Thank you Chuck. I have been talking with Jeff about this, our bedroom fan is also making noise and I will be replacing it. I do have access from two sides and hope to be able to replace the fan without removing the unit. If I do need to remove it, knowing the pan is attached is good information to have.

I have the middle unit fully ducted and working. I went through a couple design iterations and ended up making some custom ducts for what I think is optimal air flow.
The original supply ducting, made of rigid board insulation, came right out of the unit and had the air go straight down, then two sharp 90 degree turns into ducting that gets directed to forward and behind the unit to front and rear of the coach (ducting actually goes through entire coach and connects to the other two units, and also has smaller outlets on the ceiling nicely concealed by other ceiling panels). This primary outlet duct continues downward, having the air slam straight into the ceiling panel, and the air makes a hard 90 degree turn to go out the front and rear of this local ceiling panel. I suspected some of the noise was due to how poorly the air flow is directed. Also, the ducting that provides airflow to other parts of the coach IMO never worked well or perhaps not even at all due to the duct design.
I sought to change this by having as gentle as possible transitions of the airflow direction to these ducts. I decided to make most of the ducting with rigid insulation panel, much like the previous ones, but I would make curved walls by kerf-cutting the material and bending and gluing to the radius I need.
Some transitions were done with metal ducting material where the thickness of the rigid foam was too thick or manipulating that material would not be practical.
A bottom panel with two quarter circles joined direct the air to the local outlets on the local ceiling panel.
The original electrical junction box was removed, as it was tucked up there and very hard to access. Two new boxes were added with the access panel facing downward for easy access. One box contains the high voltage wiring and the other the low voltage.
I forgot to measure the sounds level with the Dometic unit, but it was quite loud. In the bedroom, it was so loud that you would have to crank the TV volume to hear anything, and then when it shut off, you’d want to turn down the volume because it was so obnoxiously loud, and I’d end up repeating this process over and over as the A/C cycled on/off. This unit ranges from 32 – 40 dB depending on the fan level. I would say typically it’s going to be 35 or less.
The ducting that connects all the units also seems to work a lot better. With just the middle unit running, I get decent air flow to the very front and rear of the coach. Probably not enough to cool or heat (now that these are hat pumps) the coach with just one unit during temperature extremes, but if all you are needing is 10F cooler/warmer inside that outside, the middle unit ought to cool/warm the entire coach down within ~2 degrees.

Thanks Mikee
Will add that to the to do list. Dealing with removing and rebuilding various hydraulic rams on the slide outs right now.

Got into a Conversation with a retired army mechanic about series 60 future parts availability. He told me the military used a lot of 60 series over the years for various applications and plenty are still in service. He felt parts availability would not be an issue for years to come.

Hi Dick:
Sanded with a palm sander for two reasons. 1 Had some clear coat peeling that needed the ruff edges smoothed. 2 Just wanted to make sure the surface would accommodate better adhesion. The only problem was the aching bones during and after the project.
Did tape off all edges, antenna mounts, etc. when I started pulling the tape it was like a rubber band and started peeling off the bus-kite. SOLUTION – remove the tape while the bus-kote is still wet or cut the edge below the tape with a razor blade, remove the tape, then using a small paint brush, seal the open edge created by cutting the tape. This is what I did.

I am confused. Previous info I have seen indicates 3 amp fuses are needed on the 12V & 24V positive leads. Have never seen lamps/indicators needing fused.

I can’t find any check valves per se. Solenoid valves yes, but I’ve bypassed those without success so far. One pump on Webasto for that system.
Dick
Yes Webasto pump is running. Works fine if heating interior exchangers – also heats water heaters but only in that scenario.
Thanks BG

The recommended fuses are pretty small: Looks like all 1amp.
Notice the yellow wire.
I’d like to find a fuse panel with lights so I can quickly tell which of the wires is trying to tell me something.

I agree with this philosophy, My main and secondary would hold for weeks.
Then a rash of both tanks being at 0 psi in a matter of a day to main tank holding for a week and the aux tank at 0 psi. I have seen the opposite where the aux was at 120 psi and the main at 0 psi. Different drive, different symptoms, cheers.

Adding to the confusion, I am sitting I’m a rest area with the genetic happily purring along for the hour or so. I hate these intermittent problems!

Yes, on the generator I have the same warm/start switch. The auto start button is not lit but I will check that again. Just can’t figure out why it runs as long as I hold the start toggle switch up.
