Using this dispenser is easy. First, load up to two rolls of up to 5 - 1/4 - inch core toilet tissue and 1000 single - fold or half - fold toilet seat covers. When you need to access the supplies, use the hinged access door on one side. For the waste receptacle, it has a 1.0 - gallon capacity, so empty it regularly to avoid overflow. When installing, make sure to verify all the rough - in dimensions first. Use the included mounting screws at the provided holes. If you want to use a grab bar, the recessed unit is a great choice as it allows clearance for it (grab bar not included). For maintenance, wipe the stainless steel parts with a mild cleaner to keep the architectural satin finish looking good. Check the tumbler locks and hinges periodically to ensure they work smoothly. If you need napkin disposal liners, order the box of 500 with part number P11 - 022.
