1.0 Preparing Bleach Solution
Prepare a disinfecting solution by adding one tablespoon (15ml) household bleach per gallong (4.5L) of water solution. Label the Bleach Solution container with your name, the contents, and the date. Bleach Solution must be used within 30 days.
2.0 Cleaning of Water Dispenser
Note: This procedure is most easily performed before changing out an empty bottle.
2.1 Unplug the cord from electrical outlet of water dispenser.
2.2 Remove empty bottle.
2.3 Use disposable gloves and safety glasses when working with bleach.
2.4 Using the sponge, scrub interior surface of the water cooler reservoir thoroughly with the Bleach Solution and let stand for not less than two minutes (to be effective) but not more than five minutes (to prevent corrosion).
2.5 Drain the Bleach Solution from reservoir through faucet(s) into a bucket.
2.6 Dispose of the Bleach Solution into the sanitary system.
2.7 Rinse the reservoir thoroughly by filling the reservoir with clean tap water or bottled water four (4) times. Drain the rinse water through cooler faucets into a bucket. This will remove traces of the Bleach Solution.
2.8 Dispose of rinse water into the sanitary system.
Note: Do NOT use Fantastic cleaner or similar products on plastic parts. These products contain chemicals that can cause the plastics to beome brittle or discolored.
