Using the Elkay ezH2O floor - standing bottle filling station is a breeze. Just place your bottle under the spout, and the no - touch sensor will activate the water flow. The filling will automatically stop after 20 seconds. You can install it anywhere indoors where there's a water supply and drain. For floor - standing installation, ensure the base is stable. If you choose a wall - backed setup, make sure the wall can support it. When it comes to maintenance, keep an eye on the LED filter status indicator. When it shows that a filter change is needed, replace the 3,000 - gallon filter. This filter is certified to keep your water clean. Also, make sure the refrigeration system is working properly to get chilled water. And don't forget, by using this filling station, you're helping to reduce the use of disposable plastic bottles.
