vintage air genII magnum install

[peglegs]

i purchased a Vintage Air Gen II magnum air conditioning from a local that didnt want it he got it with a pkg deal and didnt care about a/c. it also came with a polished control panel and bulkhead connector bill of sale was for $1,000 + and i got for $500. has anyone installed this model or have anything negative about it? it will resell for what i paid for it to recoup my investment so keeping it is not my concern just that it will work for my 67. how is the heat output with these units? ty
