Program steps
The EcoRO Dia I/II (HT) has a menu-guided disinfection program. The operator is guided step by step
through the program. Function and safety-related actions to be carried out by the operator are only
triggered after manual confirmation.
The disinfection times are set as described under
part 1, chapter 14.5 “Disinfection data, menu item 5”.
WARNING
After disinfection, the dialysis personnel must check that there is no disinfectant in the
system at each dialysis station before commencing dialysis.
WARNING
At the point of connection to potable water a backflow prevention (e.g. PPBA) must be
installed!
The system must be disconnected completely from the mains supply line before disinfection
of the softener. It is absolutely essential to disconnect the RO during disinfection.
NOTICE
If total viable microbial counts in
Aquaboss
®
EcoRO Dia I/II (HT) are monitored on
a monthly base disinfection must be carried out whenever the action limit for total viable
microbial counts is exceeded but latest after 3 months (after citric acid cleaning). If the RO
system is monitored less frequently, preventive disinfection on a monthly base is recom-
mended. However, when system has not been in use for more than 72 h (system off) we
recommend disinfection. Extra disinfection is always necessary when hydraulic parts have
been opened and/or changed.
Disinfection of the device is triggered by pressing the function key D/C
in standby mode. After this, select either “Disinfection” or “Cleaning”.
After disinfection (DI) has been selected, this must be confirmed by
pressing the >
5s
< key. Then the supply tank is emptied and filled
again.
Filling with disinfectant
After the disinfectant (see
part 1, chapter 12, table 12-1 “Disinfectant
application concentration” for type and amount) has been filled into the
supply tank, the next program step is initiated by pressing the > < key.
Recirculation mode
In recirculation mode, the disinfectant is guided through all the pipe
branches by triggering the valves (and pumps).
During recirculation mode, the current conductivity is displayed in
µS/cm and the remaining time in minutes.
