II. 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.
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.
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 Teon 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 two 1/2” NPT ports and four 1/4” NPT ports. Your train horn kit should use one of the
1/2” ports and the other 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 Teon 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 cutting equal lengths of 5/16” tubing to run from each horn to the banjo fitting.
4. Install your banjo fitting into the outlet port of your 1/2” air valve. 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. Plumb each horn to the banjo fitting, making sure that the lines are inserted firmly into their sockets. You do not use Teon tape
or pipe sealant with the PVC fittings.
6. Finally connect your air valves inlet port to your air tank using 1/2” air line using the 1/2” M NPT to 1/2” PTC fittings. Make sure
to use a side or top port on your tank so that condensation will not drain in to your air valve.
DRAIN COCK TO TANK:
1. Install the drain cock into the bottom 1/4” port on the bottom of the tank. If the drain cock already has sealant on its threads it
is unnecessary to use Teon tape on the threads.
PRESSURE SWITCH IN TO TANK:
[Air Tank] » [1/4” NPT Port] » [Pressure Switch unit]
1. Install the pressure switch unit into an available port on the air tank using Teon tape or pipe sealant on the threading. 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.
INSTALLING YOUR TRAIN HORN KIT
(cont.)
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.
