INSTALLING YOUR TRAIN HORN KIT
III. INSTALLING YOUR AIR COMPRESSOR PUMP
Locate a at 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. Make sure to cut equal lengths of air line to connect
each horn to the manifold or the horns may sound at different times. 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. The air valve
should connect to the center fitting of the 4-point banjo fitting. 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.
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 ow and the damage is irreversible.
IMPORTANT: The air valve is directional and must be properly installed. There is an arrow on the brass body of the valve
that shows the airow direction, the arrow must point towards the horn. Improper installation will cause the
valve to malfunction and create a constant air leak to the horns.
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" to 4x 5/16"
NPT M Banjo Fitting] » [5/16" Air Line] » [5/16in P2P to 1/8in NPT F Elbow] » [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 at and the cut
is completely perpendicular to the tubing length.
7. Finally install the air line carefully between the horns and the air valve making sure not to damge the PTC fittings.
