To all new BC1206 buyers:
I was concerned that I heard liquid sounds in my evaporator (inside the refrigerator). Sanyo support was very thin, and essentially said that any noises it made were normal.
Beverage Factory was very accommodating, and offered an in place swap out with free shipping. The new unit is here and making the gentle hiss one expects from the evaporator of a small cooler.
A 'water trickling down a drain' sound coming from a evaporator is a sign of an over serviced system. Over serviced freon systems can seem to perform, but if that fluid is able to get back to the compressor then you have a failure waiting to happen.
Thanks to Beverage Factory for taking the matter seriously, heads up to anyone about to get a new unit. Like all other small refrigerators, you do indeed want to hear a very slight hiss from the inside of the box when the compressor is running.
