AIR TANK & PLUMBING

The tank comes with six 1/4″ NPT port openings to allow installation in many configurations on your vehicle. To ensure safe and trouble-free use of your air tank, we strongly recommend that you install the supplied drain cock and a safety pressure relief valve. (See Figure 1)

Plumbing Diagram:

Tank Fittings:

Install the supplied fittings for the air tank in areas where they are most appropriate for your installation using thread sealant. (Not all installations will be plumbed exactly as shown in schematic.) Make sure that the safety valve is installed in the top most position on the tank, and that the drain cock is installed in the lowest position on the tank if the tank is to be installed in any other position than upright on the tank’s mounting legs. Be sure that all fittings are accessible later in the installation process since you will have to plumb air lines to each fitting as needed to utilize the air tank.

Mounting the Tank:

We have included 6 pieces of rubber bushings in your tank mounting hardware. You have the option of using two layers of rubber bushings on one of your tank legs to slightly tilt tank toward the drain cock port to improve drainage properties. Use the provided longer bolts, and corresponding washers, lock washers and nuts to mount the tank to a suitable chassis or other place on your vehicle.

IMPORTANT :

• Tank is rated for 150 PSI maximum working pressure. (for P/Ns 20011, 20015, 20016, & 20017 only)
• Tank is rated for 200 PSI maximum working pressure. (for P/Ns 20013, 20014, 20019, 20020, 20021, & 20022 only)
• Tank is NOT to be used as a breathing device.
• Use only attachments or tools rated for 150 PSI working pressure or less. (for P/Ns 20011, 20014, 20015, 20016, & 20017 only)
• Use only attachments or tools rated for 200 PSI working pressure or less. (for P/Ns 20013, 20014, 20019, 20020, 20021, & 20022 only

CAUTION! DO NOT PRESSURIZE YOUR TANK UNTIL YOU HAVE INSTALLED ALL NECESSARY PORT FITTINGS AND ACCESSORIES.

• Apply sealant to threads of fittings prior to assembly and tighten each part with a wrench.
• Do not over tighten if your port fittings are made from brass, since brass threads can be stripped.
• Bleed pressure from tank before servicing or adding attachments.

WARNING: FAILURE TO DRAIN TANK AND REMOVE CONDENSATION WILL CAUSE TANK TO RUST PREMATURELY.

• To remove accumulated condensation inside the tank, bleed pressure from tank using the drain cock until pressure is approximately 5-20 PSI.
• Drain tank by opening the drain cock drain valve and close after draining tank.
• If drain cock valve is plugged, release all air pressure from tank, remove drain valve and clean, then reinstall.

IMPORTANT: Please observe air tank’s Date of Manufacture (stamped on tank leg). Replace air tank 2 to 5 years from date air tank was first used, or use the date of manufacture as reference. Adhering to air tank draining guidelines will prolong the life of your air tank.

PLEASE NOTE: RUSTED TANKS CAN FAIL CAUSING EXPLOSIONS OR FATAL INJURIES.
Discard tank immediately if tank is rusted.

SAFETY VALVE: When using a safety pressure relief valve, point the safety pressure relief valve away from your body when releasing air. Use the pull ring on the safety relief valve to vent pressure from the tank before servicing.

DUAL AIR COMPRESSOR INSTALLATION (CONT’D)

Guidelines for Selecting Mounting Location:

The selection of proper mounting location for your air compressor will help ensure a long and trouble free compressor service life. Please pay close attention to the following:

• Select a FLAT, UPRIGHT, & SECURE LOCATION where the compressor can be mounted.
• To maximize air compressor performance, locate compressor as CLOSE TO THE BATTERY as possible so that length of positive lead wire required is at a minimum.
• Choose mounting location that is as cool as possible and away from heat sources.
• This compressor is moisture & dust resistant, but NOT WATERPROOF or DUSTPROOF. Do not mount compressor in locations where the unit is likely to come in contact with water or excessive dirt.
• For compressor with remote filter mounting, select compressor’s mounting location where air line can be routed from compressor air inlet to remote inlet air filter. Make sure that the remote inlet air filter is located in a dry location, away from water.
• You will also want to select a compressor mounting location where the leader hose bracket can be mounted to secure the leader hose.
• If it is necessary to mount the air compressors further from the battery, such as inside your vehicle or in the bed of your pickup, use a minimum 8 AWG positive lead wire for remote installation for each compressor.
• Do not mount compressor near areas where flammable liquids are stored.
• Use thread sealant for proper fitting installation. Thread tape is not recommended. Properly sealed, recommended torque for 1/4″ and 3/8″ is 12~15 ft. lbs.

Compressor Wiring: (See Figure 3 on back of manual)

1. Disconnect ground cable from vehicle’s battery.
2. Temporarily position the air compressor in the location where it will be mounted.
3. Route ground wire to the negative post of the battery or to an appropriate grounding point and cut ground wire to length as needed.
4. Mount the air compressors with the eight sets of 13/64″ (5 mm) bolts, nuts, washers, and locking washers provided. Use of thread locker is recommended.
5. NOTE: For Remote Inlet Air Filter Installation, refer to Remote Inlet Air Filter Installation Instructions included in the Remote Inlet Air Filter Pack.
6. This air compressor comes with a heavy duty heat resistant stainless steel braided leader hose with 1/4″ NPT fittings, except Part#20021 and 20022 which come with 3/8″ NPT fittings.
7. IMPORTANT: Please note; the leader hose that came with your compressor has a built-in inline check valve pre-installed. Do not remove inline check valve from leader hose.
8. Select a proper location to mount leader hoses with hose brackets provided. Avoid locations where leader hose may become tangled with wires and other hoses.
9. To mount hose bracket, drill holes with 3/16″ drill bit and push self–anchoring hose bracket pin into hole. Route leader hose through hose bracket and secure hose by pressing bracket clamp into locked position.
10. To remove hose from the hose bracket, simply press down on the hose clamp release tab to release bracket clamp.
11. Follow wiring diagram on the back of manual (Fig. 3)
12. Make sure that your compressor setup is properly fused. (Fuse not included). Dual 280C compressors pull approximately 33 maximum-Amps of power. Dual 380C, Dual 450C, & Dual 480C compressors pull approximately 44 maximum-Amps of power. Dual 400C compressors pull approximately 60 maximum-Amps of power.Dual 444C compressors pull approximately 40 maximum-Amps of power.
13. Always locate fuse as close as possible to power source.
14. Before connecting to power source, check to make sure that all connections are made properly.
15. Connect and test compressor system by running the compressor for a short time to build up pressure in your air tank.
16. Once air pressure reaches preset cut out pressure of your pressure switch, the compressor will shut off. Inspect all air line connections for leaks with soap and water solution. If a leak is detected, the air line may not be cut squarely or pushed all the way in. Tighten connections if needed.

OPERATING INSTRUCTIONS

IMPORTANT : The compressors have a maximum working pressure of 150 PSI (P/Ns 20011, 20015, 20016, & 20017) or 200 PSI (P/Ns 20013, 20014, 20019, 20020, 20021, & 20022 only). Always operate the compressor at or below the MAXIMUM PRESSURE RATING of the compressor. Operation exceeding maximum pressure ratings and or duty cycle will result in damage to air compressor.

1. Your air compressor is equipped with an AUTOMATIC THERMAL OVERLOAD PROTECTOR. This feature will protect the air compressor from overheating and causing permanent damage to your air compressor. The thermal overload protector will automatically cut off power to your air compressor should the internal operating temperature of the air compressor rise above safe levels during excessive use.
2. Should your air compressor automatically shut off during use, turn power to the system off. The automatic thermal overload protector will automatically reset when internal temperature of the air compressor drops below safe levels. After allowing air compressor to cool off, you can safely resume use of the air compressor by turning on the system.
3. To prevent discharge of your battery and to provide peak performance, it is recommended that you keep the engine running while the air compressor is in use.
4. ONLY OPERATE THE AIR COMPRESSOR IN WELL-VENTILATED AREAS.

Dual Compressor Maintenance & Repairs:

1. Periodically check all electrical and fitting connections. Clean and tighten as needed.
2. Periodically check all mounting screws. Tighten as needed.
3. Replace air filter element periodically. Replacement frequency depends on operating frequency and operating environment. For frequent use in dusty environment, you should replace air filter element more often.
4. Regularly clean dust and dirt from compressor.
5. Your air compressor is equipped with permanently lubricated, maintenance-free motor. Never lubricate compressor.
6. Repairs should be performed by Manufacturer or Manufacturer’s Authorized Service Agencies only.

CAUTION: Never touch the air compressor or fittings connected to the air compressor with bare hands during or immediately after use. Leader hose and fittings will become very HOT during and after use.

Dual Compressor Installation Tips:

1. Always use the remote intake filter option when possible. This will extend the service life of your compressor.
2. If noise reduction from vibration is desired, using the remote mount option for the inlet filter can reduce operation noise by up to 25%.
3. Always mount the compressor at a point higher than the inlet port of the tank. This will keep moisture from being able to seep back to the compressor.
4. When mounting the compressor, use a paint pen on the rubber isolators and cover the side to go against the chassis or mounting location. Then, simply stamp the compressor against the chassis to make an imprint of exactly where to drill the mounting holes for the compressor.

PRESSURE SWITCH INSTALLATION

Your VIAIR® Onboard Air System comes complete with a heavy duty sealed pressure switch that
will turn on the compressor at 110 PSI, and off at 145 PSI (P/Ns 20011, 20015, 20016, & 20017) or
165 PSI on, and 200 PSI off (P/Ns 20013, 20014, 20019, 20020, 20021, & 20022 only). The pressure
switch has a 1/8″ NPT (P/Ns 20013, 20014, 20019, 20020, 20021, & 20022 only) or 1/4″ NPT (P/Ns
20011, 20015, 20016, & 20017) inlet and pre-applied thread sealant.

Pressure Switch and Relay Installation Tips:

1. Both terminals of the pressure switch are positive (+) leads. (The use of a relay is always recommended).
2. Never use a pressure switch that is rated beyond your compressor’s rated Maximum Working Pressure.
3. Replace the Pressure Switch with P/N 90221 (for Dual 380C, Dual 444C, and Dual 480C), or with P/N 90227 (for Dual 280C, 400C, and Dual 450C) if the pressure switch becomes faulty or fails in the future.
4. See Fig. 3 for relay and pressure switch installation tips.

DASH PANEL GAUGE INSTALLATION

Your VIAIR® Onboard Air System comes complete with a Dash Panel Gauge to monitor the pressure of your VIAIR® air tank. Additionally, the Dash Panel Gauge has an ON/OFF switch preinstalled that will allow you to turn the system off by cutting power to the pressure switch that you have already installed. We recommend that you install a master ON/OFF switch to allow the system to be turned off any time you anticipate leaving the vehicle parked for any length of time, and to avoid draining the vehicle’s battery unnecessarily due to a slow air leak in your system. (See Figure 3 on back of manual)

IMPORTANT: Each Dash Panel Gauge has been tested and calibrated. The air inlet on this gauge has a factory installed compression fitting. DO NOT attempt to tighten or loosen the body of this compression fitting. Any adjustments will cause the gauge to malfunction and void warranty. The Dash Panel Gauge included in this kit is rated for 150 PSI (PN 20011, 20015, 20016, & 20017) or 200 PSI (PN 20013, 20014, 20019, 20020, 20021, & 20022 only). Always operate the gauge at or below the MAXIMUM PRESSURE RATING of the gauge.

1. Select Mounting Location for Dash Panel Gauge:
   Select a mounting location with a rigid mounting surface such as the bottom edge of the dashboard. Use the gauge mounting panel as a template; mark off two mounting points to be drilled. Carefully drill two 13/64″ diameter holes as marked. Do not mount Dash Panel Gauge at this time.

2. Air Line Connection to Dash Panel Gauge:
   Remove only the collar of the compression fitting from the back of the Dash Panel Gauge. Do not loosen or tighten the body of the compression fitting, which is permanently affixed to the air inlet of the gauge. Insert air line tubing through this collar, and then push air line tubing onto the barb of the compression fitting until the air line completely covers the barb. Tighten collar onto the body of the compression fitting with a wrench.

3. • When cutting air line tubing, always cut as squarely as possible. Use a hose cutter or razor blade.
   • When routing air line tubing, always remember to avoid sharp edges, heat sources and tight bends.
   • Air line must be routed at least 12 inches from exhaust systems & other heat sources.) Routing Air Line to Tank:
     Route the air line tubing on the Dash Panel Gauge to the tank. Do not cut air line yet, in some cases a hole may need to be drilled to enable the air line to pass through panels to the tank location. Make sure that the air line tubing is protected from any sharp edges of the drilled hole using grommet strip supplied. Connect to the tank using the 1/4″ compression fitting supplied.
     Installation Tips:
     IMPORTANT – Drilling through firewall:

Always be sure of what is on the other side of the firewall before drilling. Take care not to damage your vehicle’s electronic systems or components.

4. Wiring the ON/OFF Switch: Attach one of the two remaining female terminal connectors to the wire that was routed from the pressure switch. There are two male spade connectors on the back of the ON/OFF switch. Connect this female terminal connector to one of the male spade connector on the ON/OFF switch. Next, attach appropriate size ring terminal provided in the kit to the end of the wire with the Inline Fuse. (The ring terminal should be about 12″ from the inline fuse.) This wire is referred to as the power wire. Temporarily position the ring terminal at the power source and route power wire to the dash panel gauge, measure and cut to appropriate length. (If additional wire is necessary, use 16 AWG wire.) Attach the remaining female terminal connector to end of power wire, and connect to male spade connector on the ON/OFF switch. (Note: Do not connect gauge to power source at this time.)

5. Wiring the Dash Panel Gauge for Illumination: There are two wires, one red and one black connected to the light bulb of the gauge. Connect the red wire to a suitable fused dash panel circuit. Use the quick splice connector included in the kit for wire connections. The black wire is to be connected to a suitable ground source.

6. Mounting the Dash Panel Gauge: With all electrical and air line tubing routed and connected properly, mount the dash panel gauge using the two 13/64″ nuts, bolts, and washers included with the Dash Panel Gauge. Make sure that no electrical wires or air line can be contacted by vehicle pedal operation, or by use of any safety equipment. Use provided zip ties to secure air line and electrical wiring.

7. Connect to Power Source: Before connecting the power wire to a power source, check to make sure that the ON/OFF switch on the dash panel gauge is in the OFF position. Connect the ring terminal of the power wire to power source. (This is the wire described in Step 4, which is connected to the ON/OFF switch of the dash panel gauge.)

8. Testing Your Onboard Air System: Your Onboard Air System installation is now complete. Run the compressor to build pressure in the air tank. When air pressure reaches the pressure switch cut out pressure, the compressor will shut off. Inspect all air line connections for leaks with soap and water solution and spray with a spray  bottle onto connections to check for leaks. If leaks are detected, air line may not be cut squarely or pushed all the way in. Fix connections as needed. Periodically check your system’s fitting in this manner should your compressor turn on more often than normal without frequent air use.

INLINE PRESSURE REGULATOR INSTALLATION

Your Onboard Air System comes complete with an adjustable inline air pressure regulator that may be used to regulate the pressure out of your air tank down to desired pressure. This is especially useful for installations that will supply air to a locking differential, or may be used to operate air tools. Never attempt to use the regulator to adjust any tank pressure over Maximum Pressure Rating of the compressor and other components.

1. Mounting the Inline Pressure Regulator:
   Select a mounting location with a rigid mounting surface such as the bottom edge of a chassis. Use the inline pressure regulator mounting bracket as a template to mark the two mounting points to be drilled. Carefully drill the two holes as marked, and mount the Pressure Regulator at this time.

2. Air Line Connections to Inline Pressure Regulator:
   Use a 1/4″ NPT compression fitting on the “IN” side of the regulator receiving air from the air tank. On the “OUT” side of the regulator, you may install a 1/4″ NPT quick connect coupler, or use another 1/4″ NPT compression fitting to route the air line to the source of the item that pressure is being regulated to. If you are plumbing to air locking differentials, we have included two 1/8″ BSP Female to 1/4″ NPT Male Adapters for this use. You may require a T-fitting (included in the package), depending on your application.

3. Adjusting pressure:
   The pressure regulator knob locks when pushed towards the unit. To adjust pressure, simply pull knob away from the regulator body and adjust as needed. Always lock the adjustment knob in place before using pressure-adjusted air supply to keep pressure regulated at a fixed pressure. (S ee Figure 2)
   
   

TIRE INFLATION GUN OPERATING INSTRUCTIONS

Your Onboard Air System also comes with a Tire Inflation Gun for airing up tires and adding compressed air to any inflatable items with a valve stem.

1. Using the Tire Inflation Gun:
   Using a 1/4″ Quick Connect Coupler, connect the Tire Inflation Gun to an air hose and connect to a tire valve stem or similar inflation collar by securing the folding lever on the Inflation Gun air chuck.

2. Filling Tires and other Inflatable Items :
   Squeeze the Inflation Trigger on the Inflation Gun by pressing it towards the handle of the gun. This will allow stored air from the air tank to flow through the gun and through the chuck into your tire or other inflatable items.

3. Checking Tire Pressure:
   To check tire pressure, release Inflation Trigger on Inflation Gun and allow the needle of the 0-200 PSI gauge to settle. Tire pressure will be able to be read only when the inflation trigger is released.

WARNING:

• Never operate the Inflation Gun at any pressure exceeding 200 PSI.
• Use caution when attaching or removing air chuck from valve stems.
• Always ensure that tire valve stems are tight before inflating tires.
• Be careful to never inflate any tire or other inflatable items past its rated pressure to avoid explosion, possible injury, or death.

Please Note: Not intended for use with regular portable compressors or units meant to be operated with an open ended air chuck. The Tire Inflation Gun is equipped with a closed ended chuck and will hold pressure back, which could cause the hose to burst.
