EnD .OF .THE .DAy:
Follow the "Between Patients" maintenance procedures,
Steps 1 through 6. In addition, it is recommended to close
the manual shut-off valve on the dental water supply system.
*NOTE: Water-based disinfection solutions are
preferred. Some alcohol-based disinfectant
solutions may be harmful and may discolor
plastic materials.
9.2 weekly maintenance
It is strongly recommended that this system be disinfected
by chemically flushing the waterlines with a 1:10 Sodium
Hypochlorite solution (NaOC1) 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.
9.3 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 Plus Ultrasonic Scaler. A 10-pack of replacement
filters is available by ordering Part Number 90158 from your
local authorized DENTSPLY Distributor.
1. Verify system is turned OFF.
2. 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 to drain the water.
3. Grasp the fitting 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 hose, operate
the unit to bleed the air and test for leaks.
