230/single phase? If so, you need a two pole breaker (20 or 30 amp) with 12-2 wire. Then, WHT/WHT, BLK/BLK, GRN/ground. Label the the line white with red tape or heat shrink to indicate it is hot, not neutral. Consult your owners manual for exact power requirements. If you don’t have it, I bet you can download it or at least contact the manufacturer.
