A/C Condenser placement for an A1R

[IronhorseTX]

Hey folks, I’m starting to do the GEN two a/c install for my 2007 1085 A1R. Curious if there’s any documentation or if you guys can guide me on where the original placement is on the Reddot AC condenser on an A1R? Is it placed up front next to the radiator?

 

[Keith Knight]

Yes, mounted in front of the radiator and down low.

My thread on AC install on my A1R:

Gen 2 air conditioning install with C7 A1R - notes and pictures thus far.

I'm told by a MotorPool veteran of 20 years that "soft cab" trucks were basically never equipped with AC. He couldn't recall ever seeing one in fact. The A1P2 armored cab trucks all have it and in fact AC malfunction is a deadline. The AC only has to drop the ambient temp by 20 degrees F to be...

Curious if anybody knows where I can find the condenser mounting brackets for an A1R truck? Google searches aren’t helping.

 

[IronhorseTX]

Good news - no bracket needed. Found another way to mount it.





BUT the plugs don’t align to the trinary switch to the dryer I bought. Anyone know what plug is needed for this switch??

I am 1 ac Condenser fan unit away from having all the parts for my AO AC unit can you give a model number for that unit you have there

 

[Ronmar]

So replace the trinary switch with one compatible with your harness…

Condenser fit looks great…

@Ronmar Thanks - I got lucky on the fit. The harness came with the condenser and has the high and low connections. Curious if anyone knew which switch I could
swap out?



@FarmingSmallKubota - which model number do you need? Condenser? Or Gen 2 unit?

 

[Ronmar]

Ok, that looks like a config for separate hi and low pressure switches, and not a trinary switch(both hi and low combined)… you either need a new receiver/dryer with dual switches, a new harness to match your dryer with trinary switch, or to modify your existing harness and add a pigtail to connect to your existing dryers trinary switch… i think you will probably find that one pin in each of those connectors is either B+ or ground(common) connecting to the remaining 2 pins for high and low pressure indications respectively…

The outside condenser with fans that you have in the picture i have the GEN 2 inside unit

 

[IronhorseTX]

Am I better off swapping out the switch with this and then pigtailing?

Here it is, I bought it from Midwest Military. They don’t show that they sell it on their site because they keep them for their customer builds, but if you call they might sell you one.

That is probably the simplest option…
