Wolo 845 Road Warrior v.1 - Manual

AIR HORN INSTALLATION
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
size as shown in Fig. A.
3. Secure the horn with hardware provided. Tighten evenly to provide a good
water tight seal. Fig. A.
4. Push the front mounting bracket until it is tight.
5. Follow the same procedure as above steps 2-3 to secure the front mounting
bracket (Fig. B.)
6. Secure the flexible inlet hose into the
base of the horn. Do not remove the
Teflon tape on threaded end of hose.
The tape is used to prevent air leaks.
7. Install the tank and the trumpets back
onto the horn’s base. Only hand
tightening is required.
COMPRESSOR INSTALLATION
8. Install the compressor in a dry location.
IMPORTANT: Compressor must be mounted not
further than 8 to 10 inches from the trumpet for
proper sound.
9. To secure the compressor drill one 5/16” hole.
When possible, mount the compressor (air outlet
on top). Install the head of the bolt into the slot on
the side of the compressor. Secure the
compressor to the vehicle using the lock
washer/nut provided as shown in Fig. C.
10. Using the plastic tubing provided, connect the compressor to the horn’s flexible inlet
hose as shown in Fig. D.
Caution: Avoid making any kinks or sharp bends in plastic tubing that will reduce air flow
and alter the horn’s sound.
WIRING
11. Electrical Connection – Using Vehicle Factory Wiring
IMPORTANT: You are not required to use the relay supplied with
the kit because the vehicle factory system already has a relay.
A. For two (2) wire systems: If vehicle’s factory horn has two (2)
terminals, simply transfer wires to the compressor’s terminals.
IMPORTANT: when testing the horn if compressor turns on but
the horn does not sound, reverse the wires connected to the
compressor.
10. B. For one (1) wire systems: If vehicle’s factory horn has one (1)
terminal, simply transfer the wire to the compressor’s positive (+)
terminal.
10. C. Use16-gauge wire or heavier, the compressor’s negative
terminal is connected to any metal body bolt. A ground
connection should be free of rust and paint.
