Have HVAC Questions? Ask an HVAC Expert for Answers
I can try to help you out here. Please tell me the manufacture and brand name. I am assuming this is an older unit so please look to see the brand and on the data tag(s) who manufactured it. many times these units are manufactured by one and other.
Here is a link to the installation manual and wiring for the models you requested. Let me know if the link does not work. I have it on a PDF. but I cant seem to attach it here.
If I can be of further assistance please let me know.
