Sorry about missing this post. Get a %RH meter and measure the air in and out of your dehu. Catch the mositure of the dehu in 30 mins. How many sqft. of space?
We can tell how it is working. Basement should not smell musty with any good dehumidifier.

Bear Rules: Keep our home <50% RH summer, controls mites/mold and very comfortable.
Provide 60-100 cfm of fresh air when occupied to purge indoor pollutants and keep window dry during cold weather. T-stat setup/setback +8 hrs. saves energy
Use +Merv 10 air filter. -Don't forget the "Golden Rule"
