Using the Bobrick B - 43699 is easy. First, open the dispenser using the flush tumbler lock. Load your 350 C - fold or 475 multifold towels into the dispenser part. For the waste receptacle, just open the removable front panel and put in a liner if you like. When it's time to empty the waste, open the front panel again and take out the trash. As for maintenance, regularly wipe down the satin - finish stainless steel surface with a soft cloth to keep it looking great. If you plan to retrofit an older TowelMate or LinerMate, refer to the accessories section. Always ensure the lock is working properly to keep your supplies secure.
