1) Keep these lines clean by adding a water/bleach solution to the pan every 6 (?) months.
2) Plugged lines can be blown out with a simple bike pump w/ nozzle.
3) I've had fewer problems with the Aspen Maxi Orange than the Refco Sahara brand.
I'm not in love with the way these units drain into the sump but have no better design.

Beneteau could use a lesson in routing drain and vent lines. I spent a day re-configuring my water tank lines because they had low points accumulating water and blocking venting along with unnecessary twists and turns. I have never had a boat before that had to have mini sump pumps for HVAC draining. I still haven't worked out all the re-routing around the sump box as the HVAC manifold angle needs to be adjusted and some other lines there.
I have always been advised against using bleach. Someone recommended dropping something into the pan occasionally but cannot remember what it is called now but it was maybe something "pan tablet". I open the mini sumps when I clean the air filters and clean them out. The metal screens have already had to be replaced. When I winterized, I added antifreeze directly into them. I do not like the Orange Minis, they are loud, and wake up people sleeping with a buzzing sound. I am planning to have them swapped next year. I am hoping to try the Orange Maxi.
Other maintenance I now do is Barnacle Buster through the raw water system on the HVAC. I posted in the other thread with how I did that. I plan to do it every other year as of right now.
