4-3. Duty Cycle And Overheating

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

If unit overheats, 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 duty cycle before cutting.

Y Exceeding duty cycle can damage unit and void warranty.
