Functional Course

In the electric heat exchanger, heat is transferred to the bathwater through the
heating element.
The thermostat regulates the water temperature in accordance with the adjusted
value, range from 0 to 40°C.
EWT 80-40/-70: If the required operating overpressure falls to below 6 kPa
(0.06 bar) due to insufficient water throughput, the safety pressure limiter switches
off the electric heat exchanger.
EWT 80-41/-71/-T/-81: If the required overpressure falls to below 36 l/min. due to
insufficient water throughput, the Flow switch switches off the electric heat exchanger.
Special made with safety temperature limites: The safety temperature limiter protects
from overheating. It switches the electric heat exchanger off at a temperature of 44°C.
By pressing the disorder button, the electric heat exchanger can be put into normal
operation again after removal of the disorder.

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 per-
sonnel for safety reasons.
caution
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.
take care
Do not step on the electric heat exchanger.
Only carry out work in the piping connections with closed blocking and control
units in the water cycle!
