Using your Bradley Metro Series soap dispenser is easy. First, make sure you've got the right power supply, either the battery pack or the A/C adapter. If you're using the multi - feed system, install the “6 - SOAP - MFT” Soap Multi - Feed Tank. Just wave your hand in front of the dispenser, and the touch - free dual sensors will activate to dispense the foam soap. The indicator light at the base of the spout will let you know if there's power, when it's activated, and when the soap is running low. Remember, this item is non - returnable. For maintenance, keep the dispenser clean with a soft, damp cloth. Avoid using abrasive cleaners as they might damage the polished chrome finish. Also, check the anti - rotational gasket/washer regularly to ensure the dispenser stays secure. And always use non - proprietary bulk foam soap to keep it working well.
