jeffw Posted May 24, 2016 Report Share Posted May 24, 2016 I'm trying to get mine working on shore power, since the truck came without the generator portion. If you have one and would be willing to answer a few questions, I'd really appreciate it. 2007 Volvo 780 Volvo D12D, 465hp, 1650 ft/lbs tq., ultrashift Link to comment Share on other sites More sharing options...
GeorgiaHybrid Posted May 24, 2016 Report Share Posted May 24, 2016 Jeff, I am having a shore power capable Carrier APU added to our new truck but it will be a couple of weeks before that is done. Can send you pics and info at that time. 2017 Kenworth T6802015 DRV 38RSSA Elite Suites2016 Smart Prime Link to comment Share on other sites More sharing options...

GeorgiaHybrid Posted May 24, 2016 Report Share Posted May 24, 2016 Jeff, you should have a distribution center under the bunk where the generator output ties in. I am ony phone right now but the ComfortPro manual can be downloaded and the install manual should have the points to connect shore power. 2017 Kenworth T6802015 DRV 38RSSA Elite Suites2016 Smart Prime Link to comment Share on other sites More sharing options...
jeffw Posted May 25, 2016 Author Report Share Posted May 25, 2016 I've got the 120V shore power cord connected where the generator would be. I connected the 12V (2 wire harness) to the batteries and ground, but the display won't come on. I talked to someone today who said I also need to put 12V/Ground on the 4 wire harness that would normally run to the engine control unit. He claims that without that the unit will stay dead. I'm going to try the 12v/ground on the other harness tomorrow and see what I get... 2007 Volvo 780 Volvo D12D, 465hp, 1650 ft/lbs tq., ultrashift Link to comment Share on other sites More sharing options...
jeffw Posted May 25, 2016 Author Report Share Posted May 25, 2016 Connecting the 12v/ground on the harness that would go to the engine control module did the trick. The schematic made it seem like it was an output from the main board to the engine control module, but apparently it's not. Now the display lights up the fan and condenser fan runs, but the compressor won't kick on. I suspect it's low on R22. Speaking of R22, can I still get it? 2007 Volvo 780 Volvo D12D, 465hp, 1650 ft/lbs tq., ultrashift Link to comment Share on other sites More sharing options...
GeorgiaHybrid Posted May 25, 2016 Report Share Posted May 25, 2016 Easy to convert it over to R-134. Almost any decent AC shop can do it for you. 2017 Kenworth T6802015 DRV 38RSSA Elite Suites2016 Smart Prime Link to comment Share on other sites More sharing options...
barlyn1 Posted May 25, 2016 Report Share Posted May 25, 2016 R12 is the one hard to get, r22 is an industry standard, later carrier apu used 134, mine is 2007 era and uses r22 and is serviced at any carrier dealer. 2001 ford f350, 2010 Jayco 351rlsa, 2002 Vw Beetle tdi toad, 2012 polaris rzr, 2004 yamaha zuma 2001 Freightliner c112 tandam axle, ism, 9sd manual, jackalope, mountain master air hitch, hayes 400b Link to comment Share on other sites More sharing options...
jeffw Posted May 25, 2016 Author Report Share Posted May 25, 2016 Ahh, I was confusing R12 and R22. That makes me feel much better. I think mine's from 2006. How's yours been? 2007 Volvo 780 Volvo D12D, 465hp, 1650 ft/lbs tq., ultrashift Link to comment Share on other sites More sharing options...
Imurphy907 Posted May 25, 2016 Report Share Posted May 25, 2016 R22 is still available, I buy it on a regular basis. R134a is a replacement. But there is no "drop in" replacement for R22. So some changes have to be made, those changes vary by the design of the system. I am a universally certified refrigeration tech. 2016 Road Warrior 420 2001 Volvo VNL 660 Alaska Based.
