Important Safety Instructions

CAUTION: To prevent the risk of electrical shock or electrocution:

• Do not disassemble any electrical components of this horn kit (air compressor, air valve, pressure switch).
Do not attempt repai rs or mod ifications of any component. Please refer to qualified service agencies for
all service an d r ep a irs.

• Do not operate any component where it can fall or be submerged into water or any kind of liquid.

• Do not reach for any comp onent that has fallen o r b een submerged into water or any kind of liquid.

• Use the included components with 12 volt DC systems only.

• Do not leave the air system unattended during use.

WARNING: To prevent injury:

• Never allow children to operate the compressor or air horn. Use close supervision when operating this
equipment near children.

• The air compressor will become very HOT during and immediately after operation. Do not touch any p a rt
of this compressor with your bare hands during or immediately after use.

• Do not use this product near open flames or explosive materials or where aerosol products are being used.

• Do not operate this product where oxygen is being administered.

• Do not pump anything othe r than atmospheric air.

• Never use this product while sleepy or drowsy.

• Do not use any tools or attachments with the supplied air source unit without first determining maximum

air pressure for that tool or attachment.

• Never point any air nozzle or air sprayer toward another person or any part of your body.

• The included air compressor is equipped with an automatic reset thermal protector and can automatically

restart after the thermal protector resets. Always cut off power source when thermal protector becomes
activated.

• Use only in well ventilated areas.

• Do not sound the air horn( s) in close proximity to another person’s or your own ear(s).

• Do not fill the included air tank above 150 PSI. Doing so may result in death or serious injury.

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 loca t io n s are secure and vo id 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 compresso r should be mounted abo ve 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 g a uge #) wire to power your air compressor.

Recommended Tools

• 3/8” Long Socket (Horn Front Mount)

• 1/2” Long Socket (Horn Rear Mount)

• 1/2” Wrench (Std. Compression Fittings)

• 9/16” Wrench (1/4 NPT Fittings)

• 8mm Wrench or Socket (Air Compressor Mounting)

• 16mm Wrench (Metric 1/4 NPT Fittings)

• Drill (With 3/16” and 7/16” Bits)

• Wire Cutter/Stripper

• Tubing Cutter/Razor

• Eye Protection

I. Installing Your HornBlasters Train Horns

Locate an area for your horns that is dry and free from debris. The horns can be mounted in any directio n 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 each horns
rear mount.

1. Location a secure, dry, safe position for your horns.

2. Drill a 3/16” hole for the front mount of eac h horn and a 7/16” hole for each rear mount.

3. Secure the horn using the supplied mounting hardware.

II. Installing Your Air Compressor Pump

Locate a flat and secure installation area that will rem ain free of dust, dirt a nd 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. Install the compressor’s air filter assembly:

a. 280C: Remove the orange plug in the compressor’s inlet and mount the included air filter in its

place.

b. 400C: 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.
