All incoming water is filtered (50 μm), eliminating particles from main water supply.
Incoming compressed air is filtered (5 μm).
A main water valve automatically switches water on/off when activating the main switch. A leakage sensor provides automatic shut-off of water supply if an internal water leak is detected.
An integrated water softener decarbonizes water for use in the XO unit and protects the internal components of the unit by reducing the limescale content. Furthermore, the taste of the water is improved by removing unpleasant odors and tastes, e.g. chlorine.

5 WATER ACCESSORIES

5.1 XO WATER DISINFECTION

XO Water Disinfection continuously dispenses a solution of non-toxic disinfectant containing hydrogen peroxide (working strength solution contains 0.0235% hydrogen peroxide) to the procedural water. The disinfectant is proven to keep the number of microorganisms in the unit at a level suitable for drinking water. The cartridge holder is accessible from the outside through one of the service panels and allows for quick replacement of disinfection cartridges by clinic personnel. The users are notified on the instrument bridge display when the level of disinfectant is low.

XO Water Disinfection further hinders limescale from forming by binding the calcium carbonate.
XO Water Disinfection is supplied with a disinfection instrument holder.
Two types of disinfection routines are available:

Overnight disinfection:

• At the end of the work day the water container and unit’s waterlines are emptied
• At the beginning of the next work day the water container is filled and the unit water lines are flushed with disinfectant

Intensive disinfection for use after weekends, holidays or longer periods where the unit has not been used:

• The water tank is emptied
• The water tank is filled again using a double dose of disinfectant
• The unit water lines are flushed with a double dose of disinfectant

The disinfection liquid used by XO Water Disinfection is available in cartridges containing 0.6 liter (enough for 60 liters of procedural water).
Specifications – see XO Water Disinfection safety data sheet.
XO Water Disinfection cartridges – 6 x 0.6 liter (AO-980)

5.2 BACKFLOW PREVENTION

The backflow prevention provides a vertical air gap of 20 mm for preventing procedural water from flowing back into the municipal water supply system.
It contains a water tank with a capacity of approx. 1 liter that provides pressure to the water that has passed through the air gap. The water tank is filled when there is no demand for procedural water.
A suitable method for preventing contaminants from flowing back into the municipal water supply is required by law within the EU. Without the backflow module the XO unit does not fulfill the requirements of ISO 7492-2 and EN 1717.

5.3 NO CUSPIDOR AND CUP FILLER

The XO FLEX unit may be supplied without cuspidor and cup filler.
Please note: XO Water Disinfection cannot be installed on units without cuspidor and cup filler.
