6.1 Checking the operating pressure, topping up the heating water and venting the system
6.1.1 Checking the operating pressure
Your heating contractor will have set the red needle of the pressure gauge [1] to the required operating pressure (at least 1 bar) and will have recorded this value in table 8, page 14.
▶ Check that the pressure gauge needle [2] is within the green
band [3}.
▶ If the pressure gauge needle drops below the green band, top up the
heating water.
Fig. 17 Pressure gauge for sealed systems

6.1.2 Topping up the heating water and venting the system
CAUTION:
Health risk through contaminated drinking water!
▶ Obser ve all country-specific regulations and standards regarding the
prevention of drinking water contamination.
▶ In Europe, observe standard EN 1717.
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.
NOTICE:
System damage due to frequent topping up!
If you have to top up the heating water frequently, the heating system may suffer damage through corrosion or scaling, depending on the water quality.
▶ Ask a certified heating contractor if the local water can be used
untreated or whether it needs to be treated.
▶ Notify your heating contractor if you frequently need to top up your
heating system.
Topping up heating water is different for individual heating systems. Therefore, ask your approved contractor to advise you accordingly.
The refill quantities must be documented in the operator's log.
6.2 Switching on the heating system
Observe technical documentation of the installed control unit.
Before switching on (Chapter 3.1), ensure that:
• the operating pressure is high enough,
• the fuel supply has been turned on at the main shut-off valve, and
• the heating system emergency stop switch is switched on.
7 Shutting down the heating system
7.1 Shutting down the heating system via the control unit
NOTICE:
Frost damage!
If the heating system is not standing in a frost-proof room and is not in operation, it may freeze up when exposed to frost. In summer mode or if heating mode is blocked, only the device frost protection remains active.
▶ Leave the heating system switched on at all times whenever possible,
and set the flow temperature to at least 30 °C,
-or-
▶ Protect the heating system against frost by having the heating and
DHW pipes drained by a contractor from the lowest point.
▶ Shutting down the heating system via the ON/OFF switch at the
control unit (Chapter 3.1).
7.2 Shutting down the heating system in an emergency
Only use the boiler room circuit breaker or heating system emergency stop switch to switch off the heating system in an emergency.
▶ Never risk your own life. Your own safety is paramount. ▶ Close off the fuel supply installed on site. ▶ Isolate the heating system from the mains power supply via the
heating system emergency stop switch or the main circuit breaker.

8 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.
9 Inspection and maintenance
9.1 What makes regular service important?
Heating systems should be regularly serviced for the following reasons:
• To maintain a high level of efficiency and to operate the heating
system economically (low fuel consumption)
• To achieve a high level of operational reliability
• To maintain the cleanest possible combustion
NOTICE:
Material damage due to a lack of or incorrect cleaning and service.
▶ Have the heating system inspected, maintained and cleaned once a
year by a certified heating contractor.
▶ We recommend you enter a contract covering an annual inspection
and demand-based maintenance.
9.2 Cleaning and care
To clean the boiler: ▶ Do not use abrasive or aggressive cleaning agents. ▶ Clean the casing with a damp cloth (soapy solution).
10 Troubleshooting
10.1 Recognising the operating condition and clearing faults
NOTICE:
Frost damage!
If the heating system is not standing in a frost-proof room and is not in operation, it may freeze up when exposed to frost. In summer mode or if heating mode is blocked, only the device frost protection remains active.
▶ Leave the heating system switched on at all times whenever possible,
and set the flow temperature to at least 30 °C,
-or-
▶ Protect the heating system against frost by having the heating and
DHW pipes drained by a contractor from the lowest point.
If a fault has developed, the fault code flashes on the control unit display. For more information on rectifying the problem or on possible faults,
refer to the corresponding technical documentation of the installed control unit.
If the fault cannot be cleared:
▶ Note down the fault message and notify a heating contractor.
