Place the pedestal washer in the final location and adjust the leveling legs on the pedestal washer to level it. Fully retract the legs of the front-loading washer.
Place the front-loading washer on top of the pedestal washer.
Place the leveling feet of the front-loading washer inside the bracket openings on the pedestal washer, and align the bracket screw holes.

Securely attach the two washers at the corners using screws.
First, insert screws on each side. Then insert screws on the front and back side.

For best results, level the pedestal washer before stacking the front-loading washer on top of it, and insert the screws in the recommended order.
Extend the feet of the front-loading washer slightly until the two washers are snug up against each other. To extend the adjustable feet, turn them clockwise for a half turn with a wrench. Then tighten the four lock nuts. All lock nuts must be tightened.

The pedestal washer will not work as a standalone unit.
