Initial Operation

Have you read and understood these operating instructions - in particular chapter
1, Safety? Only then are you allowed to start the electric heat exchanger.
• Adjust the desired bathwater temperature in the thermostat.
The electric heat exchanger heats the bathwater as long as the adjusted tempera-
ture has not been reached,
The electric heat exchanger can be damaged.
Work in piping and electrical installation are only to be effected by specialist person-
nel for safety reasons.
Do not step on the heat exchanger.
Only carry out maintenance and repair work with closed blocking and control units
in the water cycle.
• Ventilate the entire water cycle, otherwise can the heating element harm to take.

6.1

Hibernation of the EWT in Frost-proof Rooms

Intervention in technical systems by unqualified persons might lead to injury or
damage.
For hibernation in frost-proof rooms, the electric heat exchanger must be complete-
ly filled with water or be completely drained.
6.2

Hibernation of the EWT in Non Frost-proof Rooms

Expert hibernation without frost damage is possible if the following steps are observed:
• C lose blocking units in the water cycle (the blocking units must be installed in
frost-free rooms).
• Flush and drain electric heat exchanger and adjoining pipes until blocking units.
6.2.1 Electric Heat Exchanger with Horizontal Layout
