HORN INSTALLATION (Fig. A)
1. Locate the desired area you wish to mount the dual trumpet air horn. For best results, the front
of the horn should be unobstructed so that the sound can carry straight ahead.
2. Use the horn’s rubber gasket as a template, mark hole locations and drill to sizes as shown in
Fig. A.
3. Secure the horn with the hardware provided. Tighten screws evenly to provide a good
watertight seal..
4. Secure the flexible inlet hose into the base of the horn. Do not remove the Teflon tape on the
threaded end of the hose. The tape is used to help prevent air leaks. CAUTION: Avoid making
any kinks or sharp bends in the flexible hose that will reduce airflow and alter the horn’s
sound.
COMPRESSOR INSTALLATION (Fig. B)
5. Locate an area in the engine compartment that is dry and
safe from the heat of the exhaust manifold. Try to mount
compressor as far to the front of vehicle as possible to
provide a optimum airflow around compressor.
IMPORTANT! Do not mount on a plastic fender well or on
flexible material.
6. Using the compressors mounting as a template, mark hole
locations and drill to size. 15/64’’. Secure the compressor
to the mounting surface with the hardware provided.
TANK INSTALLATION (Fig. C)
7. Locate a convenient area in the vehicle to mount the air storage tank. IMPORTANT! When
selecting a mounting location for the tank, make sure that the compressor metal braided hose
is close enough to connect to the tanks brass female fitting.
8. Use the tanks mounting bracket as a template, mark the hole locations and drill 15/64” holes.
Secure tank with hardware provided using the rubber gasket to prevent vibration noise.
HOSE INSTALLATION (Fig. D)
9. Connect the metal braided hose from
the compressor to the tanks female
brass fitting.
10. Using the 1/4” plastic high pressure hose provided, cut to size to connect
the horn’s flexible inlet hose to the electric solenoid mounted on the air
tank.
11. Unscrew the brass-fitting nut from the flexible inlet hose. Place the brass-
fitting nut onto the hose. Push the hose onto the male fitting of the flexible
hose and tighten the brass nut. CAUTION: Do not over tighten nut.
12. Connect the other end of the hose to the tank’s electric solenoid valve.
Follow the same procedure
as above number 11.
WIRING TANK’S ELECTRIC SOLENOID VALVE (Fig. E)
