Features to know about

Why Use a Soft Start for Your RV?

A soft start device reduces the initial inrush current when an AC compressor kicks on. Instead of that harsh power spike that can trip breakers or overload generators, the soft start gradually ramps up the compressor's motor, making it easier to start an AC unit on limited power sources (like small generators, shore power, or inverters).

Stay Cool Without the Surprises

If you've ever worried your air conditioner would trip the breaker just as you're drifting off to sleep, or have dreaded that loud, clunking start in the middle of the night, this soft start will help you relax. Once you install this device into your FreshJet, your AC compressor starts up quietly and smoothly. Your RV stays comfortable and your sleep stays undisturbed.


More Campsites, More Freedom

You want to stay off-grid, visit state parks, or camp in the mountains, but small generators or limited hookups make running your AC tough. This soft start reduces startup demand by up to 75%, letting you power your FreshJet air conditioner on a smaller generator, at altitude, or alongside your coffee maker, so you can enjoy more places and longer trips without worrying about power limits.

Longer Life for Your AC

It's frustrating to worry about repairs or replacement costs on the road. By smoothing out every start, this soft start limits the strain on your AC's motor and compressor, helping prevent wear and extend the life of your system. And it's designed to resist vibration, flames, dust, and rain. An integrated bypass contactor and start capacitor keep your AC safe, even in tough conditions. So wherever you camp, you get more reliable cooling season after season.

Install Quickly, Troubleshoot Easily

Nobody wants a complicated install, especially when you're ready to hit the road. This controller is pre-wired and mounts right inside your rooftop unit with included hardware. Three built-in LEDs show you status and help diagnose any issues fast, so you spend less time troubleshooting and more time enjoying your adventure.

Video Transcript for Review of Dometic Soft Start FreshJet Mechanical Air Conditioner Setup - DMC87RR

Hi everybody, Andy here with etrailer.com. Let's take a real quick look together at this Dometic soft start for your FreshJet mechanical air conditioner setup. Now this has been designed, as I mentioned, to fit your Dometic FreshJet mechanical air conditioner unit. And this soft starter is going to reduce the power needed to start your Dometic FreshJet air conditioner for a more efficient operation. This has been designed and tested for all RVs and motor homes, and this is going to be perfect for boondocking, supplementing generator power in high altitudes, just to name a few ways that this is gonna be great for you. Now this will let you run your air conditioner on a small generator or simultaneously with small appliances.

You will need one soft start controller per each air conditioner unit, so one per air conditioner unit. So some benefits that this is going to give you is it's going to limit the stress put on the motor, the compressor, and the drivetrain to extend the life of your air conditioner. The built-in start capacitor is going to control the torque to ensure smoother starts and stops. So this is going to eliminate the trailer shaking and loud clunking startup noise from your compressor. You won't be jolted awake in the middle of the night.

And this is going to prevent overheating using an integrated bypass contactor. It resists vibration flames, and this is IP65 rated against dust and low pressure water jet spray. It's probably gonna be difficult for you to see, but there are LED lights here that's gonna show the operation status and alerts, so you're gonna know about potential faults and things like that. This is going to be a pre-wired installation with the included cable ties here and what I'm calling the pigtails here. So this is going to be all included.

So what's nice about this is you're not gonna have to worry about cutting wiring or crimping wires or things like that. This bracket's going to be attached to this. And then let me go ahead and provide some measurements for you just so you have a good idea of the size. So the length that I'm gonna give you is gonna be from end of post to end of post where these cables start to come out. So end of post to end of post, see if I can get this lined up here for you just so you can see.

So as you can see, we're sitting right at about 8 1/4 inches long. And then looking at the width, the bracket's going to make this a little bit wider than the unit itself, we're sitting right about 3 3/4 inches wide. And then the overall height, about five inches tall. And this has a maximum working temperature of 140 degrees Fahrenheit. And this is about two or three pounds, so it's not terribly heavy. Instructions are included to guide you through the installation process. But I think that's gonna wrap up our quick look today. I do hope that it was helpful for you. Again, my name is Andy. Thank you for joining me.

Very good service. I’m an etrailer fan. I’ve bought from them before and will buy from them again.



by:

It's an easy hookup and works excellently.
My
only issue was that there was no instruction but a QR code to get instructions, which was corrupted.
I found a guy on utube, and very easy, but I was not going to destroy a new unit.

You would think the manufacturer could put install instructions in the box for a 300-dollar unit.
