The directions in my kit did not tell me where to mount the sensor on the cooling fins. Is your sensor on the right, near the flue, or the left?
The sensor is connected to a fin all the way on the right. I spent a good part of the day on line researching this whole deal. Dometic has a pdf on line which details ventilation on the various refers depending on the set-up. (roof vent or refer in the slide) I have a 2862 in my 320rs. Dometic only lists a 2852. Took me a few minutes to figure out that the 2862 has the adjustable thermostat while the 2852 does not. So, looking at the pdf about the ventilation requirements, I discovered that this refer was installed with a fan because of the 2 side vents and no roof vent. I have not heard the fan work but I assume that it does. The pdf also shows baffles etc. They show a curved baffle at the top of the chimney that would serve 2 purposes. The first being that the baffle would direct any air being pushed up by the fan out the top vent. The second purpose would be to close off the dead space above the refer which without the baffle would just collect hot air. I went to my trailer this afternoon and pulled both the top and bottom vent. Everything looked OK on the bottom. When I pulled the top vent, I discovered that the curved baffle that was supposed to be there to direct the air out and close off the dead space was missing in action!! The factory was nice enough to line the dead space with insulation, I guess to keep the heat from the refer from entering the trailer. It would appear that the factory did not bother to read the whole installation sheet. I am disappointed. I will add the curved baffle and I am betting the performance of the unit will inprove with what will now be a proper install. Those of you who have the 320rs, I would check behind that upper vent. Maybe they just forgot mine, but I would not bet on that.
