Using this Bobrick combination unit is easy. First, install it following the rough wall opening dimensions provided. Load the dispenser with either 600 C - fold or 800 multi - fold towels. When someone needs a towel, they can simply pull one out. The waste receptacle is there to collect trash. Empty it regularly when it gets full, as it has a 15 - gal capacity. For cleaning, just remove the front panel. Keep the unit looking good by wiping it down with a mild cleaner from time to time. If you want to retrofit TowelMate or LinerMate, make sure to check the accessories section for the units installed before the specified dates.
