Decommissioning when there is a risk of frost

If the appliance remains switched off:
▶ Make sure that a sufficient flow rate is possible at all radiators.
If the wall mounted gas condensing boiler is switched off:
▶ Put the ON/OFF switch at the control panel to position "0".
▶ Close the gas valve under the wall mounted gas condensing boiler.
▶ Drain the entire heating system.

H Inspection and service
The system operator is responsible for ensuring the
heating system is used safely and in an
environmentally-sustainable manner.
If maintenance or inspections are omitted or
incorrectly carried out, this can cause personal injury
and even danger to life or material damage.
▶ Have work carried out only by an approved
contractor.
▶ Have the heating system inspected by an approved
contractor at the defined maintenance intervals.
( Inspection and maintenance interval, p. 3).
▶ Have the necessary maintenance carried out
directly.
▶ Have defects in the heating system rectified
immediately irrespective of the specified
maintenance interval.
Topping up the heating water
Topping up the heating water is different on every heating system. You
should therefore ask your specialist to show you how it is done.
NOTICE
Material damage due to thermal stresses!
When topping up a hot boiler with cold heating water, thermal stresses
can lead to cracking due to internal stress.
▶ Only fill the heating system when cold. Maximum flow temperature
40 °C.
Maximum pressure of 3 bar at maximum heating water temperature
must not be exceeded (pressure relief valve will open).
Bleeding radiators
If radiators heat up at different rates:
▶ Bleed radiators.

Environmental protection and 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.
Old electrical and electronic appliances
electronic equipment regulations apply, e.g. "European Directive 2012/
19/EC on old electronic and electrical appliances". These regulations
define the framework for the return and recycling of old electronic
appliances that apply in each country.
