4.2.2
Single step water treatment (heavy de-
posits)
The “single step” water treatment should be used when the bac-
terial load of the unit water lines is considered to be too high, 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
holder on the cuspidor. Place the tube with the “T-piece” on
the cup filler outlet.
2 Activate
(not
). The expansion container is emp-
tied and the water lines are flushed.
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.
4.3
Disinfecting the suction system
The suction valves and tubes inside 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.
Disinfection and cleaning of the suction system is also important
to ensure problem-free operation of the equipment. Otherwise,
the suction system may clog up, and break down as a result.
If you have chosen to equip XO 4 with XO Suction Disinfection,
please proceed to section 4.3.1.
If your XO 4 does not have XO Suction Disinfection, the system
must be cleaned manually.
We recommend the use of the Dürr OroCup system with Dürr
Orotol Plus suction rinse.
If the suction tubes or drain contains heavy deposits, we recom-
mend the use of Dürr MD 555 Orotol® special cleaner combined
with the Dürr OroCup.
In either case, please be sure to follow the instructions given by
Dürr.
Do not use any other disinfectants or cleaning pro-
ducts! Please note that failure to comply with this will affect
XO’s warranty liability.
4.3.1
Flushing with XO Suction Disinfection
(optional)
Every day the suction system (valves and tubes) must be disin-
fected by flushing with XO Suction Disinfection (ref.no. AN-354).
• Disconnect the suction tubes and press the button (2) (Figu-
re 17) once to deactivate suction.
• Remove covers from suction nipples.
• Place the two suction nipples on the disinfection nozzles (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
