2. Unscrew the powder bowl cap.
3. Remove the powder bowl from the unit and discard
the unused powder.

you, activate the system for 15 seconds to clear the
bowl. A high volume evacuator can be used to remove
any residual powder.

using a soft dry cloth, wipe residual powder from the
cap, the o-ring and the powder bowl threads. Be
careful not to scratch or otherwise damage the cap.

powder bowl.

10 2 Weekly Maintenance

• Remove residual prophy powder from the cap and bowl
threads using a soft brush (toothbrush). If not removed,
caked powder in threads can result in thread wear and
powder bowl cap disengagement.
• It is strongly recommended that this system be
disinfected by chemically flushing the waterlines with
a 1:10 Sodium Hypochlorite solution (NaOCl) at the
end of each week. This can be accomplished by
connecting this device to the Cavitron DualSelect
Dispensing System or a number of other devices
available from your local distributors. Where this device
is connected to the Cavitron DualSelect Dispensing
System, please follow the DualSelect system's Directions
for Use manual. If connected to another device, please
follow those directions for use, keeping in mind that
a chemical flush should be performed at maximum water
flow for at least 30 seconds. The system should be left
undisturbed for 10 minutes but no more than 30 minutes
to allow the sodium hypochlorite solution to soak in the
lines. As a suggestion, it is recommended that a sign
be placed on the system stating that the SYSTEM IS
BEING DISINFECTED WITH A STRONG DISINFECTANT
AND SHOULD NOT BE USED. When ready, flush system
with clean water for at least 30 seconds or until sodium
hypochlorite odor disappears. ALL CHEMICALS MUST
BE FLUSHED FROM THE SYSTEM BEFORE IT IS READY
FOR PATIENT USE.

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
JET Plus 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.
