9 Environment / disposal
Environmental protection is a fundamental corporate strategy of the
Bosch Group.
The quality of our products, their efficiency 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 into account of economic considerations.
Packaging
We participate in the recycling programmes of the countries in which our
products are sold to ensure optimum recycling.
All of our packaging materials are environmentally friendly and can be
recycled.
Used appliances
Old appliances contain materials that must be recycled.
The relevant assemblies are easy to separate and all plastics are marked.
In this way the individual assemblies can be easily sorted and directed to
recycling or disposal.
10 Inspection and servicing
Heating systems should be regularly serviced for the following reasons:
• to maintain a high level of efficiency and to operate the system
economically (low fuel consumption),
• to achieve a high level of operational reliability,
• to maintain the cleanest possible combustion
• to ensure reliable operation and a long service life.
Maintenance work must only be carried out by authorised contractors.
Only use original spare parts. The system should be serviced annually.
The results of the services must be recorded in the inspection and
maintenance report.
Offer your customer an annual contract covering inspection and
demand-dependent servicing. The work that needs to be included in a
maintenance contract is detailed in the inspection and maintenance
reports (

chapter 10.14, page 43).
10.1 Preparing the boiler for inspection
▶ Shutting down the heating system.
▶ Undo the locking screw from the top centre of the boiler front panel.
▶ Slightly lift the front panel and remove by pulling forwards.
NOTICE: Risk of damage to the system from frost!
When the heating system is switched off, it can freeze up
if there is frost.
▶ In case of a risk from frost, protect the heating
system against frost damage. To do so, drain the
heating water at the lowest point of the heating
system. Do this by opening the air vent valve at the
highest point in the heating system.
Only in emergencies, shut down the heating system via
the installation room fuse/circuit breaker or the heating
system emergency shut-off switch.
Refer to the spare parts catalogue when ordering spare
parts.
DANGER: Risk to life from electric current!
▶ Before opening up the boiler, isolate it completely
from the mains power supply and ensure the power
cannot be inadvertently reconnected.
DANGER: Risk to life through explosion of flammable
gasses!
▶ Only registered gas fitters are permitted to carry out
work on gas lines (observe local regulations).
