Central Automatic Chemical Disinfection
The hypochlorite disinfectant Tiutol KF must be applied (mixing ratio
maximum 65 ml Tiutol KF per litre).
The user is responsible to integrate the dialysis machine in the dialysis
centre’s central water loop system, if the
Central Automatic Chemical
Disinfection
is used.
The retention time must be ≤ 10 hours if the retention is disabled, i.e. the
Retention Time is set to YES , thus, no Central Automatic Chemical
Disinfection
.
This disinfection method can be used for the
disinfection of the water inlet line in dialysis
centres with central water loop systems.
A defined inlet volume (disinfectant) from the
water loop line is sucked in as follows (see dotted
lines in the flow diagram):
• FPA/UFP decrease the water level in the
upline tank VB to the lower level sensor
NSVB
• The upline tank VB (approx. 260 ml inlet
volume) is filled with disinfectant to the
upper level sensor NSVB, due to the water
pressure at VVBE from
• the central water loop system
• Filling is repeated until the preselected
volume is reached
• Retention time (machine is switched off)
• Rinsing via VB, RVE, VLA, LA and FPA to the
outlet
Phase 1
• machine is filled and emptied 5 times, i.e the disinfectant is volume
controlled and sucked in and emptied by the central water loop line
Phase 2
• cyclic rinsing (time controlled -- rinsing time and rinsing flow
