How often should the water filter on my Cavitron's supply hose be replaced? When the water line filter becomes discolored, the filter should be replaced to prevent reduced water flow to the system. If it is more convenient to schedule replacement of the water filter on a routine basis, our general recommendation is once per month on average. 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 the two hose fittings in a clockwise direction. Reconnect the water supply line, operate unit to bleed the air and test for leaks. |
