13. Hot disinfection
Hot-water disinfection is a chemical-free supplement to tried-and-trusted methods of disinfection which
optimises the microbiological quality of the permeate. Hot cleaning is carried out in standby operation.
13.1 Hot disinfection of the loop
An additional external hot disinfection system (e.g. Aquaboss® HotRinse SMART) makes it possible to
sanitise the loop with hot water.
Since permeate from reverse osmosis can be supplied in this operating state and no dialysis operation is
permitted, the activated hot cleaning is indicated in the display of the EcoRO Dia I/II (HT).
13.2 Hot disinfection of the loop and reverse osmosis
Regular hot disinfection can be triggered automatically through the weekly program ( see Menu 12,
Automatic operation) or started manually ( see Menu 12, Manual operation).
The basic requirement for implementation is always standby operation of the reverse osmosis system and
release through the external hot disinfection system.

NOTICE
Hot disinfection is not possible in the “off” operating state.
NOTICE
Effectiveness of the system in killing bacteria can only be achieved at temperatures
> 80°C and a contact time of min. 20 minutes.
IMPORTANT Only use heat resistant materials for the fluid pathway to be disinfected with hot water.
Active hot cleaning is indicated in the display. A distinction is made
between the operating phases “heat up”, “hold temperature” and “cool
down”.
In addition, the current operating temperature(s) are indicated on the
reverse osmosis system (TISAH1, TISAH2).
