It is important to determine the maximum air pressure for any tool or attachment before using it.
Air sprayer or nozzle should always be pointed away from any part of the body.
The compressor has Thermal Overload Protection, if this protection activates, cut off the source of power and let
the unit cool down for about 30 minutes. This will reset the system and allow you to safely resume use of the air
compressor.
Make sure your battery ground is detached before you begin.
Set the horn up for use only in areas with adequate ventilation.
Employ equipment for eye protection during drilling operations.
Ensure that your air system has no pressure before you begin.
PLANNING YOUR INSTALLATION
Before beginning
the installation, determine each component’s spot.
Confirm you have the proper length of airline and wire.
Power wire to compressor should be kept short.
To power up the air compressor, make sure you use a 12-gauge wire or thicker.

MOUNTING
Identify a suitable area to mount each trumpet, preferably an unobstructed sheet-metal surface like the frame
or body of the vehicle so as to provide a firm platform which will help protect the trumpets from damage due
to excessive shaking. Do not attach trumpets to any plastic or other flexible material.
Using the back bracket as a guide estimate and mark the positions for the holes, then perforate to size using
a drill.
Use the provided mounting hardware to fasten the trumpets.
AIR LINE INSTALLATION
Follow the diagram below to connect the solenoid, fittings and hoses to the air system and trumpets.
Make sure to use the included thread sealant in all threads.
WARNING
: Do not overtighten.
IMPORTANT
: A small arrow on the valve's body will show the direction of the airflow, this direction must be
from the air system to the trumpets.
