Service - Branson DHA-1000 Operator's Manual

The ultrasonics will begin immediately to remove the lead from the slide.
All lead should be removed within 10 seconds. If your cleaner passes
this test, its ultrasonic cavitation is acceptable.
NOTE:
To ensure consistency from test to test, be sure to repeat
test conditions - use the same solution concentration, liquid level,
temperature, type of pencil, length of degassing, etc.

Service

With normal use, your Ultrasonic Cleaner should not require servicing.
However, if it fails to operate satisfactorily, first try to diagnose the
problem by following the suggestions in the Troubleshooting Guide.
If you find that your cleaner needs repair, carefully pack and return it to
your local distributor. If under warranty, remember to include proof of
purchase. Your cleaner will be returned by ground service unless you
specify otherwise.
