Pour approximately one cup of water into the drain assembly to form an air seal. This prevents gasses

Note for Single-Drain Units
Your unit might be equipped with just one drain and one drain plug. For these models, use the drain hose to
form a P-shape after connecting the hose to the drain plug (the arc of the P should be wide enough so as not to
cause a kink in the drain hose). Fix the P-shape with one of the (two) plastic cable-ties provided, taking care not
to pinch the hose when tightening the cable-tie.
