Re: Converting factory AC to use R134a
Thank you!!
Here's what I drew up. This is my understanding of the wiring and the routing of hoses. Does this appear correct? AC COMPONENTS.pdf Last edited by ricachon7; 04-28-2022 at 04:23 PM. Reason: Remove attachment |

Re: Converting factory AC to use R134a
Looks pretty good to me. Here's the factory setup from the 1970 service manual.

Re: Converting factory AC to use R134a
For most later Generation AC system the hi low switch is a hi pressure cut out and low pressure cut out for the compressor..Hi pressure will/can blow up the system or burst a hose(no POV valve) and low if you loose the Freon so the compressor wont burn up..

Re: Converting factory AC to use R134a
Thank you, dmjlambert!!
I believe I understand now but I just want to make sure I do. Can I have the factory air set up just as shown on the diagram but instead of using the original type of compressor use a Sanden type and it works just the same? Do I not need to add a binary switch? Do I understand correctly that I do not need to be concerned about the compressor cycling if I keep the POA valve? |

Re: Converting factory AC to use R134a
That's my understanding but I don't have much experience. If you don't hear others chime in you may want to make a separate new thread.
