▶ Check Primary flow temperature. (heat transfer medium out sensor
TC3) and Return temperature (heat transfer medium in sensor TC0)
in heating mode. The flow should have a higher temperature than the
return.
▶ Calculate the differential by TC3 – TC0.
▶ Check that the differential corresponds with the set heat transfer
fluid delta.
If the temperature differential is too large:
▶ vent the heating system.
▶ Clean the filters / strainers.
▶ check pipe dimensions.
17 Environmental protection
Environmental protection is one of the Bosch group main pillars.
Results quality, efficiency and environmental protection are equally
important objectives for us. Environmental laws and regulations are
strictly adhered to.
To protect the environment we will, subject to economical aspects, use
the best possible technology and materials.
Packaging
The packaging has been labelled with country specific information about
waste disposal to facilitate optimal recycling.
All of our packaging materials are environmentally friendly and
recyclable.
Waste products
The products contain recyclable material which should be extracted and
disposed of separately.
The components are easy to take apart, and the plastic is labelled. This
allows for sorting and recycling, incineration or other disposal of the
different components.
18 Maintenance
▶ Only use genuine spare parts!
▶ Refer to the spare parts list when ordering spare parts.
▶ Always renew seals and O-rings removed during servicing or repair
work.
During service, the activities described below should be conducted.
Show alarms
▶ Check the alarm log.
Function check
▶ Perform function checks ( Chapter 16).
Electric cabling
▶ During service, the electric box may be tilted forward for easier
access.
▶ Check the cable for mechanical damage. Replace damaged cables.

Check the heating system particle filters (in the safety assembly)
The filters will prevent dirt from entering the system. Operating
problems might occur if these are blocked.
Cleaning the strainer
▶ Close the valve (1).
▶ Screw off the hood (by hand), (2).
▶ Take out the strainer and clean it by running water over it or by
pressure cleaning.
▶ Put the strainer back; it has rails that fit into the groove in the valve to
avoid incorrect installation (3).
DANGER: Electric shock!
▶ Switch off the main power supply before starting
work on the electrical part.
NOTICE: Risk of deformation due to heat!
The heat pump module insulation material (EPP) will
deform if it is exposed to high temperatures.
▶ Only use heat protection cloth or wet cloth to protect
the insulation material while performing soldering
work on the heat pump module.
It is not necessary to empty the installation in order to
clean the filters. Filter and shut-off valve are integrated.
