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 4-9for instructions.

*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.

Duty Cycle is percentage of 10 min- utes that unit can cut at rated load without overheating.

If unit overheats, thermostat(s) opens, output stops, Temperature trouble light goes On, and cooling fan runs. Wait fifteen minutes for unit to cool or temperature light to go off. Reduce amperage or duty cycle before cutting or gouging.

! Exceeding duty cycle can damage unit and void warranty.
