I spoke to Mary, at Newmar Service. She confirmed that Newmar is installing Coleman products now. She also confirmed that last of the 15K Heat Pump Dometics are gone.
I think it was a pretty smart thing on their part. I'm in some part surprised by Dometics approach to this. Right now --- they have no Low Profile 15K units to offer. And the 15K A/C unit I purchased...has no documentation. (Other than a file I can find about the Air Distribution Box...which Newmar's do not use).
Anyway --- I used my network tester. The RJ11 wiring in our coach, I now understand. There are four runs on our 2 A/C coach. Thermostat to A/C Front. A/C Front to A/C Rear, A/C rear to AGS command Controller in basement. Which is exactly like the old installation guide for the Penguin II laid out.
I installed our Freshjet 5 yesterday... It comes with no control board. It has only the housing, the evaporator, condenser, compressor, capacitors and ptcr, the fan unit, and wiring for those items...which all go thru the box where our controller is normally housed and to a 6-pin molex. What to do? Well you have to purchase a separate controller that is like the one in the basement. It comes in a metal box with connectors all around the perimeter. One accepts the 6-pin from the rooftop unit. And you plug in the 6-pin DC/Furnace plug from the coach, the remote cabin temp, the two RJ11 comm plugs, the outdoor temp sensor, freeze sensor, and power from the Molex Power kit... And then have to figure out a good place to mount that. I have seen these installed inside the Air Distribution Box on other Rv's. We don't have that luxury. So, rewired the unit using the parts I scavenged from my Penguin II. The new unit has a metal housing on the compressor side of the unit with the two capacitors and PTCR. I would have left it there...but didn't want to cut into my Easy Start bundle to pull a wire out...in retrospect it would have saved me some time... I threw out the start capacitor and ptcr and moved the RUN capacitor over to the control box housing...where it is on the Penguin II. It's all the same wiring, save the fact there is no Reversing valve in a Non- heat pump unit.
Why am I telling you this?
Be careful buying a Freshjet 5 if your installer doesn't have experience installing it in a Newmar. He may do it fast...and find a place to put the added control box...or charge you a number of added hours to rewire it to use the original controller.
The only difference I see between the two...is the stand alone has a molex connector for a heat strip. The board we have in the Penguins is setup for a reversing valve... I haven't looked into it...but the same pins might do the heat strip function...I'm not sure about that. I'm not bothering with a heat strip anyway.
Anyway... The mounting holes are on a little mound...so water wont' pool by the lag screw head... So, I need to source slightly longer lag screws...and and I need to put some butyl tape under the foam pad where the screws go in...to insure a better seal. Not sure what the lag screws are drilled into down there...but it doesn't seem like I'm getting good purchase on anything. Except for one longer lag screw used by Land Yachts when they replaced my unit in 2020.
I'd use 3m 5200 if I thought the air conditioner would last my lifetime. But these things are not built to last.
I need to check with a magnet...but it looks like the Internet rail they place in floor is aluminum vs powder coated steel. I have an original unit on the back...and it's steel...and rusting out. So, if this is aluminum...it might actually not rust out.
Anyway...going to take a day off...and then find some new lag screws and butyl tape to secure the unit better...
