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

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.

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.

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.
