5.1.1
▶ Check the pressure on the pressure gauge. The pressure is also
shown in the system overview on the display ( Chapter 2.7).
▶ If the pressure is lower than 0.6 bar, slowly increase the pressure in
the heating system by adding water through the filling valve to a
maximum of 2 bar.
▶ Contact your installer or Worcester Bosch technical help line, if you
require assistance with increasing the pressure.
5.1.2
Strong magnet!
Can be harmful to pacemaker wearers.
▶ Do not clean the filter or check the magnetite indicator if you have a
pacemaker.
The particle filter prevents particles and contamination from entering
the heat pump. Over time, the filter can become blocked and must be
cleaned.
To clean the filter, the system does not need to be emptied. The filter and
shut-off valve are integrated.
As the filter is installed vertically, the PC0 pump needs to be running
when the lever is closed. Ensure the compressor or additional heater are
not running when the lever is closed to avoid damaging components.
This can be done by entering the function test and running the PC0
pump. Then follow the steps below. Do not enter the function test if the
compressor is running!
Cleaning the strainer
▶ Close the valve (1).
▶ Unscrew the cap (manually) (2).
▶ Take out the strainer and clean it by running water over it or by
pressure cleaning.
▶ Reinstall the strainer. For proper assembly, make sure that the guide
bumps fit into the recesses in the valve.
