The most convenient time to clean your cooler is when the bottle is empty.
Before you begin cleaning the reservoir of your water dispensing equipment, have the following suggested items handy.

•  Clean rubber gloves.
•  Lint free paper towels or other clean, dry lint free cloths or towels.
•  Clean dish type scrub brush, with a long handle to help you reach the bottom of the reservoir.
•  Plastic scrubbing pad. Never use soaps or detergents, steel wool, or other abrasives on your reservoir!
•  Measuring spoon, one teaspoon volume.
•  Calibrated container. e.g.2 gallon pail.
•  Unscented household laundry bleach.
•  Clean 1 gallon container filled with bottled water.

How to Maintain Your Bottled Water Cooler

Steps to clean a cooler

•  Unplug the Power Cord.
•  Remove the bottle. If there is any water in the bottle, make sure that you cap or cover the bottle for re-use.
• From the COLD FAUCET drain all water from the cooler into a bucket. Discard this water.
•  Remove the cooler top. If the cooler is equipped with a no-spill device it may need to be removed first.
• Look in the reservoir to see if there is a removable baffle. If there is any, remove the baffle.
•  If there is water remaining in the cooler, drain it out. If the reservoir has an ice ring in it, add hot water to melt the ring and completely drain the reservoir. Do not spill water outside of the reservoir into the interior of the cooler.
•  Prepare a cleaning solution in the calibrated container by adding one teaspoon of unscented household liquid bleach to each gallon of water.
•  Wear clean rubber gloves: Immerse the lint free towel and/or scrub brush into the cleaning solution. Squeeze all excess cleaning solution from the towel and aggressively clean all surfaces of the reservoir interior. Do not pour the cleaning solution directly into the reservoir.
•  Rinse the reservoir. Carefully fill the reservoir with bottled water from the 1 gallon container to 1/2 inch from the top of the reservoir. Completely drain the rinse water from the reservoir through the cold faucet.
•  Use the same cleaning solution brush and/or cloth, to clean the baffle, the cooler too, drip receptor and faucets. If your cooler is equipped with a no-spill device, it should be cleaned with this same cleaning solution. Take care not to get the air filter wet. Use the clean 1 gallon container filled with bottled water to thoroughly rinse these parts.
•  Wearing the rubber gloves re-install all parts: baffle, cooler top, faucets if removed and no-spill device (if equipped).
•  Place a bottle back on the cooler and drain two cups of water from each faucet, or until there is no evidence of a chlorine taste and/or odor. Dry all spilled water on the cooler and the floor.
•  Plug the cooler back into the electrical outlet. Allow forty five (45) minutes for the water to reach the appropriate temperature.
