Attached are pictures of the "diverter mod". This mod will eliminate your quick cool dump vents on the chill grill. Air will only flow through your ducts to the outlets. I added an outlet in my bunk house which doubled the air supply volume to that room. After doing this mod construction debris started to fly out of the rear and forward vents which told me I did something right. Your current setup dumps air stright down at a plate and forces it out to the ducts rather than guide it to them. By guiding you are achieving more volume to the rear most vents and more efficient. I had my unit running 24/7 for 20 days in high humidity and hot temps without any freeze up or issues. The unit would run a lot but shut down a few times when it reached temp.
Of note I did fully enclose the ramp with metal tape and taped it into the opening before re-attaching the chill grill. All sides where foam was protruding I trimmed and taped over for smoother airflow. I then sealed it shut with the tape so all my airflow is now 100% ducted with no leaks or major turbulance.
It's a cheap fix to an inefficient system that does help. Adding a duct where you have more sq ft to cool will help too. They can always be closed.
