Bolt Oil Cooler/Radiator Assembly
Bolt the Oil Cooler/Radiator Assembly (Item 1) to the BP System
Bracket (Item 2) using supplied 10mm x 25mm Bolts (Item 3) and 10mm
lock nuts (Item 4). If only installing the snorkel kit without the
radiator, then install plastic plugs (Item 5) onto the BP System
Bracket (Item 2).
Step 4: Mount Brackets
Remove the packaging materials prior to the assembly of these
brackets. Mount the BP System Main Bracket with Oil Cooler (Item 1)
or Main Bracket with Plugs (Item 2) to the Fan bracket (Item 3)
using supplied pivot pins (Item 4). Secure in place with 3.5mm
cotter pins (Item 5).
Step 5: Attach Mesh Screen or Snorkel Housing
Attach the Mesh Screen (Item 1) or Snorkel Housing (Item 2) to
the front of BPS using latches (Item 3).
Frequently Asked Questions (FAQ)
Q: Can I skip certain steps if I am only installing the snorkel
kit?
A: Yes, you can skip certain steps if you are only installing

DO NOT ADJUST VALVES
WARNING:
· Check for contaminants in oil. Dirty oil makes for plugged valves and can
cause issues with over pressurizing the radiator core.
· Start tractor and warm oil prior to starting up fan. This should be done
anytime the fan circuit is started up.
· Engage fan hydraulics at low flow rate and low fan RPM and slowly increase.
· Bleed hydraulic lines of air for stable oil flow.
· Check pressures at radiator gauge. If pressure is higher than normal, steps
must be taken to reduce return line pressure.
· Call Airguard if you have any questions. 1-604-744-0070

RELEASE DATE REV # PART KIT #
2023-03-01 1.0 Varies
—– WARNING —–
START UP PROCEDURE:
Start up procedure is critical to reduce pressure spikes.
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.
1. 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.
2. 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 minutes.
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.
3. Run 1000 Fan RPM at 45% oil flow (or 35% of your max fan speed). Operate for 5 seconds.
4. Run 2000 Fan RPM at 65% oil flow (or 75% of your max fan speed). Operate for 5 seconds.
5. Run 3500 Fan RPM at 85% oil flow (or 100% of your max fan speed). Operate for 3-5 minutes.
6. 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.

Title STEP
Airguard Blockage Prevention System Upgrade Instructions Troubleshooting and preventative maintenance.
PREVENTATIVE MAINTENANCE 1. Ensure that the startup procedure on page 16 is
performed
every morning before seeding begins. 2. Take extra precautions when seeding in
cold weather. 3. It is recommended that a bypass valve is purchased to allow
for quicker startup.
TROUBLESHOOTING
Trouble
Probable Cause
Fluctuating pressures on pressure High return line pressure gauges and strange noises coming from fan motor.
Faulty quick disconnect couplers
Fan won’t run
Restriction in return line due to small fitting Logic cartridge is contaminated High return line pressure
Quick couplers are disconnected Logic cartridge is contaminated Logic cartridge is faulty Hoses are hooked up incorrectly
Cannot get fan speed up to normal levels
Pressure/flow is too low at tractor

Remedy
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. Replace quick disconnect couplers, inspect
ball valve to ensure proper working order Replace fitting with a larger one
Clean or replace the logic cartridge as needed 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. Ensure that quick couplers are connected properly

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 dramatically 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.
