Originally purchased my Frigidare dehumidifier and the instructions stated to run continously the first several days. Did that and had to empty the 30 pint (may be the 50 pint model) container within three days. Probably needed it in two but I was not there. After that I set it to 50 which I found that it did not run all the time. By the way its a 31ft TT. Since then I set it to 35 and I have noticed it still does not run all the time which is good.
You can definetly notice the difference inside the trailer. I do not want mine to run all the time but I do want it to keep dry. Need to find what a good humidty level is.
