Fittings technology
The facility for thermal disinfection must be guaranteed during the planning of
sanitary installations, in accordance with the "Recognised Rules of Technology" as
per the DVGW Worksheet W 551.
Thermostatic fittings provide the facility for thermal disinfection. An additional bypass
solenoid valve cartridge in the function block of the fitting connects the hot water
inlet to the mixed water take-off on the fitting.

Planning instructions
The thermal disinfection must be carried out in sections, depending on the structural
situation. Groups of fittings must be established for this purpose. For example, a
group of fittings must be created, such as shower fittings in a room that need to be
flushed when starting the thermal disinfection.
The criteria for determining the groups of fittings are:
– The volume of the hot water heater
– The size of the installation
– Spatial criteria (e.g. fittings group 1 = men's shower room - 1st floor)
– Volume flow of the bypass solenoid valve cartridge (V = 0.06 l/s)
– Power consumption of the bypass solenoid valve cartridge e.g. 2 W
For detailed information for planning an installation with automatic thermal disin-
fection, please contact our Customer Service department, or request the AQUA
3000 open-system documentation.

Safety instructions
Warning!
Personal protective measures (scald protection) must be implemented for the
duration of the thermal disinfection. This might include cordoning off the shower
facilities.
Failure to observe this instruction can result in injuries due to scalding.
The operator is responsible for the execution, monitoring, and logging (room,
tapping point, date, time, temperature and duration).
The manufacturer does not accept any liability for claims by third parties relating to
the improper execution of thermal disinfection on the part of the operator.
