This varies based on model. With some models you simply screw the hose onto the outlet on the back of the unit. With other models you have to remove the bucket, feed the hose through the back of the unit and connect to the adaptor above the bucket area, then replace the bucket. It is important to look at your control panel. Some units have a “continuous drain” button on the control panel. If that is the case for your unit, you must press this button after the hose is in place or the function will not work. Please refer to your owner’s manual.
