Advent Air Accessories and Parts - ACMSCKIT

  • RV Air Conditioners
  • Start Capacitor
  • Advent Air

If your generator or shore power needs a little extra help to start your RV AC unit, this start capacitor will give it the power boost it needs. Relay switch turns the capacitor off once power has been supplied.


Features:

  • Start capacitor jumpstarts the AC (sold separately) when a campsite or generator doesn't provide enough power
    • Stores energy that will later be used for the next startup
  • Relay switch turns starts capacitor off once sufficient power has been supplied
  • Easy, bolt-on installation with the included hardware


Specs:

  • Overall dimensions: dimensions: 2-1/8" long x 3-5/8" deep x 6-5/16" tall
  • 1-Year warranty


How the Start Capacitor Works

If your campsite or generator isn't able to draw the power you need, then you may have difficulty starting your AC unit. The included start capacitor, however, can eliminate this problem. The capacitor stores energy that will later be used to jumpstart the AC. Once the sufficient amount of power has been supplied to the AC, the compressor will start to run, and the internal relay switch will turn the start capacitor off. At the same time, the compressor will send "back voltage" to the relay switch and capacitor in order to energize them for the next startup.


Simple Installation

To install, bolt it to the fan motor support with the included hardware and then route the wires to the run capacitor.

by:

Hard start capacitor kit istalled in 5 minutes and works perfectly to keep the Advent AC cooling and never popping the 15A breaker, like happened regularly since install of the Advent. etrailer come through again!



by:

Works as advertised. Originally was told that this part wouldn't ship for over two months, I ordered it as a bundle with new rooftop ac unit, however it arrived same day with the new ac unit! Easy install and helping to cool my RV!



by:

Relatively easy to install. Putting each connectors on the right pin was a little confusing, but worked out ok. Fast shipping. Very satisfied. Working with Lance was very pleasant.



by:

Amy, I want to thank you for your help in me being able to install my Camper's AC. Once I got the harness you advised me to get I was able to hook it up. It works great. I received the Capacitor on Saturday I installed that yesterday. It works perfectly on 120v. I have one more test for it when I hook up to my generator's on Thursday when I'll be camping. I'm sure it will be just find. Thank you again. It's a pleasure doing business with you.
Respectfully;



by:

my order left etrailer within an hour of being placed. it arrived freight free 3 days later via ups. the ac was packaged very well and arrived without any visible damage. it is compatible with original thermostat and ceiling control box from a 2003 dometic 15000 btu duo therm . had to make a minor adjustment to the partition between the air chambers.the original ceiling plate was reusable as well.



by:

Received after delivery of the roof AC unit,but well before the initial backorder date. Thanks Will ... great to work with



by:

Simple to install, good instructions with pictures, works great!



by:

Easy install. One wire to red wire terminal & the other one to the middle terminal of the capacitor. Done.



by:

This was an easy installation, thanks to the etrailer vidio.



by:

It only makes sense to install this extra capacitor to your RV air conditioner. This unit arrived with easy to follow printed instructions and the video instructions were a great help. Installation only took a few minutes.
***One tip I would offer when attaching the capacitor to the blower - screw in the attachement screws first without the capacitor. The screws are a tight fit intially and this step will allow them to go in much easier when you are attaching the capacitor body.

As always etrailer has the right products at the right price with excellent customer service.

Great no Problems!!



by:

Our AC starts good on 20 amp circuit using this start capacitor



by:

Installation went well and the instructions was easy to read and understand.I had the old unit out ,cleansed the roof and installed the new unit by myself in half a day and finished up wiring inside in a short time .Everything worked as explained,Thanks so much for your input and help with picking the right replacement ac unit



by:

Very fast delivery time. Excellent packaging to help prevent damage during shipment. Haven't installed parts yet but everything looks good.



by:

The item was delivered on time and very very easy to install I had it done and I would say less than 5 minutes between removing the cover routing the wires over to the capacitor and making the connection everything that was needed was included would recommend buying. I'm using a 3500 run time generator at my camper to operate a 15,000 BTU air conditioner and I wanted every Edge to help the compressor start without bogging down the generator I haven't done the actual run yet but I'm sure it will be okay and do as it was meant to do I've noticed Improvement with the startup of the air conditioner even under normal conditions plugged into Shoreline.



by:

Easy install no problems. Arrived and package well.



by:

This is a must have for using the advent air 15kBTU with a generator. Great product, very easy installation, very easy wiring.



by:

Easy install, but I couldn’t tell you if it works, as I never ran the unit without it.



by:

Very easy to install. The included instructions were very helpful.



by:

Exactly as advertised, installed myself. If you aren't doing business with etrailer, you get what you deserve.



by:

Not sure if I needed it, but I added it with my new ac because the old one had one. It was the simplest install. You may as well do it and not worry about hard starts.



by:

Installed this start capacitor on my new Advent RV air conditioner that replaced an old Carrier Air V unit that I had installed a soft start on. This start capacitor was only $19 dollars compared to $300 for the Soft start.

  • Complete AC System With An Advent 13.5K BTU Low Profile AC Unit
    Hello Tim. We can definitely set you up with a complete AC system with an Advent low profile unit. We currently do not offer these parts as a package, but you can purchase all of the exact same components separately. To answer your question, yes, the same air handler will work with the low-profile unit. Here is what you will need for the complete AC system: - Advent Air Low Profile RV Air Conditioner - 13,500 Btu - White # ADV79FR - Air Distribution Box w/ Built-In Thermostat for Advent...

  • What Is The Smallest AC Unit For Adding AC System To A Cargo Trailer/Camper
    Hello Tyson. The smallest AC unit we offer is the Advent Air Low Profile RV Air Conditioner and this will be a great option for you. Since this is a smaller trailer you can definitely get away with a 13,500 BTU unit. These AC units require the roof to be between 2-1/2" and 5" thick, so please do keep that in mind during your build. For a complete AC system I recommend the following: - Advent Air Low Profile RV Air Conditioner - 13,500 Btu - White # ADV79FR - Air Distribution Box w/ Built-In...

  • Recommended Replacement for Dometic 15K BTU Rooftop RV Air Conditioner
    In order to replace a Dometic Rooftop RV Air Conditioner I recommend using the Advent Air RV Air Conditioner, part # ACM150B for black or part # ACM150 for white. These are excellent replacement options which offer a direct fit. It comes with a two year warranty as well. Please note, if you use your generator to power the air conditioner then you'll want to consider a start capacitor like the Start Capacitor for Advent Air RV Air Conditioners part # ACMSCKIT which cuts down on power demands.

  • What Distribution Box Is Required When Installing The Advent Low Profile AC In a New Opening?
    As you are adding the Advent Air Low Profile RV Air Conditioner # ADV89FR to an opening on your RV which did not already have an AC you will need to select from one of the 2 options. First is the manually controlled Air Distribution Box # ACDB. This has the manual dial you will switch on and off as needed. The other option is the Air Distribution Box w/ Wall-Mounted Thermostat # ACRG15. This is typically more convenient and necessary on taller campers where you cannot easily reach the ceiling...

  • Will An Advent Air RV Air Conditioner Be A Good Replacement For A Dometic Unit
    The Advent Air RV Air Conditioner # ACM150 has an approximate decibel level of 76, which can be a bit loud since anything over 70 is typically seen as a disturbance. If you have a ducted system closing the vent on the plenum of your air distribution box and solely using the ducts can help cut down on noise. The Advent Air # ACM150 doesn't come with a soft start, but you can purchase one separately with part # ACMSCKIT. Adding on a start capacitor can also help reduce the decibel level...

  • Recommended Replacement For A 13.5K GE RV AC Unit
    We recommend the Advent Air RV Air Conditioner # ACM135 to replace the GE 13.5K RV AC unit. The advent unit has the same 13.5K BTU rating. You will also need a new distribution box and/or thermostat. You can use # ACDB for manual control or the # ACRG15 which comes with a wall mounted thermostat. Advent sells their start capacitor # ACMSCKIT separately, and we do recommend picking up one of those as well. You also have the option of adding a heat strip # ACMHD.

    For a replacement I recommend the Advent Air RV Air Conditioner w/ Air Distribution Box and Wall Thermostat # ADV94FR. This has everything you need, including a digital thermostat, for a complete replacement. The system has a 13,500 Btu capacity and comes with a 2-year warranty. If you would like an electric heat pump the # ACMHD can be added on. You also have the option of adding the start capacitor # ACMSCKIT for a power boost if enough power isn't available from your generator or campsite.

  • Recommendations For Adding AC To A 14 X 8 Enclosed Trailer
    We can definitely help set you up. For a 14' x 8' enclosed trailer, I believe a 13,500 BTU unit would be sufficient. I recommend the Advent Air # ACM135. Advent makes a solid AC unit, which will fit perfectly in the 14" hatch on the roof. Keep in mind the roof does need to be between 2-1/2" and 5" thick in order to install this unit. As far as your controls, you have two options. You can either use a manual distribution box # ACDB, which will put your controls on the ceiling right above...

  • Replacement Air Conditioner for Horse Trailer Living Quarters
    Since you currently have a ducted system I recommend the Advent Air RV Air Conditioner - 13,500 Btu # ACM135. This will work with Dometic (Brisk I or Brisk II), Coleman Mach, or Carrier setups. If you currently have a Coleman with a 9-pin connector you will need adapter # ACCOLKIT and if you have a Carrier # ACCARKIT. If you wish to add a start capacitor # ACMSCKIT or heat strip # ACMHD they are available separately.

  • Replacement Air Conditioner For Dometic Brisk II on a 2015 Forest River Wildwood 286RLT 5TH Wheel
    You can replace your Dometic air conditioner on your 2015 Forest River Wildwood Heritage Glen 286RLT 5th wheel with the Advent Air RV Air Conditioner # ACM150B. This will allow you to use your Dometic thermostat. I recommend adding the Start Capacitor # ACMSCKIT to reduce the draw load on your electrical system when starting the AC.

    The SoftStartRV Soft Start for RV AC Units # SSR54FR is designed to work with single-phase air conditioner units. If you remove the shroud there's a tag on the compressor that should state if your unit is single-phase or three-phase. If you have an Advent Air unit then you'll want the Start Capacitor for Advent Air RV Air Conditioners # ACMSCKIT instead. If you were replacing the start capacitor on a Furrion unit you would want the # FR45FR for a 14,500 BTU unit and the # FR65FR for...

  • Replacement For Dometic Duo-Therm Quick Cool RV Air Conditioner
    Hello Cherry. To replace your Dometic Duo-Therm Quick Cool AC Unit I recommend the Advent Air # ACM150. This is made to be directly compatible with your existing Dometic AC system. You'll just need to remove the cover to your air distribution box so that you can get to the mounting bolts and wiring. Aside from you can basically just swap out the rooftop portion and leave the rest of the AC system as-is. I do suggest that you pick up a Start Capacitor # ACMSCKIT. You also have the option...

  • Recommended Replacement Option For Dometic Duo-Therm AC On A 2008 Gulf Stream Tour Master Motorhome
    If you're replacing the controller you would want to replace the entire system. Your system's rooftop unit hasn't been confirmed to work with a different controller and with yours not having a 6 or 9-pin connector you'd have no way of connecting it to a new controller. For this I recommend the Advent Air RV Air Conditioner System # ADV64FR so that you can have a digital wall thermostat. I do recommend also picking up the start capacitor # ACMSCKIT to help lower the starting wattage needed...

The Advent Air RV Air Conditioner # ACM150 you found is only the rooftop AC unit and would need the Kit # ACMSCKIT as well.

  • Parts Needed For A Complete Advent Air Low Profile Air Conditioner System
    Hey Chad, You'll need an air distribution box to go with your rooftop unit # ADV79FR to get the other half of the system. You could go with the # ACDB if you want the controls built into the air distribution box or the # ACRG15 if you'd prefer a wall mounted thermostat. If you go with the wall mounted thermostat then you'll also need to pick up some wiring to run from the thermostat to controller built into the air distribution box. While not necessary it is recommended to also install...

The Advent Air RV Air Conditioner, # ACM135B that you linked to is a 13,500 Btu and designed to be a cost effective direct replacement for the Coleman AC units. It will install using the Coleman Mach Adapter Wiring Kit for Advent Air RV Air Conditioners, # ACCOLKIT.

  • Is There A Heat Strip Available For An Advent Air RV Air Conditioner System
    Yes, you're looking for the Advent Air Heat Strip # ACMHD to go along with your # ACM150. This system requires a 14-1/4" long x 14-1/4" wide roof opening, which is pretty typical for all RV air conditioner systems. I highly recommend getting the start capacitor # ACMSCKIT as well to cut down on the power surge every time your unit starts up.

    The Advent Air Replacement RV Air Conditioner for Dometic Setup w/ Start Capacitor # ACDOM150 comes with a wiring harness adapter to make installation a simply plug-and-play with your current Dometic system.

  • How Many Amps Does Advent Air RV Air Conditioner ACM150 Use?
    I am not quite sure where you're seeing 30 amps for the Advent Air # ACM150, but it has a total amp draw of 15 amps when running, with 12.4 amps being the compressor and the remaining 2.6 amps being the fan motor. This will be just fine at replacing your Duo Therm 13.5k BTU, and the wiring will be more than adequate for this power. The only time the amps will be really different is with startup. It's not a bad idea to install a start capacitor like # ACMSCKIT if you're going to be powering...
