Note
The groundwater station should only be commis-
sioned if there is a sufficient flow rate on the heat
source side.
f
Also observe the flow rate pressure drop diagrams in
chapter "Specification".
f
Check that the hydraulic connection has been carried out
correctly.
5. Appliance handover
f
Make the user familiar with the appliance and hand them
this manual for safekeeping.
6. Cleaning, care and

f
Flush the heat exchanger with clean water. For this, use
15x the volume of the content on the heat source side.
f
Turn 3-way ball valve levers 90° to the right so they are
back in line with the direction of flow.
f
Remove flushing unit.
f
Refit screw caps on connectors.
