The delivery took place at the agreed date. I had to unpack the device itself.
A surprise was the covered back (see customer images) - because the cover is screwed, no obvious transport cover (as then an Internet search confirmed). Apparently the producers want to avoid performance degradation by dusting thereby. Since the refrigerator behind the cooling fins are missing, the heat must be derived differently: apparently on the side walls. The manual recommends 10 cm square in * all * directions, and the side walls with active compressor running even lukewarm. Optimally, the refrigerator should therefore not be installed (otherwise the adjacent cabinet walls must absorb the heat).
Nevertheless, a decent device.
