SANITIZING THE WATER STORAGE TANK

You should sanitize your water storage tank before installation and once a year after that. This will remove any bacteria that may have invaded the tank. For sanitizing it during the initial installation, please see the Installation Instructions. For subsequent sanitizing, here is the procedure:

a. Turn off the water going to your R.O. system and open the faucet to drain the system completely.

b. Disconnect the tube at the tank by unscrewing the nut.

c. Go to the tube going from the right vertical housing to the small white automatic shutoff switch and unscrew the nut which connects the tube to the automatic shutoff switch. Then reconnect that end directly to the tank.

d. Remove the sediment pre-filter from the left vertical housing and screw the housing back onto its cap.

e. Remove the carbon pre-filter from the right vertical housings and pour in 1/4 cup of liquid household bleach. Make certain the "O" ring is in its groove and screw the housing back onto its cap.

f. Turn the water back on and check for leaks. The water will flow into the vertical housings and then carry the bleach into the tank.

h. Once the tank is full (approx. 5 minutes), turn off the water and shut off the tank valve. Wait 20 more minutes so the bleach has time to kill any bacteria in the tank.

i. After the 20 minutes, move the tank to a place where you can drain it (such as outside, the shower, or the sink). Open the tank valve just a little at first because the water will shoot out with great force. Wait until the tank is completely drained. (Most tanks hold 2 - 3 gallons of water. If you don't notice that much water coming out of the tank, you may need a new tank.)

j. Refill the tank with regular tap water and then drain it. (The purpose of this is to rinse out the bleach solution from the tank.)

k. Put the tank back in place and reconnect the tubes in their original configuration.
