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 your lengths with at
least an extra inch per line just to be safe. Unlike compression fittings, the push to pull connectors can be used multiple times.
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. The air valve may be mounted in any direction but it is preferred
that it is mounted vertically. Your tank has seven 1/2” NPT ports and one 3/4” NPT port.
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] » [1/2” NPT M to 1/2” PTC Fitting] » [Air Valve] » [1/2” NPT M
to 1/2” PTC Fitting] » [1/2” Air Line] » [1/2” NPT M to 1/2” PTC Fitting] » [Rear Horn Mount]
1. Plan out the fittings placement 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. Start by installing the 1/2“ PTC to the tank.
4. Install the valve in a safe location, preferably closer to the horns. If the valve has a directional arrow on its body, the
arrow starts with the inlet and points out the outlet; the arrow should point towards your horns.
5. Next install PTC fittings on both open sides of the valve and on the bottom of the horn manifold. Make sure that the lines
are inserted firmly into their sockets. You do not use Teflon tape or pipe sealant with the PVC fittings.
6. Now run the air line from your horn manifold to the air tank and cut the length required. Make sure the cut end is flat and
the cut is completely perpendicular to the tubing length.
6. Finally install the air line carefully between the horns and the air valve making sure not to damge the PTC fittings.
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.
