ac unit

Thanks okan-star. I figured that adding up the amps like you did and came up with the same numbers.

The id motor is the fan motor that circulates the air inside the camper , it has low .7 amp and high .1.2 amp speeds .The od motor is only one speed all the time 1.6 amp , it blows on the compressor cooling fins
Added together on low- comp 8.9 , id.7 , od. 1.6 = 11.2 amps
on high -comp 8.9 , id 1.2, od 1.6 = 11.7 amps

I just ordered a Mach 8 Cub from Adventure RV. I am pretty excited about the 8.25" height. I will be taking on the task of installing it myself as my Bigfoot came pre-wired for the AC. It looks like the amp draw is 8.9 for the compressor and the ID motor is an additional .7 amp on low or an additional 1.2 amps on high. The OD motor has an additional 1.6 amp when high is selected. I am not sure what ID and OD motors are. Does anyone know?

Happy to see updated Technical information especially since it was mostly blank at the time I go my A/C installed and caused ALOT of confusion since I asked for a polar cub!

IT's A MACH 8 CUB! Just reminding myself......:S

Oh you should think of Airexcel as Coleman.......Do call or e-mail their customer service they don't mind being pestered with question, after question, after question! My frustration was relieved when I discovered an P/N miss written and I indeed had the MACH 8 Cub installed......Whew said it right!

:R

Sorry to leave y'all hanging after my last post! I did test my MACH 8 CUB with my Honda 2000 and everything worked great, even on the 20 am connection. Honda in eco mod rev'd up just fine and handles it no problem.

Mind you It was later Fall when I ran my test and so I had to shut the door and crank up the heat......Let things run this way for a while and am satisfied with my set-up but am looking for ward to more use/testing in various conditions this summer.

It is quieter on the low than the high setting, IMHO! I like lots of white noise having grown up in the tropics with fans running all the time!

Keep in mind the the MACH 8 cub is the lower profile unit from the MACH 8 group. Customer service at rvcomfort.com was awesome.

MACH 8 CUB News release

good thread, I was just looking at these units today.

no one mentioned the dometic unit, wonder why?

BTU`S dont equaly relate to amps and watts
There are higher BTU units with lower amps than the Mach 8 cub
9200 btu is just the compressers ability to cool
The mach 8 cub is probably quieter because it has lower cfm, 200, and it has two motors . One that cools the comp cooling fins that is not reduced in speed when you turn down the inside fan motor speed Most AC`S use the same motor, 2 fans on the same shaft , so reducing fan speed would reduce btus , not with 2 motors
BTU`S = A British Thermal Unit (BTU) is the amount of heat energy needed to raise the temperature of one pound of water by one degree F. This is the standard measurement used to state the amount of energy that a fuel has as well as the amount of output of any heat generating device.
You might be able to imagine it this way. Take one gallon (8 pounds) of water and put it on your stove. If the water it 60 degrees F. and you want to bring it to a boil (212 degrees F.) then you will need about 1,200 BTUs to do this.

The lower the btu rating the more readily a Honda 2000 will be able to start it up and keep it going. A lower btu rated AC will also be more efficient and more effective in removing moisture from the air. A higher rated AC will run for a shorter period of time and get the temp down but not remove nearly as much moisture from the air inside.

Having just purchased a camper and A/C I learned that the Polar Cub is no longer manufactured! Current production is the MACH 8 CUB 9200 BTU it is part of the new Mach 8 family but be careful with the name mach 8 as most of those units are the larger 13.5 BTU.

Here is the model number for the 9200 BTU MACH 8 CUB 47201A876

They still show alot of the Polar cub info in the technical section of www.rvcomfort.com and if you compare the old polar cub specs (49000 series) you will see that the Mach 8 cub is very similar.

Several e-mails with customer service at www.rvcomfort.com over a period of days finally got me straightened out....I was about to make my dealer change out my A/C unit until I learned they had installed the current production "CUB"! I'm going to be testing mine with a Honda 2000 soon.

Any update Exlporer? Is the Mach 8 cub quieter like they say on low speed?

Please report what you find,Exlporer
Thanks,Mike
