Hello all. Long time no see.
Yesterday I installed a brand new Flagship Marine 18,000btu lowboy AC in the master stateroom. I used my existing pump which was a "Sea Choice," or the like, 500gph pump. I have no idea how old it was, the previous owner installed it.
After the install, everything worked. It cooled greatly. We started running it around 4pm yesterday, and at midnight it had froze over.
Using what y'all taught me, the first thing I looked at was my pump. I took it apart and although the magnet wasn't broken, there was some play in the impeller. I also thought it may have been undersized. So we went to "bend me over west marine" and paid $390 for a 1000gph Dometic pump.
I just got it installed, everything is working, I've got tremendous water flow, and its been on for about 30 minutes.
The bottom two coils that run through the fins have already exhibited signs of light frost. All the others above it are frostless.
Is this normal to have a bit of frost on the coils through the fins?
I was concerned about the amount of space between the AC and the bulkhead, so to make sure it got enough air I removed a piece of board that was installed for sound proofing . Just behind the red arrow in the photo below is a 18" wide return.
The only other issue that I have a concern about is the drain. The condensate drain is staying pretty full because the drain hole isn't at the bottom of the pan.
What else should I look at?
