Operation and Cycle Information
This section of the guide provides details on segments of cycles, timing of cycles, temperature expectations
and cycling of the heater during the dry portion of a cycle.
Auto Hot Start
If incoming water temperature is below 80°F, Auto Hot Start is initiated at the beginning of the cycle in an
attempt to purge the home water lines of cooler water. Auto Hot Start can add up to 10 minutes to overall

segment of the cycle.
Cycle Times
Times will vary depending on options selected, incoming water temperature, and soil level (some models).
Incoming water temperature of 120°F - 140°F is recommended. The 4 pass heating element quickly heats
the water for optimum performance.
