The best way to ensure an optimal performance is that:
• The compressor is mounted straight-up with sufficient space for cooling.
• The compressor needs exactly 24VDC. Keep the wiring between the compressor and the
power supply as short as possible.
• The air horn is mounted on a downward slope (1-2°) with no obstacles in front of the horn.
• The distance between the compressor and the air horn must be as short as possible without
any sharp curves. (max. 10 metre)
If the horn is loosened from the diaphragm casing, its recommended that the nipple of the horn is
taped be fore tightened, see figure.

While adjusting the air horn it’s recommended that you wear ear protection,
to prevent damage to your ears.
Although the air horn is tested and adjusted before delivering, it is possible that its setting is
changed. Altering its setting is possible by loosen or tighten the lid of the diaphragm casing. Be
aware that if you tighten the lid to far on the diaphragm casing, the diaphragm plate in the lid will
be damaged.

8. ADJUSTING THE AIR HORN
9. MAINTENANCE
The Single-tone set is almost maintenance free. Make sure the air horn is clean and give the com-
pressor two drops of hydraulic oil monthly. Don't paint the air horn, because this can reduce the
sound pressure level and alter its frequency.
