HOW TO CLEAN A WATER DISPENSER

1.Unplug the water cooler from the wall ,and remove the bottle .

Make sure there's no other electronics plugged into the same outlet,or near the area where you've chose to clean your water cooler .This avoids any possibility,however small ,of water meeting live electricity.

2.Wet a sponge to clean the inner surface of the water with the cleaning solution. 

Let it stand for 2-5 minutes (but no more to avoid wear and tear),then drain solution through the tap(the cool temperature one if there are two )and into a separate container.Drain this container down a sink or toilet.

3.Rinse out the remaining cleaning solution.

Fill the inner reservoir with water four times and pour it our through the (cooler temperature) tap and into a bucket .Be thorough in this to make sure no bleach or vinegar taste is left behind.

4.Lift off the drip tray and scrub well.

Wash both the tray and the screen (if present )and rinse both in clean tap water before returning them to the dispenser .Be sure to dry thoroughly so as not to leave moisture in any tight spaces.

5.Wash your hands well,and dry the new bottle with a towel.

Be sure to wash your hands before manipulating the bottle again.

6.Remove the cap and place the new bottle.

Ensure a snug fit,and watch for air bubbles rising to the top of the bottle ,indicating the bottle has made a seal with the dispenser.

7.Check that it works.

Fill a glass of water ,try both faucets if your dispenser has them .Taste the water to make sure no unpleasant has been left behind.
