It is the responsibility of the supervisor to make sure that:
1. An appropriate Risk Assessment is carried out in accordance with the local or national regulations.
2. The water temperature is raised to and held at the required level at all parts of the circuit for the required duration
as stated in the Risk Assessment.
3. All outlets are ushed for the correct amount of time if required by the Risk Assessment.
4. Appropriate measures are taken to make sure that none of the outlets are used while the water is at an unsafe
temperature.
5. Once thermal disinfection is complete, the supervisor should return the DRV25 to its normal operating mode
using the Cool Down button within the Disinfection screen. This will switch the DRV25 to its full cold position
and allow the blend circuit to be reduced gradually to a safe temperature level*. Make sure the blend circuit
temperature returns to normal operation within the Disinfection Timeout period (see page 21).
6. The Disinfection cycle is monitored constantly and the supervisor is able to stop the cycle using the Abort button
in the Disinfection screen.
7. In the event of the user failing to enter cool down mode within the Disinfection Timeout period, the DRV25 will
automatically enter the cool down phase for 5 minutes.
*Without a draw o, the water in the blend circuit will remain hot for a long time. In order to speed up the temperature
reduction, a draw-o must be made during Cool Down using the last outlet of the blend circuit, or a dump valve
tted near to the end of the blend circuit. Check with local water authorities with regard to water temperature
limitations to drain.
Failure to complete a sucient cool down of the blend circuit may result an Error Temp shut down to full cold.

The thermal disinfection mode of the DRV25 is not an automated process. It is manually activated by the supervisor
to increase the temperature of the blend circuit to equal the temperature of the hot supply. The circuit pipework and
outlets can be thermally disinfected as part of a bacterial infection control regimen.
DO NOT USE THE THERMAL DISINFECTION FEATURE IF THE HOT WATER SUPPLY
CAN EXCEED 185°F (85°C)!
THE MAXIMUM TEMPERATURE FOR DISINFECTION SETPOINT MUST BE 185°F (85°C).
NE PAS UTILISER LA FONCTIONNALITÉ DÉSINFECTION THERMIQUE SI
L’ALIMENTATION EN EAU CHAUDE PEUT ALLER AU DELÀ DE 180°F (85°C)!
LA TEMPÉRATURE MAXIMALE POUR LE POINT DE CONSIGNE DE DÉSINFECTION
DOIT ÊTRE DE L’ORDRE DE 185°F (85°C).
Thermal Disinfection
Warning! Thermal disinfection is a potentially hazardous process to raise the water
temperature to a level that will scald or even kill. It is therefore the responsibility of
the person supervising the process to make sure it is carried out correctly and safely.
Avertissement! La désinfection thermique est un processus potentiellement
dangereux pour augmenter la température de l’eau à un certain niveau pouvant
brûler ou même tuer. Il revient donc à la personne en charge de la supervision de
cette opération de s’assurer qu’elle se déroule correctement et en toute sécurité.
ALL DRV25 ALERTS AND ERRORS ARE DISABLED DURING THE PROCESS!
