Retooling '91 tub. Replacing pump and topside control & the spa pack: Balboa VS510SZ PN 54371HC3 . Would like to re-use older (2003), occasionally used, 110v air blower. Looks like electrical diagram shows only one blower plug and its rated 240v. Is it possible to use 3 and if so which 3 of the 4 (AMP-4?) plug in holes on the board or do I need to buy new blower? Thanks
