4.4. Safety valve SV1, SV2 (pressure relief valve)
1. Switch off the Daikin Altherma GSHP via the user interface.
2. Remove the front panel, refer to the Daikin Altherma ground source heat pump Installer reference guide
(EGSQH10S18AA9W).
3. Turn the brine pressure relief valve knob 1 turn and listen if brine exits for a short moment.
4. Check the brine pressure, it should be between 1 and 2 bar and stable when the pressure relief valve is closed.
5. Fill brine if required.
6. If no brine exits while turning the brine pressure relief valve knob the brine pressure relief valve must be replaced, refer to
"Replacing the water pressure relief valve" on page 110
7. Turn the water pressure relief valve knob and listen if water exits for a short moment.
8. Check the water pressure, it should be between 1 and 2 bar and stable when the pressure relief valve is closed.
9. Fill water if required.
10. If no water exits while turning the water pressure relief valve knob the water pressure relief valve must be replaced, refer to

Technical specification
Description
The pressure valve SV1 will open if the brine circuit pressure exceeds 3 bar.
The pressure valve SV2 will open if the water circuit pressure exceeds 3 bar.
A pressure relief valve is a safety component that
is designed to open at a predetermined set pres-
sure to protect the brine and water circuit.
The brine pressure relief valve SV1 is used to
limit the pressure in the brine circuit.
The water pressure relief valve SV2 is used to
limit the pressure in the water circuit.
