Safety
1.4
Sources of Danger
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.
The risk of burns exists.
The connections and the electric heat exchanger might reach temperatures of up to
100° C.
In the case of a failure of the safety devices (safety pressure limiter and/or safety
temperature limiter and/or flow control) strong overheating of the electric heat ex-
changer is possible.
The installation of a flow control as an additional safety device is
recommended.
It prevents the heating resistor from burning out during water standstill.
If the electric heat exchanger is installed more than 0.5 m below the surface of the
bathwater, the safety pressure limiter becomes ineffective.
The installation of a flow control is prescribed in this case as an additional
safety device.
The electric heat exchanger might be damaged.
If dripping water falls onto the outer skin or if metal particles enter the electric heat
exchanger, the risk of contact corrosion exists.
1.5
Safety Measures on the Installation Site
The electric heat exchanger is to be installed in a frost-proof room with a mounting
device made of plastic or stainless steel.
Please ensure that the maximum operational overpressure of 300 kPa (3.0 bar) is
not exceeded.
The electric heat exchanger or the environment can be damaged.
Please check the electric heat exchanger and its connections for tightness and
visible damage once a week during operation.
The danger of combustion exists.
In the case of a failure of the safety pressure limiter and the safety temperature
limiter, strong overheating of the electric heat exchanger is possible. Do not store
any combustible materials in the environment.
