How do I select the correct electrical input for the Spectrum 625?

The Spectrum 625 has Auto-Line circuitry that automatically adapts to either 120V or 240V AC input. For 120V, a 15 or 20 ampere individual branch circuit protected by time-delay fuses or circuit breaker is required. For 240V, follow the electrical service guide in Section 5-6. Check the rating label on the unit and verify the input voltage available at your site before installation.
