4 Infection control
The following procedures are recommended to ensure aseptic
working environment.
Please refer to XO 4 Quick Guides for daily infection control
routines.
4.1 Disinfectants recommended for
XO 4
Always use the disinfection products described in this User
Guide. Please read paragraph 8.
Do not use any other disinfectants or cleaning pro-
ducts!
Do not soak any unit instruments or ultrasonic clea-
ner accessories in ultrasonic cleaning solutions, nor place
them in soaking basins with liquid chemicals.
Please note that failure to comply with these precau-
tions will affect XO’s warranty liability.
4.2 Disinfecting unit water lines with
XO Water Clean System (optional)
4.2.1 Dual step water treatment
The water to the unit instruments and cup filler are constantly di-
sinfected when a water treatment system has been installed.
We recommend a “Dual step” water treatment (normally step 1
– evening, and step 2 – morning) to keep the water system
clean and free from deposits:
Step 1 (evening)
1 Place all water-bearing unit instruments in the instrument
holder on the cuspidor. Place the tubing with the “T-piece”
on the cup filler outlet.
2 Activate (the expansion container is now emptied).
3 Wait for 3 minutes.The display will show the remaining time
of the process.
4 Switch off the unit and leave the unit instruments in the in-
strument holder on the cuspidor.
Step 2 (morning)
1 Check that the unit instruments are still in the instrument
holder on the cuspidor.
2 Turn on the unit.
3 The unit water lines are automatically flushed with disinfec-
tion liquid for as long as required in order to maintain a low
bacterial load (6 minutes).
The display will show the remaining time of the disinfection pro-
cess. When "FLUSH OK" appears in the display, the process
has been carried out successfully.
Please note that manual cancellation of the flushing
and expansion container water discharge process is not
possible.
Do not keep the XO Water Clean cartridge's in direct
light. Should be kept in the packing or in a closet.
Figure 14 Unit instruments in the instrument holder on the cus-
pidor
XO Water Clean cartridge (1) must be replaced at specific inter-
vals (ref. no. AN-355). When the contents in the cartridge are
under a certain level, you will hear a “warning-sound” and the
message “CHECK WHITE BOTTLE ” appears in the unit dis-
play.
Be careful not to spill the fluid. Any spills must be
wiped up at once. Then clean the surface with a damp cloth.
