Installing Your Train Horn Kit
Planning Your Installation
This is the most important step in your installation.
•
Plan out the location of each component before starting your installation.
•
Make sure you have enough air line and wire to install the system before beginning the installation.
•
Make sure mounting locations are secure and void of debris.
•
Try to keep the supply wire to the compressor as short as possible. Wires lose voltage over distance
therefore shorter wires will result in better performance.
•
Mount your air compressor in a location that is as cool as possible and away from heat sources. This will
make your compressor run cooler and last longer.
•
Your air compressor must be mounted upright or horizontally but never upside down to allow the
compressor to cool properly. To increase performance make sure the compressor is mounted upright.
•
Your air compressor should be mounted above the tank. Failure to mount the unit in this position will
allow any condensation buildup to drain back in to the compressor and foul its components.
•
Teflon tape or a locking compound should be used on every fitting in your air system to prevent air leaks.
•
Air valves can be mounted in every direction but are recommended to be mounted vertically with the pilot
housing above the valve body.
•
Use the supplied 12 gauge wire or thicker (lower gauge #) wire to power your air compressor.

I. Installing Your Nathan AirChime Train Horn
Locate an area for your horns that is dry and free from debris. The horns can be mounted in any direction and
still be heard from all around. The horns should not be mounted where they will be completely submerged or will
receive any kind of impact. Horns may be mounted directly to your vehicle, on a medium such as sheet metal or
any sort of custom bracket. Note that air line will be running to the center of the horn manifold.
1.
Location a secure, dry, safe position for your horns.
2.
Install your custom bracket. We recommend welding a piece of sheet metal.
3.
Drill holes in your bracket to align with the AirChime manifold.
4.
Secure the horn on to the bracket.
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 six feet away from the
air compressor.
