Last year Sea Frost offered me a system, with the BD80. I was having trouble finding a new electronic control unit for the BD3f compressor, but eventually found one. Sea Frost normally ships pre charged with R-134 and special disconnects, but my system was installed at boat build with plain connectors. My system is set up with automobile A/C style test fittings and a sight glass on the receiver/dryer. I bought a $29 set of Harbor Freight gauges and can add R-134 from the 12 ounce cans available at Wal-Mart. The boat came to me used from Moorings Charters with the fridge barely working. Sea Frost and Kollmann talked me through the evacuation, recharge and adjustment. One complaint: I cannot get the expansion valve totally insulated/sealed from air. It sweats and drips water, it should be mounted inside the fridge instead of outside.
