Issues that I've found and a few solutions. 1. Size naturally makes it vulnerable to clogged sponge filter, which causes a slurping sound. Cleaning and regular maintenance helps prevent this. Don't clean your indoor coils while letting it drain into pump, also have found pan tablets clogs spnge filter. Keep extra filters on you. 2. Lack of required maintenance ( which could be way more often than people realize) can lead to a dirty water (float) sensor and unit will keep running. Everytime this has happened cleaning it has only fixed it once. The other times it just kept pumping regardless of cleaning. 3. Anti-Siphon valve ( lil green thing on yellow tube) is not made for length we think it can accommodate (Also it drips water a little but it doesnt seem to be an issue). This leads to slurping and sucking after pump has stopped. At first i thought it was a dirty filter, then dirty water sensor continuing pump after empty. Then realized there was a siphoning effect pulling water thru pump after it disengaged. I later found out, thru refco's competent tech support, that the pump tubing was ran too far vertically after too long horizontally. Basically cut downflow part of tube as short as possible to reduce siphoning effect. It worked. Would like to add, competent is a a huge compliment when i think of tech support. 4. Obviously make sure drain line doesn't sit flat against bottom, either cut at slant or notch it. All in all this lil pump opens up options as it has a very powerful pump for its size and it looks good. But always gravity drain if possible Hope this helps
They are super quiet, except in my case I have some squeaking and squawking going on from an apparent vacuum issue. Line goes up into ceiling with a 10 ft horizontal run before it drains. Would like to see a comparison between this and the Combi unit they have. What I see happening if the power goes out, that line continues to drain and overflow that little tray. Mine continues to drip for like an hour before it stops. Just wondering if that’s an issue with the way the Combi is installed instead. Look forward to your response.

is it still quieter if the condenser is above the split duct?
Have you ever taken the cover off one of these once it’s mounted? I can’t get that thing off.
Too much stock in graphic me to see how you wire the unit
super quiet !
