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 airline and wire to install the system before beginning the installation.
• Make sure mounting locations are secure and clear 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; unless a white or
red PTFE paste is already applied.
• Air valves can be mounted in any position but are recommended to be mounted vertically with the pilot housing above
the valve body. Make sure the directional arrow is pointed towards the horns.
• Use the supplied 10 gauge wire or thicker (lower gauge #) wire to power your air compressor.
We recommend installing our kits in a certain configuration. With the 5 gallon tank, you have seven 1/2” ports and one 3 /4”
port. Install the tank in position where one 1/2” port is facing down, then use the 1/2“ to 1/4” reducer bushing fitting for the
drain cock. From there place the gauge, pressure switch and safety blow off valve in three 1/2” ports using the 1/2“ to 1/4”
reducer bushings. For two 1/2” ports, one of them will have the 1/2” to 1/4” female reducer bushing for the compressor (1/2” to
3/8” for the Viair 480c) and the other 1/2” port is for the 1/2” PTC to 1/2” NPT M fitting for the horns.

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 grommet strips (plumber’s strap), sheet metal
or any sort of custom bracket. Note that air line will be running to the center of the horn mainfold.
1. Locate a secure, dry, and safe position for your horns.
2. Install your custom bracket. We recommend welding a piece of sheet metal.
2. Drill holes in your bracket to align with the AirChime manifold.
3. Secure the horn on to the bracket.
