Heat pump at basement light shaft - How to insulate?

The device is located in the corner of the basement room; i.e. the light shafts are connected directly to the device around the corner... without additional cables.

Pipes branch off to the right. They are probably for the underfloor heating, right?

Yep... underfloor heating, warm water and return flow... yes and the channel drain... the photo is already somewhat older and shows the device without the associated insulation and the cover... the device itself is also insulated again by about 10-15cm with a complete cover.

Ah okay, I thought so! What kind of botching was going on there.
