Using this Bobrick B - 3094 dispenser is easy. First, make sure you've prepared the wall according to the specified rough wall opening dimensions. Then, mount the dispenser securely on the wall. For the toilet paper, simply place two rolls with a diameter up to 5 1/4' into the dispenser. When it comes to disposing of sanitary napkins, open the self - closing disposal door and put the napkin inside. Remember, the receptacle is locked with a tumbler lock, so keep the key handy. For maintenance, regularly clean the satin - finish stainless steel exterior with a mild cleaner to keep it looking shiny. Check the capacity frequently, and when it's almost full, empty the receptacle. That way, your dispenser will serve you well in your commercial space.
