COMPRESSOR INSTALLATION: Fig. 3 & 4
7. Install the compressor in a dry interior location.
IMPORTANT: The compressor
should not be mounted further than 30 inches from the trumpet to ensure best sound.
8. To secure the compressor, drill one 3/16” hole. When possible, mount the
compressor vertically (air outlet on top). Install the head of the bolt into the mounting
bracket’s slot on the side of the compressor. Secure the compressor using the lock
washer/nut provided as shown in Fig. 3.
9. Using the plastic tubing provided, cut to
size and connect the compressor to the
horn’s air inlet tube as shown in Fig. 4.
WARNING: Avoid making any kinks
or sharp bends in plastic tubing that
can reduce air flow and alter the horn’s
sound. For best performance and sound,
always keep the plastic tubing as short as
possible.
10. Install the horn relay provided,
locate close to the compressor in a
dry interior location with the terminals
facing downward.
11. Connect relay terminal 87 to the
compressor’s positive (+) terminal. Use
16-gauge wire or heavier.
12. Connect relay terminal 85 to the
horn button switch terminal. (Horn
switch not provided).
13. The horn switch’s other terminal
is connected to negative (-) such as
the (-) battery post battery post or any
clean metal negative surface. Use 18 gauge wire or heavier.
14. Connect relay terminal 30 & 86 to positive (+) 24-volts such as battery, alternator, fuse block or etc., using
16-gauge wire or heavier.
IMPORTANT: Protect the electrical circuit with the fifteen (15)-amp inline fuse
provided. WARNING: The inline fuse provided must be connected directly to the power source.
15. Connect the compressor’s negative (-) terminal to boat’s negative (-) battery post or any clean metal
negative surface. Use not less than 16-gauge wire
.
