Wolo 140 Sea Alert - Manual

Your purchase of a Wolo SEA ALERT™ Air Horn will complement your boat, while offering an extra level of
protection. Wolo’s products are manufactured with the finest materials. Before being packaged, each horn
is tested to ensure it meets all of our manufacturing specifications. If you need help installing your new Wolo
horn, our technicians are available to answer your questions, Monday thru Friday, 9 AM to 4 PM EST at
1-888-550-HORN (4676).
Before installation of the horn is attempted, it is important to read these instructions completely. The lives of
people can be dependent on a proper installation of the horn. The person doing the installation must have
knowledge of the proper method for mounting and securing the horn to the exterior of the boat, as well as
knowledge of the boat’s electrical system. Again, read the instructions completely and note any messages
marked
“IMPORTANT” or “WARNING’’. A safe installation will prevent injury or damage to the boat.
WARNING: Installation of the SEA ALERT requires drilling. The installer must carefully inspect both sides of
the selected mounting locations to ensure that there are no wires, fuel lines and or any other components that
could be damaged by drilling.
WARNING: If any wires are routed through drilled holes, always de-burr ensuring that there are no sharp
edges. Install a rubber grommet into all metal holes that wires are being routed through.
MOUNTING TRUMPET: Fig. 1 & 2
IMPORTANT: The horn should be mounted facing forward
whenever possible. The NMMA Certification Program
requires this for boats 39’ or longer.
1. Locate the desired mounting location of the trumpet.
For best results, the front of the horn should be
unobstructed so that the sound can carry straight ahead.

TRUMPET, KEEPING THE HOSE LENGTH AS SHORT AS
POSSIBLE. THE COMPRESSOR MUST BE MOUNTED IN
A DRY INTERIOR LOCATION).

and drill to size.
3. Thread the chrome air inlet tube into the base of the horn.
4. Mount and secure the horn as shown in Fig. 1.

gasket to protect against water leaks. Tighten the base
plate front screw and rear nut that threads onto the air
inlet tube evenly to ensure a watertight seal.
5. Position the front trumpet support bracket around the
narrow part of the trumpet.
IMPORTANT: Provided in the
kit is a soft rubber strip that is placed into the ring of the
support bracket to provide a tight fit and prevent vibration.
Push the bracket forward until it is tight. Use the bracket as
a template, mark hole locations and drill to size. See Fig 2.
