KEY INDICATORS THAT YOUR CAVITRON WATER FILTER NEEDS TO BE REPLACED:
• Water flow is reduced to the insert and/or handpiece
• If particulates are visible on the filter
• Discoloration of the filter
• Light indicator on your unit is visible. Valid on Cavitron Touch (G1000) and 300 Series (G310) ultrasonic scaling units only.
PLEASE NOTE:
• A 10-pack of replacement filters (part number 90158) is available from your local Dentsply Sirona distributor.
• The Cavitron water filter is not intended to be the primary water filtration for the office. It is meant to protect the
Cavitron system and components.
• If your Cavitron water filter needs to be replaced on a highly frequent basis, you should consider an overall water
filtration system for your office to minimize damage to your dental equipment.
• Please refer to the scheduled maintenance guide for your specific Cavitron system for complete maintenance recommendations.
TO REPLACE YOUR CAVITRON WATER FILTER:
1. Verify that the system is turned OFF.
2. Locate the blue waterline on the back of the unit.
3. 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.
4. Grasp the fittings on either side of the filter disk and twist counterclockwise. Remove the filter section from either side of the water hose.
5. Install the replacement filter onto the water hose fittings. The filter should be positioned to match up with the correct hose fitting.
6. 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.
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 fil-
ter 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 Sirona 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.
Powder Bowl 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.
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.
