If powder fluffing is observed when Foot Control is not in use,
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 premature 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
®
PROPHY-JET unit. 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 drain 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 pur-
chased through your local DENTSPLY Professional distributor.

disconnect the tubing from the bottom (small end) of the
filter. Slide filter from the bracket. Then disconnect the
clear tubing from the top (large end) of the filter and discard.
4. Connect the longer clear tubing from the side of the
chamber to the top of the new filter and slide filter into
the bracket. Connect the smaller clear tubing from the
bottom of the chamber to the bottom of the filter. Ensure
tubing is fully seated on filter ports.
5. Replace the powder chamber in the system.
6. Operate the system and check for leaks.

Water build up in the air supply line filter should be drained.
This can be accomplished by turning the knob on the bottom
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.
1. Disconnect the air supply line from the air source.
2. Using pliers or a wrench, loosen the nuts on the side 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.
