For the unit, you'd have to look at its manual. Some have oil-less compressors and made to recover several types of refrigerant, liquid/gas, etc. Mine is what they called a "station". It's older than dirt and I don't think it would like 134a because it has mineral oil.
I don't think one time would ruin it, but you might have mixed refrigerants...depending on what, if anything, was already in it.
