rupert - 10/19/2012 20:09 Had to install a 15 hp vfd for a fan to keep the power company happy. Local dealer comes and installs it and i get to checking it out and it says its a 30 hp drive. Call dealer and he claims thats what i need for a 15 hp fan??? Is he right or trying to hose me. Did some business with this guy this summer and dosent seem to be the most honest guy. He told me the price and i about died. Is he right or trying to oversell me? thanks
