Safety Equipment - Behncke EWT 60-20 Betriebsanleitung

Safety
The installation of a flow control as an additional safety device is recommended.
It prevents the heating resistor from burning through during a water standstill.
The electric heat exchanger can be damaged.
The electric heat exchanger may only be put into operation if it has been ensured
that the electric heat exchanger is continuously supplied with water during operati-
on. The water throughput must be at least 1000 l/hour.

Safety Equipment

The warning sign on the electric heat exchanger refers to the dangers due to elec-
tric current.
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
To switch the heating element an external contactor is necessary (from 3 kW power,
from 2 kW recommended).
The safety devices switch off the electric heat exchanger if impermissible values are
reached.
