Many times these blowers will simply be labeled to connect for "low voltage" or "high voltage". This allows for use of the same label in different countries. Assuming yours is tagged for 120/240 then that is the low and high being referred to. Three phase units require extra care to get not only the voltage but rotation correct. Chances are yours is single phase so you need only get the voltage and it's capacitor hooked up right. It may take me a day or so as we are moving but I will be happy to help you if there is still an issue, you may email me at neonarchaeology@gmail.com
