Help needed. Installing Carrier Comfort Pro APU

I would check out YouTube for videos on APU installation and servicing to get some ideas on what you will need to do.

I would also go down to a Carrier Stealership and ask one of the Techs there if they could answer a few installation questions.

 

I can't help with your install, but get an extra fuel pump for that thing to have on hand when the one in it craps out. I fought with that same type and vintage unit for years on my old truck. The fuel pump is easy to swap out, but not always easy to find when you need it.

 

I know I'm late with this post, I have experience installing these if you still have questions but I assume you have it running by now.

 

Tripac is more quiet and reliable. The engine is 2cyl Yanmar Made in Japan. Life of the engine is about 50 000 hours. Many people said it even runs up to 70-80 000 hours with good maintenance. I purchased a truck with this APU on 5000 hours - practically new. I am changing 2 fuel filters, 1 air filter - once a year, but the oil filter and oil as soon as the oil gets black and only use 5W40 - 100% synthetic. Dello 5W40 is $20 at Walmart. It takes 1 gallon of oil. Manual says - do the service once a year or every 1000 hours, but I prefer to play safe and keep the engine run clean....

 

Can you assist me. I had a used one installed
Carrier apu. The problem I face is I have apu running and forget to turn off when I hit the road. A couple of times it’s runnjng w truck engine for hours. I just replace. A battery that got ruined cause of it.
Still I forget to turn off. It should have a way that once power is turned in it kills the system so you don’t overcharge batteries

 

Bedtime, you need to take a look at the schematics which can be downloaded online. All you need to do is run a wire that will output 12 volts from the alternator after the engine is started to the relay mounted in the upper part of the engine compartment on the frame. The system will cut the engine off when voltage is present at that relay. Any Carrier tech can do that for you after hours in a parking lot for you and charge a lot less than his shop would.
