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, fill the soap tank through the top fill port. Choose your power supply, either the battery pack or the A/C adapter, and install it according to the instructions. When you place your hands under the spout, the touch - free dual sensors will detect your hands and dispense soap. The indicator light at the base of the spout will let you know if there's power, if the dispenser is activated, and when the soap is running low. Remember, this is a non - returnable item. For maintenance, keep the dispenser clean by wiping it regularly with a soft cloth. Check the anti - rotational gasket/washer periodically to ensure it's in good condition. This dispenser complies with ADA guidelines, so it's suitable for various settings.
