We are the seconed of a 1997 Beneteau Oceanus 321 .One of the first upgrades was to add a refrigeration unit to the ice box.Purchased a Nova Cool unit ,the freezer unit fit perfectly in the upper section of ice box,installed compressor under galley sink area toward the outboard side of compartment,ran refregeration lines from ice box to compressor in back of stove.To reduce cable run hard wired to battery with circuit breaker/switch inside cabinet door under sink.The system came recharged with refrigerant actual install tme was about 3 hours (about 2 days planing)Hope this helps.PS the Nova Cool has worked great over the past 6 years,more than enough capacity so much so that if you set thermostat too high it will freeze everything solid
