If you have a Crystal Mountain water cooler in your home or office, it's very important that you clean it regularly. Your water won't stay clean if the base and dispenser are soiled. Cleaning is fairly simple and only takes a few minutes. Take the time to clean the cooler at least on a weekly basis.
Unplug the base and pull off the water bottle. Set the bottle upright on the floor. Place a cup underneath each faucet and turn them on to drain out any remaining water. If your cooler has a hot water feature, flip the switch on the side of the heating tank to turn it off. Wait for the water to cool off before proceeding to Step 2.
Place the plastic tub behind the cooler and pull out the white plug on the back of the base. It will be on the left side near the bottom. Let the water drain into the tub.
Stand in front of the cooler and look at the top of the base. You'll see a white plastic pin near the back. Pull out the pin and put it in a safe place. Turn the ring on top of the base counterclockwise to remove it. Pull out the baffle cup, which is a white plastic bowl about six inches in diameter. Put the drain plug back in the base.
Mix 1 gallon of lukewarm water and 1 ½ tablespoons white vinegar together in your bucket. Pour the contents into the reservoir. Let set for five minutes. Dip a cotton cloth into the reservoir until it is saturated with solution.
Use the cloth to wipe the sides of the reservoir, the faucets and the baffle cup. Drain the reservoir by pulling out the plug, as in Step 2. Flush it with water three times by filling it and draining it out.
Put the cooler back together and run each faucet for 10 seconds.
