Safety
The warning sign on the electric heat exchanger refers to the dangers due to elec-
tric current.
The electric heat exchanger is equipped with a safety pressure limiter. The safety
pressure limiter serves as a low-water safeguarding device.
The electric heat exchanger must be protected by at least two safety circuit brea-
kers.
The following combinations are offered by the factory
– with a control thermostat
– with a control thermostat and a safety temperature limiter
take care
– with a safety temperature limiter and a contactor of up to 12 KW.
If no contactor has been installed by the factory, an external protection for swit-
ching the heating element is necessary (e. g. Behncke control for EWQT 80-xx).
The safety devices switch off the electric heat exchanger if impermissible values
are reached.
