this would indicate an air leak. To correct, turn the Unit OFF,
remove the Fill Cap, clean any residual powder from the O-ring
seal and threads, replace the Fill Cap, tighten, and turn the Unit
back ON.

9.2 Weekly Maintenance

Using a soft brush (toothbrush), remove residual prophy powder
from the cap and bowl threads. If not removed, caked powder in
threads can result in thread wear and cap disengagement.

9.3 Lavage Filter Maintenance

When the Lavage filter becomes discolored, the filter should
be replaced to prevent reduced water flow to the Cavitron
JET Combination System. A 10-pack of replacement filters
is available by ordering Part Number 90158 from your local
®
DENTSPLY distributor.
1. Disconnect the water supply hose from the water source.
If a quick-disconnect connector is attached to the end of
the hose, relieve the water pressure by pressing the tip of
the connector in an appropriate container and draining
the water.
2. Grasp the fittings on either side of the filter disk and twist
counterclockwise. Remove the filter section from either side
of the water hose.
3. Install the replacement filter onto the water hose fittings. The
filter should be positioned to match up with the correct hose
fitting.
4. Hand tighten the two hose fittings in a clockwise direction.
Reconnect the water supply hose, operate the unit to bleed
the air and test for leaks.
9.4 Powder Chamber Air Filter
Maintenance
There is a user-replaceable duckbill air filter attached to the side
of the powder chamber. If this filter becomes discolored or dirty,
it should replaced. New duckbill air filters (#60367) may be
purchased through your local DENTSPLY Professional distributor.

of the filter counter-clockwise to open. After draining, turn
the knob fully clockwise to close. If the inner filter element
becomes discolored or dirty, a new filter assembly should be
installed. A new filter assembly (#90088) may be purchased
through your local DENTSPLY Professional distributor.

fittings of the filter. Unscrew the nuts and slide them down
the hose. Disconnect hoses from the filter and discard the
used filter.
3. Insert the short hose into the input port of the filter and the
long hose into the output port of the filter. Slide the nuts up
the hoses and screw onto the fittings. Tighten using pliers or
a wrench.
