4. The hot water supply must provide a minimum of 140°F/60°C, measured at the dishwasher for the 40°F/ 22°C rise booster.

5. For the 70°F/39°C rise booster the hot water supply must provide a minimum of 110°F/43°C measured at the dishwasher.

Drain Connections

ATTENTION

Do not connect the drain hose to a disposer. The dishwasher will not drain correctly.

1. The dishwasher has a 6ft. 3/4" I.D. drain hose. The maximum drain height

connection must not exceed 3 ft.[9 m].

The recommended drain height is 17" [.4 m] or less above the oor.
