Operating Instructions and Installation Instructions
8. Appliance description
The bare wire heating system is suitable for hard and soft water
areas. The heater has low susceptibility to scale build-up.
The appliance is suitable for heating cold water or for reheating
preheated water. For temperatures, see chapter "Specification /
Data table".
The max. inlet temperature for reheating must not be exceeded.
There will be no reheating, if the inlet temperatures exceed this
maximum value.
Observe the "Max. inlet temperature". The appliance can be
damaged at higher temperatures. If a "central thermostat" is
installed (see chapter "Installation / Accessories"), you can limit
the "Max. inlet temperature".
The outlet temperature can be infinitely adjusted. The electronic
control unit enables automatic matching of the electrical output
corresponding to the selected temperature subject to the actual
throughput.

8.2 Installation
The following conditions have been prepared for the appliance
at the factory:
- Power supply from "below", installation on unfinished walls
- Water connection, installation on unfinished walls
The appliance must be fitted vertically, over or undersink, to a
solid wall.
8.3 Temperature limiting/anti-scalding protection
The maximum temperature can be limited to 43°C via the user
interface on the appliance cap. The following steps are necessary
for this procedure:
Remove the appliance cap.
Remove the electronic PCB from the user interface on the
appliance cap. Be careful of the snap-on hooks.
Move the plug from left to right (position "43 °C").
Refit the user interface, ensuring the snap-on hooks click into
place. Observe the positions of the pushbutton and shaft.
CAUTION Burns
If operating with preheated water, the set temperature
limit and anti-scalding protection may be ineffective.
In this case, restrict the temperature at the
upstream central thermostatic valve; see chapter
“Accessories”.
