Help with refrigeration installation

[Ken Pole]

As a replacement for the original poorly-insulated icebox in my C&C 27, I'm planning to install a Dometic drawer refrigerator this spring. However, I'm perplexed by a warning in the manual that I need to ensure a minimum 50mm ventilation on "all four sides of the cooling unit." Since mounting the unit requires fastening into bulkheads on either side, how can I ensure the air flow is not restricted? I plan to mount the compressor on a shelf well below the drawer as close to the hull as practicable. Dometic tech support seems to consist of "read the manual". Any advice would be appreciated, please -- and thankyou.

Dumb-ass question! After further research, I've decided that I'm conflating the refrigerator itself with the "cooling unit", i.e. the compressor. So please ignore my original misguided call for help.
