Electric Heat Exchanger / Safety Safety 1.1 Risks When Handling Electric Heat Exchanger The electric heat exchanger has been built on the basis of state-of-the-art technology and the approved safety-technical guidelines. Nevertheless, risks might occur during use such as – violation of operator or –... -
Page 5: Intended Use
The electric heat exchanger is exclusively designed for heating bathwater with activated recirculating or filter pump. Any other mode of application is not regarded as intended use. The manufacturer Behncke ® GmbH is not liable for any resulting damage. Other uses are only possible upon agreement with and approval by the manufacturer. -
Page 6: Sources Of Danger
Electric Heat Exchanger / Safety 1.4 Sources of Danger TAKE CARE The electric heat exchanger can be damaged. If the maximum operational pressure of 300 kPa (3.0 bar) is exceeded, the electric heat exchanger might develop leaks. TAKE CARE There is a risk of burns. The connections and the electric heat exchanger might reach temperatures of up to 100°... -

When installed either 0,5 m above or below the water-level the manometric safety switch (low-water safety device) loses its effectiveness. In this event, instead of a manometric switch, it is absolutely necessary to fit a Behncke ® flow switch (see EWT 80-41/-71). -

– with a contactor up to 12 kW. If no contactor has been installed by the factory, an external protection for switching the heating element is necessary (e. g. Behncke control for EWT 80-xx). IMPORTANT It should be ensured that the electric heat exchanger can only be switched on if the water throughput is ensured. -
Page 19: Functional Course
Electric Heat Exchanger / Functional Course Functional Course In the electric heat exchanger, heat is transferred to the bathwater through the heatingelement. 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. -
