theOrca Posted July 12 Share Posted July 12 It never fails to amaze me how far out in front of Oliver corporate we owners are. I inquired of HWY RV in Salem Oregon as to the install of a Dometic Fresh Jet 3 to replace the Penguin II noise generator in my hull number 615. They messaged Jason E, and he advised them that "as we have not installed a Fresh Jet 3, we advise caution as the fit might not support the unit properly." That is a very reasonable decision, and stopped me from proceeding. However, in searching the Forums it appears that at least three of us have switched out the A/C and no one mentioned any problems. Lack of reporting is not "data," so I have asked Dometic to provide me with footprint and bolt pattern drawings of both the Penguin II and Fresh Jet 3. Will they do it? I guess that depends on the attitude and enthusiasm of the person at Dometic who gets my email. I sure hope they do as I am very leery of proceeding when "not 100% sure." Could someone who HAS switched a Penguin II for a FreshJet 3 please comment on footprint and bolt pattern? (Please!) In summary, so far I have not found actual data as to the direct comparison of any of the three units mentioned. If and when I get actual data, I will append it to this topic. I can say that I really liked the attitude and professionalism of the service folks at HWY RV in Salem, Oregon. If my replacement project becomes a go, you can be sure that they will be the folks that do the work. 2 theOrca, 2020 Legacy Elite II, Twin, Hull 615 Tow Vehicle - 2016 Ram 1500, Hemi, 8 Speed with 1500# rear springs and Goodyear bags.

jd1923 Posted July 12 Share Posted July 12 They should all fit the 14x14 opening. It's more so re thermostat change and how the condensate drips. Truma requires a special fiberglass build. Personally, I've had enough of Dometic, with the noisy Penguin in the Oliver and another Dometic where the fan lost alignment, shifted and jammed beyond repair in the Bigfoot we had. Anything but Dometic for me. @Geronimo John and several others have installed Houghton models, many threads here. @rideadeuce has scheduled a professional install of the Atmos 4.4 next week and I'm sure Mike will post info on that. I'm looking forward for this feedback compared to cited Houghton issues. Both of these models run the fan continuously which is something I will NOT live with. Known issues are humidity, not an issue for our climate, but I'm not sleeping with a fan running all night. Houghton has cycling issues, without moving the thermistor or something, not cool. There is a relay fix for the Houghton fan and if we go Atmos, I will figure out a relay fix, or hopefully somebody online does so first. The Atmos switches automatically from cooling to heat pump and can do so at dawn when it gets colder. I cannot get confirmation whether there are two set temps, for cooling vs. heat. Again, not cool. Is there a manufacture out there that understands these issues, who makes a better design? 1 Chris & John in Prescott, AZ | 2016 EII #113 | '01 Ram 2500 Cummins!

Footprint equates to where and how much support the roof provides the upper unit. You do not want unsupported weight when fiberglass is being stressed by having that weight transferred to it by leverage. It is desirable to have the entire floor pan of the upper unit supported by the roof. Bolt pattern is always "outside" of the 14x14 opening, and is sometimes very different between brands. These are subjects which require "data" to resolve. 3 theOrca, 2020 Legacy Elite II, Twin, Hull 615 Tow Vehicle - 2016 Ram 1500, Hemi, 8 Speed with 1500# rear springs and Goodyear bags.

rangered Posted July 12 Share Posted July 12 theOrca, The Dometic FreshJet comes with a very nice factory seal where it makes contact with the Oliver. It also comes with four additional factory installed blocks at each corner that help distribute the weight of the unit over a larger area. In addition the FreshJet weighs less than the Penguin. The bolt pattern is inside of the opening, the same as the old noisy Penguin. I hope this answers some of your concerns, you are welcome to message me if you have any questions about my AC installation. 3 4 Alan & Judy Strawberry Plains, TN 2021 Oliver Elite II Hull 759 2023 F250 STX 6.8L Gas Link to comment Share on other sites More sharing options...

This is the issue. For example, at home we program our thermostat for summer A/C temps between 78 degrees in the heat of the afternoons and much cooler to 74 overnight to keep some air movement and sleep better. For winter heat, the numbers are much lower; down to 64 degrees prior to dawn and up to 70 in the evenings. This makes us comfortable at home. The last thing I want in the Oliver, or anywhere else for that matter, is for when it gets naturally cooler overnight approaching dawn is for the heat pump to come on when the temp gets 1-2 degrees lower, OMG! A valid design has at least two set temps, one for each system (at home we have 4 per day for A/C and 4 more for heat). Why do these design engineers not understand something so basic. When I talked to Kevin at SDG, the Atmos rep and installation co., he explained it in this way. I asked him, why would I want that? He explained it as a positive feature, and I replied that to me this is an issue. I would rather the A/C not have heat pump, or at least the ability to turn it off. We use the ceiling A/C when it's hot, run the LP furnace when it/s cold and I have NEVER seen a 24-hour period where we want or need both. 2 Chris & John in Prescott, AZ | 2016 EII #113 | '01 Ram 2500 Cummins!

I would think that install has been completed by now, but no subsequent report to date. Me too. My install is coming up on Wednesday. The first Atmos 4.4 bought for an Oliver was returned before install because it was the color black and the owner decided to wait on the white version to become available. At least, this is what was told to me by Kevin at SDG. The manual shows it has an AUTO MODE. You should be able to pick AC or Heat or AUTO and set corresponding temps. The unit does not receive heat signals when in cool mode only. If you can only pick a single temperature in AUTO MODE... that would be a bummer and I will be unhappy as well. At that point, I would just use the separate HEAT ONLY and COOL ONLY modes. It also has a timer OFF FXN and dehumidifier mode. The heat pump is very nice thing to have IMO and can easily be turned off. Since the unit is quiet, I actually like the idea of the fan running to circulate the air until I turn the unit off or set the timer to turn off. The APP is the only thing I can't find much information on but ratings are good. For sure, I will let y'all know how the ride home from MI to TN goes!

Ronbrink Posted July 14 Share Posted July 14 @rideadeuce, thanks for the update on the other owner’s status. In one of the videos viewed, it was stated that a temp could be set and cold/heat would maintain it. There has been some misinformation given before that proved not to be true or at least not fully understood/conveyed. Good luck with the install. SDG has done a good job on video taping various installs, any chance your Oliver install will be similarly documented? 2 2020 OLEll, Twin, 579 2012 Silverado 1500 4x4 No installed solar, Renogy 40A DC-DC charger, 460Ah LFP battery bank/Victron SmartShunt, Hughes Autoformer, dual Lagun tables Link to comment Share on other sites More sharing options...

Reading this makes more sense. Not sure when I questioned Kevin, he didn't inform me that I could use COOL vs. AUTO modes for what I asked. The fan will still run all night. My fix for that is the timer or the remote would be in arms reach, powered off when needed. Now that I have the furnace duct mod, with bedside duct capped off, I believe I would likely rarely use the heat pump which would blow warm air over the beds and not front or in the bathroom. Many voice they like the heat pump option. I'd give it a try to see but would likely prefer the warm bathroom and heat aimed on the floor vs. up in our face. For those of us who camp more often on inverter than connected to shore power, when A/C the sun is out and there is some positive AH offset. When you need heat, most of the time it's dark outside using considerable AH without solar replenishment and we carry 60 gallons of efficient LP. 1 Chris & John in Prescott, AZ | 2016 EII #113 | '01 Ram 2500 Cummins!

I am having mine installed at Highway Trailer Sales in Salem, Oregon next week. Everything is in their hands except for the needed extra roof seal that lets the condensate drains flow through the Olly drain. Despite it appearing in a Dometic advertisement, they have NOT produced a Fresh Jet 3 "non manual" ADB. I think their universal ADB woulld be a bad idea since it was not designed specifically for the Fresh Jet 3. I would have liked to have had a non-manual ADB so that I could use the Olly thermostat. I went with the ADB with manual controls. I guess I can always change out the ADB if Dometic ever gets around to actually producing a Non-manual Fresh Jet 3 version. I will post again after the install... 2 theOrca, 2020 Legacy Elite II, Twin, Hull 615 Tow Vehicle - 2016 Ram 1500, Hemi, 8 Speed with 1500# rear springs and Goodyear bags.

There are 2 others who did install it and posted on the forum a year or so ago. Curious about the drain condensate location and the extra roof seal you mention and the thermostat. My Penguin has heat strips and the Fresh Jet does not. I was told by a dealer the harness plug at the unit was the same but because of the heat, the thermostat might now work. When you post after install can you mention what thermostat you have and if your Penguin had heat. Also what is ADB?
