If you install the appliance on a slippery surface, it may move because of excessive vibration. Incorrect leveling may cause malfunction through noise and vibration. If this occurs, install the non-skid pads under the leveling feet and adjust the level.
Clean the floor to attach the non-skid pads.
Use a dry rag to remove and clean foreign objects or moisture. If moisture remains, the non-skid pads may slip.
Adjust the level after placing the appliance in the installation area.
Place the adhesive side c of the non-skid pad on the floor.
It is most effective to install the non-skid pads under the front leveling feet. If it is hard to place the pads under the front leveling feet, place them under the back leveling feet.
