Place the Neff dishwasher on the ground in front of the space it will occupy. Have another person tilt the dishwasher backward so you have access to the front two feet of the device. Turn the screws on the bottom of each foot to adjust the height. Set the device back down and test with the level to ensure the device is level. If not, adjust the feet until it is.
Connect the drainage water line to the wastewater connection on the back of the dishwasher. Screw the connector of the hose to the connection on the back of the dishwasher. Use the wrench to tighten the connection securely. Do not overtighten or crimp the hose.
Connect the freshwater line to the inlet on the back of the dishwasher. This line should be a cold water line. Connect the line as you did the drainage line. Check the hose for any leaks or knots.
Connect the power cord of the device to the nearest grounded outlet. This outlet should be accessible once you put the dishwasher in place. Once the power supply is connected, you can push the dishwasher into the spot you want it.
