Using this toilet seat cover dispenser is easy. First, make sure there is at least 5 inches (125mm) of clearance from the bottom of the dispenser to the top of any horizontal projection. Then, fill the dispenser from the bottom through the concealed opening with single- or half-fold paper toilet seat covers. It can hold up to 500 seat covers. When installing, use two screws (not provided) to mount it on the wall or partition of the toilet compartment. For plaster or dry - wall, use concealed backing and #8 x 1 - 1/2 inches (4.2 x 38mm) sheet - metal screws. For other wall surfaces, you can use fiber plugs, expansion shields, 1/8 inches (3mm) toggle bolts or expansion bolts. To maintain it, simply wipe the satin - finish stainless steel surface regularly with a soft cloth to keep it clean and shiny. Avoid using abrasive cleaners that could scratch the surface.
