Using this Elkay foot pedal accessory is easy. Simply step on the pedal to activate the bottle filler for a hands - free filling experience. Remember, it only activates the bottle filler and not the attached fountains. When installing, make sure to attach it to the lower access panel opening for a secure connection. In terms of maintenance, since it has a powder - coated exterior over Type 316 stainless steel, it can withstand the elements well. However, you should clean it regularly with a mild soap and water solution to keep it looking its best. Also, ensure it's compatible with your outdoor tubular bottle filling station before purchasing.
