ᐅ Decommissioning a Spartec heat pump

Hello,
we want to deactivate our Spartec heat pump with a ground collector.
Now we have the problem that we cannot find the withdrawal point for the coolant. Could someone perhaps give us some advice?
The model was only produced briefly and installed in few cases; the manufacturer has not existed since 2008.
The user manual only states that it must be done by professional companies.
However, most companies find an unknown model too complicated.

Best regards,

If you want to drain the coolant, you need someone with a refrigeration certification. It’s not something you should handle yourself!

Hello,
I do not want to do it myself. So far, no tradesperson has been able to locate the spot. Therefore, I am hoping for tips on where it is, so the tradesperson can proceed.
Best regards
