* Larger cable cross-sections may be required depending on the connection configuration.
** The pressure loss on the mixer must also be added.
Solar heated
The appliance can only heat prewarmed water to a max. of 60 °C.
If the cold water supply exceeds a temperature of 55 °C, the water
will not be warmed any further.
Important: The cold water supply temperature must not be higher
than 55 °C!
If the cold water supply exceeds a temperature of 60 °C, a circuit breaker
will trigger and shut the appliance off. Therefore, the residential
plumbing must be equipped with a thermostatic premixer (e. g. special
accessory BZ 45T20) that will limit the cold water supply temperature
to a max. of 55 °C by appropriately mixing in cold water.

Environmental protection/disposal

Environmental protection is a fundamental corporate strategy of the
Bosch Group.
The quality of our products, their economy and environmental safety are
all of equal importance to us and all environmental protection legislation
and regulations are strictly observed.
We use the best possible technology and materials for protecting the
environment taking account of economic considerations.
Packaging
Where packaging is concerned, we participate in country-specific
recycling processes that ensure optimum recycling.
All of our packaging materials are environmentally compatible and can be
recycled.
Used appliances
Used appliances contain valuable materials that can be recycled.
The various assemblies can be easily dismantled. Synthetic materials are
marked accordingly. Assemblies can therefore be sorted by composition
and passed on for recycling or disposal.
Used electrical and electronic appliances
Electrical or electronic devices that are no longer
serviceable must be collected separately and sent for
environmentally compatible recycling (in accordance with
the European Waste Electrical and Electronic Equipment
Directive).
To dispose of old electrical or electronic devices, you
should use the return and collection systems put in place in the country
concerned.
Batteries must not be disposed together with your household waste.
Used batteries must be disposed of in local collection systems.
Subject to change without notice.
