5.3.2 Connecting Tips, Horns, and Converters
Connecting the Horn to the Converter
To connect the horn to the converter, take the following steps:
Table 5.10 Connecting the horn to the converter
Step Action
1
Clean the contacting surfaces of the converter and horn, and remove any
foreign matter from the threaded stud and threaded hole.
2
For 20kHz and 30kHz assemblies, insert a single Mylar washer between the
mating surfaces.
For 40kHz assemblies only, coat one of the mating surfaces completely with
a very thin film of silicone grease (without additives), using an amount
about the size of a paper match head. Excessive silicone grease can
diminish performance.
3
Thread the horn stud into the converter and tighten, using spanner
wrenches.
CAUTION General Warning
Do not use silicone grease with Mylar washers. Use only 1 (one)
Mylar washer of the correct inside and outside diameters at each
interface (20kHz and 30kHz).
