SECTION 4 INSTALLATION
4-1. Specifications
If the unit is operated from a 30* ampere, 115 volt circuit or a 15** ampere, 230 volt
circuit, a different input power plug must be installed on the power cord. See
Section 4-9 for instructions.
NOTE
*A 30 ampere branch circuit is recommended for maximum performance. Performance on a 20 ampere branch service may be limited due to the circuit
breaker or line fuse. Reducing unit output amperage will minimize circuit breaker tripping or blowing a line fuse.
**A 15 ampere branch circuit is recommended for maximum performance. Performance on a 10 ampere branch service may be limited due to the circuit
breaker or line fuse. Reducing unit output amperage will minimize circuit breaker tripping or blowing a line fuse.
