10.3 Monthly Maintenance

WATER LINE FILTER MAINTENANCE:

When the water line filter becomes discolored, the filter
should be replaced to prevent reduced water flow to the
Cavitron Prophy-Jet System. A 10-pack of replacement
® ®
filters is available by ordering Part Number 90158 from your
local DENTSPLY Professional distributor.
1. Verify that the system is turned OFF.
2. Disconnect the water supply hose from the dental
office water supply. 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.
3. Grasp the fittings on either side of the filter disk and
twist counterclockwise. Remove the filter section
from either side of the water hose.
4. Install the replacement filter onto the water hose
fittings. The filter should be positioned to match up
with the correct hose fitting.
5. Hand tighten one hose fitting onto filter in a clockwise
direction. Tighten second hose onto filter in clockwise
direction. Reconnect the water supply line, operate unit
to bleed the air and test for leaks.
10.4 Air Supply Line Filter Maintenance
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 (some filters drain by
depressing the Schrader valve stem at the bottom of the
filter). If the inner filter element becomes discolored or dirty,
a new filter assembly should be installed. Replacement filter
assemblies are available by ordering Part Number 90088
from your local DENTSPLY Professional distributor.
1. Verify that the system is turned OFF.
2. Disconnect the air supply line from the dental office air
source.
3. Using a 7/16" 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.
4. 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.
5. Turn the System ON, operate the system and check
for leaks.
10.5 Powder Bowl Maintenance
1. Turn the System OFF.
2. Allow the powder bowl to depressurize and unscrew
the Powder Cap.
3. Empty powder from the bowl and use the high suction
to remove any residual powder in the bowl.
4. Turn the System ON and check for strong air flow
from the center tube of the powder bowl.
5. If no or low air flow is present, turn the System OFF.
6. Unscrew the knurled ring at the bottom of the bowl
assembly and remove the fitting assembly.
7. Using the JET Air Polishing Insert nozzle cleaning wire
tool, clean clogged powder from the fitting assembly.
Turn the System ON and check for strong air flow.
Turn the system OFF.
8. Check that the o-ring is properly positioned in the
groove of the fitting assembly and reassemble the
fitting assembly to the bowl. Tighten knurled ring.
Place powder bowl into System.
9. Fill the powder bowl with fresh prophy powder and test
for flow and leaks.
10. Remove residual powder from thread on the cap and
bowl with a soft, dry cloth.
