Jim-
I found this paragraph from the owners manual for Dometic Tundra Refrigerators and Freezers, although it sounds like it was written for AC units, and I think it has been placed in the Refrigerator./Freezer manuals to warn of water released when defrosting the refrigerator.
"CONDENSATE - All cooling units produce water condensate when operating on the cooling cycle. This water must be
drained from the cooling unit overboard. If condensate is allowed to drip on a wooden structure, rotting or decay and
structural failure may occur which could result in loss of life. If condensate is allowed to drip on electrical components,
deterioration of the electrical components could result in hazardous conditions. When an air conditioning system is in
operation, condensate drains may be subjected to negative pressure. Always locate condensate drains as far as
possible from points where engine waste and other dangerous gases are exhausted so no such dangerous gases can be
drawn into the condensate drains."
From page 12 of
"L-0938: Refrigerators/Freezers Installation/Operation Manual"
The Dometic home page is
Dometic Marine Refrigerators
Now some common sense:
The refrigerator should condense water on the coldest part, the coils/box around the freezer inside the refrigerator. Since the refrigerator has no automatic defrost cycle, your condensate water should be trapped on the inner and outer walls of this box until you turn off the power and manually defrost the refrigerator. (The part of the refrigerator below and or behind or underneath the refrigerator's food containing main structure is the compressor and heat releasing coils, which will not attract or hold moisture.)
I don't see any mention or diagram of a drain in any of the owner's or installation manuals. Do you see a drain hole in the bottom of the refrigerator?
You could email or phone the company representative listed on the Homepage for a definitive answer.
