There are 2 channels in the bottom of the dishwasher for routing the water and electrical connections.
As shown in the bottom view below, channel a is for the water supply line, and channel b is for the electrical cable.

Turn off the house water supply and the circuit breaker or dedicated power before connecting the dishwasher.
Run the water supply line along the floor 6 1/2" – 7 3/4" (165 mm – 197 mm) from the left side of the opening and tape it in place in front of the opening.
Run the electrical cable c along the floor 14" – 16" (356 mm – 406 mm) from the water supply line d and tape it in place.
The electrical outlet must be within 4 ft. (1.22 m) of either side of the dishwasher.
The best location for the electrical conduit is on the right side of the back wall. Re-route the electrical cable before installation if the electrical conduit pipe is longer than 3" (76 mm) and is centered on the back wall.
