Troubleshooting
Although service and repair of the Cavitron JET Plus
Combination System should be performed by DENTSPLY
personnel, the following are some basic troubleshooting
procedures that will help avoid unnecessary service calls.
Generally, check all lines and connections to and from
the System. A loose plug or connection will often create
problems. Check the settings on the System's controls.

If the office has more than one Foot Control, test
each to ensure that the proper Foot Control is being
used. With a handpiece and insert installed, depress
the Foot Control to the first position. The system
should dispense water. If none of the Foot Controls
operate the system, continue to the next step.

System, check that fluid level in the selected bottle is
sufficient. Make sure valves are open when using
external water source.

filter if needed.

Mode.

Check the insert for damage and that it is properly
installed in the handpiece.
