Installation
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 floor.
2.The drain hose is secured to the rear of the machine by a clamp to maintain a goose-neck bend in the drain hose.
DO NOT REMOVE THE DRAIN HOSE RETAINING CLAMP. DO NOT STRETCH THE DRAIN HOSE.
3.A 3/4" hose barb fitting is strapped to the drain hose to use in connecting the drain hose to building drain line.
The service part number for the hose barb is P/N 0512321.
4.Install the drain hose to a "WYE" drain fitting. Connection to a "TEE" fitting will prevent the dishwasher from draining completely.
5.The maximum drain flow is 8 U.S. gpm/7 Imp. gpm/30 L.P.M.
6.Make sure the drain hose does not kink. Kinks will prevent the dishwasher from draining completely, and the dishwasher will overflow out the front door.
NOTE: DO NOT CONNECT THE DRAIN HOSE TO A DISPOSER. THE DISHWASHER WILL NOT DRAIN CORRECTLY.
The dishwasher flexible drain hose must be connected to a WYE fitting.
Do not connect the dishwasher flexible drain hose to a TEE fitting.
