Slides for the CFX3 models

Key upgrades from the CFX line of slides

• Lighter but same strength
• 3” more extension in same footprint
• New release mechanism - a lot more reliable and removes slop when slide is latched
• Dust cover to keep sand out
• Moved mounting holes for easier installation
• Improved packaging to keep the slides in great shape until you install
• Made in USA

Slide for the CFX3 28-35

Slide for the CFX3 55IM

Slide for the CFX3 75-95

Slide for the CFX3 100


Generally all are very similar in design except for the size of the slide and the cooler it matches up with.


Availability
You'll find additional product information and pre-orders open for the slides mid-March 2020.

Note - As of Jan 22, 2020 we still have slides for the CFX series up on our site under the Accessories area.

I'd shared some noise level specs in another thread and thought they'd be useful here as well.

These are the dB levels on all the models in our CFX3 line when they are running:

CFX3 35 44 dB
CFX3 45 47 dB
CFX3 55IM 48 dB
CFX3 75DZ 50 dB
CFX3 95DZ 50 dB
CFX3 100 50 dB

To compare:

60 dB would be a conversation in restaurant, office, background music, or an air conditioning unit at 100 feet.

50 dB would be a quiet suburb, conversation at home or large electrical transformers at 100 feet.

40 dB would be a library, bird calls (44 dB), or the lowest limit of urban ambient sound

30 dB would be a quiet rural area

Over a lot of conversations, we've heard a lot of questions related to fridge use and energy consumption; in particular, how long can you run a fridge without ending up in a "no-start" situation.

There are a lot of factors involved in determining this: type of battery or batteries, condition of the charging system, wiring to the fridge, how often you open the fridge, actual electrical consumption that the fridge requires, etc. While we may not be able to determine the condition of your wiring or charging system, we can help with info on what the CFX3 line of fridges consumes power-wise.



In the above graph, we've measured each of our CFX3 models running at typical fridge (39 degrees F) and freezer temperatures (5 degrees F) and how external ambient temp impacts energy consumption. Given that the hottest temps will be in the day, you can rest assured that power consumption at night will be much lower regardless of what temp you set.

While the above graph will help you decide what CFX3 you might be interested in and how your power system will support, you'll also have access to our updated app. Not only does it help you control and monitoring everything on your cooler, it even tracks power consumption. You'll quickly get a feel of how it works with your battery, batteries, or a stand-alone power source like our PLB-40.

I got a question from a forum member and thought it would be helpful to share here as well.

The question was how long would the CFX3 75DZ run if using the Dometic PLB40 energy supply and the ambient temp was 75F?


Given that the PLB40 has 40Ah of capacity, ambient temperature is constant at 75F, and the 75DZ consumes .8-.9 Ah/h (rounding up to 1Ah/h just for simplicity) holding internal temp to 39F, you should get around 40 hours of use - little more/little less depending on how you have it packed, how many times you open it, etc.

If you were running the internal temp at 5F, the 75DZ would be consuming about 2.7Ah/h, so the run time with the PLB40 would be around 14-15hrs. Plenty for overnight, and you are on the move and charging the next day.

The best part of the PLB40 is that you can use it in-line (switched power from the vehicle to the PLB40 then to the cooler). As you drive, it charges the PLB40 and also powers the cooler. When you stop, it just pulls from the PLB40, so you aren't drawing down your main battery.

If you haven't seen this video it might be helpful...



And a good walkthrough by Main Line Overland...

One of the more complicated questions we get is relative to how our battery protection system works.


When does it know to shut off the cooler before you get to a no start situation (if you are using a single battery for your vehicle)? Even if you are using a secondary battery the same question applies except it removes the no start situation.


If you are using a single battery (starter battery) we recommend that you start out with our battery protection set to HIGH initially (and perhaps MEDIUM after you've done some testing to see how it works with your vehicle).

Here's why....

1. Voltage is sensed at the CFX DC socket and not at the terminals on the batteries. Many people don't realize just how much voltage loss occurs with thin gauge wire, poor electrical connectors, and old wiring. For example, a member of our team has a '87 FJ60. When trying to using the 12V socket in the dash, there is such a terrible loss that it won't power a CFX regardless of battery protection setting.
2. When current is pulled through a wire, the voltage drops by default, which causes more loss (Pukert's law).

Symptom

All the above can cause the battery protection to activate since the cooler isn't getting the power it needs - regardless of the reason. This also protects the cooler components.


Solution

If you have problems powering your cooler with your existing wiring pick up one of our DC Hardwire Kits. 10AWG direct from your battery to a socket for your cooler.



If you use a dual battery set up (in vehicle or one of our PLB40s) set battery protection to LOW.


Below is information showing at what points the battery protection for the CFX3 will kick in and shut the cooler down as well as in what range it will happily run.

We've started to see a couple of photos being posted up of new CFX3 models arriving at their new homes.

Anyone have a new CFX3 going into their Tundra? If so, would you post up a few photos?

Thanks!

In this new age of cleaning and sanitizing everything, we've seen a couple of questions come through from the forums that we thought would be helpful to share.

Question: Can I use Lysol or Clorox disinfecting wipes to clean inside/outside of the fridge?

Answer: Yes - this shouldn't present an issue at all. Just leave the top open after cleaning so everything can evaporate and you should be good.

You can also use a simple Dawn dishwashing detergent and water solution on a washcloth to wipe down everything. That should make it squeaky clean and pleasant smelling as well.

You might have seen on our site that we're experiencing shipping delays. I've got an email out to the team to get updates on CFX3 shipments along with availability/shipping updates on the CFX3 sliders and covers. I'll post here when I have updated information on these!

Hey @Dometic I need some help. What does “WARNING 09” on the display turned red mean? I’ve looked though my manual and can’t find an answer. The first time, it reset, but it’s happened again. Not paired with my phone and I don’t want it to be. Please tell me in plain language.

 

Ok. I’m hoping this thing is dependable. Getting support has been a very sloooow process, so far. Thanks for the update.
