SELF-CLEANING FUNCTION This bottom loading water dispenser has a built-in UV light that turns on automatically when the pump is working. The UV lamps purify the water and prevent harmful substances from building up in the water, tank and plumbing, ensuring that every sip of water you drink is healthy and clean. And, the UV lamp automatically cleans and operates for 20 minutes every hour, so you'll always have clean, great-tasting water.

Three temperature choices you can independently choose your desired temperature between cold water (46.5-51°F), room temperature water, and hot water (185-194°F). Heating capacity 5L/H, Cooling capacity 3L/H, you can determine the cooling or heating situation according to the prompts of the indicator light. When the water bottle runs out of water, the heating light and cooling light flash at the same time to remind you to replace the water bottle.

BOTTOM LOADING Using standard 3 or 5 gallon bottles (bottles not included), the bottom loading design makes changing bottles safer and easier.

The bottles are hidden behind a stainless steel door, so your bottom loading cooler always retains its sleek, elegant look.
