 The sanitization procedure is performed to reduce/eliminate any bacteriological 
 growth in the cooler tanks and dispensing plumbing. Bacteriological growth
 can be the cause of some taste and odor in the water.
The procedure is as follows:
• Mix 1 teaspoon of common household bleach (5.25%) in 2 gallons of
 clean water.
• Unplug the cooler from the power source.
• Drain all water from the cooler tanks.
• Pour the sanitizing solution into the main (cold temperature) tank until full.
• Open all spigots to allow sanitizing solution to fill the dispensing faucets.
 Close the spigots.
• Let the sanitizing solution stand in the cooler for 10 minutes. 
CAUTION: Leaving the sanitizing solution in the cooler for more 
than 10 minutes can cause taste problems in the water.
• Completely drain the sanitizing solution from all the tanks per section 10
• Fill the main (cold temp.) tank with clear tap water to rinse out the 
 sanitizing solution.
• Completely empty the rinse water from the tanks.
• The cooler is now sanitized and ready for filling with filtered water.
