Using this soap dispenser is easy. First, install it on the countertop. If you're using the Multi - Feed system, make sure to buy the “6 - SOAP - MFT” Soap Multi - Feed Tank and connect it properly. For the power supply, you can either use a 4xAA alkaline battery pack or an A/C Adapter. When you place your hand under the spout, the touch - free dual sensors will detect it and dispense soap. The indicator light at the base of the spout will show you if it's powered on, when it activates, and when the soap is running low. As for maintenance, clean the exterior regularly with a soft cloth. Check the anti - rotational gasket/washer periodically to make sure it's in good condition. Also, follow the ADA guidelines when using it to ensure proper accessibility. Remember, this is a non - returnable item, so handle it with care.
