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.
Pleasenotethatfailureto complywiththeseprecau-
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
Thewatertotheunitinstrumentsandcupfillerareconstantlydi-
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 Waitfor3minutes.Thedisplaywillshowtheremainingtime
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 thatmanualcancellationoftheflushing
and expansion container water discharge process is not
possible.
Do not keeptheXOWaterClean cartridge'sindirect
light. Should be kept in the packing or in a closet.

play.

posits)
The“singlestep”water treatmentshouldbeusedwhenthebac-
terialloadoftheunitwaterlinesisconsideredtobetoohigh,for
instance, after vacation or other longer periods without usage.
We recommend that the single step water treatment be perfor-
med 3 consecutive times after such periods.
1 Place all water-bearing unit instruments in the instrument
holderonthe cuspidor. Placethetubewith the“T-piece” on
the cup filler outlet.
2 Activate (not ). The expansion container is emp-
tied and the water lines are flushed.

cess. When "FLUSH OK" appears in the display, the process
has been carried out successfully.
Please notethatmanual cancellationoftheflushing

4.3 Disinfecting the suction system
Thesuction valves and tubesinside the unit are constantly flus-
hed with clean water while suction is activated. However, in or-
der to maintain an aseptic working environment, the suction
system needs to be cleaned and disinfected daily.
Disinfectionandcleaningofthesuctionsystemisalsoimportant
to ensure problem-free operation of the equipment. Otherwise,
the suction system may clog up, and break down as a result.
Ifyou have chosento equipXO4 withXO SuctionDisinfection,
please proceed to section 4.3.1.
IfyourXO4doesnothaveXOSuctionDisinfection,thesystem
must be cleaned manually.
We recommend the use of the Dürr OroCup system with Dürr
Orotol Plus suction rinse.

mendtheuseofDürrMD555Orotol®specialcleanercombined

4.3.1 Flushing with XO Suction Disinfection
(optional)
Every day the suction system (valves and tubes) must be disin-
fectedbyflushingwithXOSuctionDisinfection(ref.no.AN-354).
• Disconnectthesuctiontubesandpressthebutton(2)(Figu-
re 17) once to deactivate suction.
• Remove covers from suction nipples.
• Placethetwosuctionnipplesonthedisinfectionnozzles(3)
and reactivate the push button (2), following which flushing
starts.
The process takes approximately 6 minutes, depending on the
suction power.
The suction nipple covers can be autoclaved at max. 134 oC.

If much blood has been suctioned through the sy-
stem, we recommend that the system be flushed with at
least 1 litre of cold water. After this procedure, the system
can be disinfected with XO Suction Disinfection.

4.5 Sterilizinganddisinfecting unit in-
struments and accessories
When autoclaving is mentioned in the following, the following
autoclaves may in principle be applied under the following
guidelines, cf. EN 13060:
Type N (gravitation autoclave): Massive, unpacked material
Type B (vacuum autoclave): Non-massive, packed material
and fabrics
Since a Type B autoclave can also be applied for massive, un-
packedmaterial, it is recommendedthat you always usea type
B autoclave. Since these autoclaves have better temperature
controlthroughouttheautoclaveprocess,theyalsoprocessthe
material more gently.
Please note that some instruments andaccessories are not de-
signed for thermo disinfectors or autoclaves.
The autoclaving and thermo disinfection processes
wear down the materials and may cause them to lose their
colours or shorten their lifetime.
