Using this soap dispenser is easy. First, make sure you've purchased the “6 - SOAP - MFT” Soap Multi - Feed Tank if you're using the Multi - Feed system. Then, choose your power supply, either the battery pack or the A/C adapter. Once it's powered on, the indicator light at the base of the spout will show you the power status. Wave your hand in front of the dispenser, and the touch - free dual sensors will activate to dispense soap. When the soap is running low, the indicator light will let you know. Remember, this is a non - returnable item. For maintenance, regularly check the anti - rotational gasket/washer to ensure it's in good condition. Clean the dispenser with a mild cleaner to keep its polished chrome finish looking great. Keep it away from harsh chemicals and excessive force to maintain its vandal - resistant construction.
