II. Installing Your Air Compressor Pump
Locate a flat and secure installation area that will remain free of dust, dirt, and debris (your compressors performance is
directly affected by air quality). Try to keep the distance of the unit from the battery to a minimum to keep your compressor
running at maximum performance.
1. Disconnect the ground cable from the vehicle’s battery.
2. Position the unit in the desired location and secure it using the supplied mounting hardware (8mm).
3. Remove the orange plug in the compressor’s inlet and install the remotely mountable air intake assembly. Using the
included 3/8” OD air line and fittings you may relocate the air filter up to 6 feet away from the air compressor.
4. Only hand tighten the check valve.

IV. Installing Your Air Tubing & Air Valve
Before cutting any air tubing make sure to double check your measurements. We recommend cutting lengths with at least an
extra inch per line just to be safe. Compression fittings use ferrules (olives) that should only be used once. When threading any
fittings make sure to use Teflon tape or lock-tight to prevent air leaks. Some fittings may already have pipe sealant applied on
their threads for your convenience. Your tank has seven 1/2” NPT ports and one 3/4” NPT port. Your train horn kit should use
one of the 1/2” ports and the others may be reduced to 1/4” reducer bushing if necessary.
Air Compressor to Tank:
[Air Compressor] » [1/4” Leader Hose] » [1/2“ to 1/4” NPT F Reducer] » [Air Tank]
1. Carefully connect the air compressor leader hose to the 1/2” to 1/4” NPT F Reducer bushing that is located on either end of
the tank using Teflon tape or paste on the treading. When installing the leader hose DO NOT move the inline check valve
located just above the swivel fitting.
a. If installing a Viair 480c you will use a 1/2“ to 3/8” NPT F Reducer.
2. Locate a secure location to mount the leader hose using the bracket provided. Avoid locations where the leader hose may
become tangled with wires and other hoses.
a. When mounting the bracket, drill a hole with a 3/16” drill bit and put the self-anchoring hose bracket into the hole.
Route the leader hose through the hose bracket and secure by pressing the bracket clamp into the locker position.
Air Horns to Tank:
[Air Tank] » [1/2” NPT M to 1/2” PTC Fitting] » [1/2” Air Line] » [Air Valve] » [Rear Horn Mount]
1. Plan out the fittings placement out before you begin and make sure you understand the correct order.
2. Make sure that your tank is empty of air and that the compressor is not running during installation.
3. Install the airline carefully using two wrenches for each compression fitting. Use one wrench to hold the body
stationary and another to tighten the compression nut.
4. Measure and plumb one length of 1/2” tubing from the tank compression fitting to the air valve located on the horn.
5. Next connect your air valve’s inlet port to your air source unit using 1/2” air line and 1/2” to 1/2” PTC fitting.
III. Installing Your Air Tank
Locate a secure area close to your air compressor to mount your air tank. The leader hose of the compressor should be able to
reach an available port on the air tank with some slack.
1. Position the tank in its desired location and secure it using standard mounting hardware.
IMPORTANT:
Do not rotate or remove the inline check valve in the compressor’s leader hose. Doing so will damage its
seals and will result in damage to your air compressor and voiding of your warranty.
IMPORTANT:
Do not make any kinks in your air line. Doing so will disrupt air flow and the damage is irreversible.
Drain Cock to Tank:
1. Install the drain cock into the 1/2” port on the bottom of the tank using the 1/2” to 1/4” NPT F bushing. If the drain cock
already has sealant on its threads it is unnecessary to use Teflon tape on the threads.
Pressure Switch in to Tank:
[Air Tank] » [1/2” NPT Port] » {1/2“ to 1/4” Reducer Bushing] » [Pressure Switch unit]
1. Install the pressure switch into an available 1/2” port on the air tank using Teflon tape or pipe sealant on the threading of the
1/2” to 1/4” NPT F bushing. Make sure to mount the pressure switch on the side or the top of the tank so that condensation
will not be able to drain in to the pressure switch. Hand tighten only, and don't tighten by twisting the box.
