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.

Maintenance/Repair

• Check the heat exchanger and its connections for their tightness once a week
and ventilate the entire water cycle.
The electric heat exchanger can be damaged.
Work in the electrical heat exchanger are only to be effected by specialist personnel
for safety reasons.
Do not step on the electric heat exchanger.
Only carry out work in the piping connections with closed blocking and control units

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
• Remove heat exchanger with horizontal layout.
• Flush heat exchanger in order to remove contamination and store in a dry place.
