7.1.3
Recondition the Stack (Converter, Booster, and Horn)
The transmission of ultrasonic energy along the stack requires a tight and clean interface
between the Converter, Booster, Diaphragm Springs and Horn.
7.1.3.1
Ultrasonic Stack Disassembly
• Be sure that Controller is off to prevent any possible electrical shock from the high voltage
contact on the converter
• Remove three screws from the back cover
• Remove the four dome nuts on the handle/ main housing top
• Clamp the ULTRASEAL 20 in a soft-jawed vise, and using the spanner wrench, unscrew the horn
from the stack
• Remove the remaining parts of the ultrasonic stack from the actuator body
• Remove the two sets of M5 X 20 mm bolts from the two polar mount clamp rings and remove the
polar mount clamp rings
• The converter can now be removed from the booster by placing one spanner wrench on the
converter and one on the booster and turning in opposite directions
• The stack is now disassembled into three main components
• The Ultrasonic Horn
• The Booster
• The Converter
• The reassembly of the ultrasonic stack is the reverse of this procedure. A torque of 85 ft-lbs is
required for the threaded connections between the horn and booster and 55 ft-lbs between the
booster and converter
