AW339- HOT TUB OEM INSTALL
The AW339 mounting bracket is the component used to attach the
transducer to the hot tub or spa. The mounting bracket and related hardware
come in the transducer package.
The mounting bracket assembly includes the mounting bracket, a threaded
stud, and two jam nuts (see diagram below). The mounting bracket is
secured to the underside of the hot tub. The threaded stud attaches the
transducer to the mounting bracket. The jam nuts secure the threaded stud
to the mounting bracket and transducer.

Mounting Bracket
When prototype testing the transducer with your hot tub, the mounting
bracket can be applied to the hot tub with epoxy. During this type of
application, do not allow the epoxy to expand into the hole where the
threaded stud is placed or you will not be able to insert the stud.
There are several factors to consider when selecting the mounting location
for the mounting bracket and transducer:
1.
You need to insure the area allows for adequate clearance for the
transducer. The transducer should only touch the tub by way of the
mounting bracket. If the transducer comes in contact with other parts of
the hot tub it may affect the sound quality.
2.
The location should allow for as much air space around the transducer
as possible. This will allow heat to escape from the transducer.

3.
The location should be accessible. This will prove invaluable should the
transducer require service.
4.
You may want to locate the transducer close to the location of the hot
tub's amplifier/sound unit to avoid additional wiring.
5.
For larger tubs, you may want to consider mounting two transducers for
added performance.
TRANSDUCER LOCATION
CROSS-SECTION OF TUB
Once prototype testing is complete and a final location is determined,
the mounting bracket should be permanently fused with the tub during
production. This process involves covering the bracket with fiberglass.
Again, insure the threaded hole is protected during this process so no
material obstructs the threads/opening. The factory install is now complete.
Once the hot tub is installed by the dealer, the dealer can then install the
transducer. DO NOT SHIP WITH THE TRANSDUCERS ATTACHED. This
installation is done by placing the transducer's brass mounting nut onto
the threaded stud. Insuring not to crossthread the brass nut, gently turn
the transducer 5 to 6 complete revolutions. If you feel resistance, stop
immediately. CAUTION: DO NOT OVERTIGHTEN. Spin the jam nut on the
stud down to the brass nut and, using two wrenches (one on the jam nut
and one on the brass nut), tighten the jam nut against the brass nut.
CAUTION: DO NOT TIGHTEN THE JAM NUT TO THE BRASS NUT
BY TURNING THE TRANSDUCER. THIS WILL RESULT IN SEVERE
DAMAGE TO THE TRANSDUCER AND WILL VOID THE WARRANTY.
You may now connect the wires to your amplifier (must be a 4 ohm stable
amp delivering 125-150 watts @ 4 ohms/speaker). Your install is complete.
