UF SERIES WATER FILTRATION SYSTEM

INSTALLATION (continued)

1.Plug the power cord into the appropriate electrical outlet. The unit will power up and the LED display will display the following for about two seconds each:

•8.8

•F8 followed by its time settings in seconds

•Fi and its time setting in minutes or hours.

The F8 and Fi sequence repeats for 30 seconds after which the unit automatically returns to the Flush Interval Mode (Fi). The time setting for Fi will be displayed and the decimal point will flash in one second intervals.

CAUTION

Ingesting the protective solution may cause irrita- tion of the gastrointestinal tract, colic, diarrhea, or other similar symptoms

2.Open the tap or faucet closest downstream to the filter system.

3.Slowly open the inlet water valve and allow water to enter the system.

4.Press and hold the Start button. After 6-7 sec- onds, the drain valve will open and FL will appear on the display.

5.Continue holding the Start button down for at least 30 seconds to keep the drain open. This flushes air out of the center of the hollow fibers of the car- tridge filter. The drain will remain open as long as the Start button is pressed. Check to make sure that the drain water is directed into the drain with- out splashing.

6.Release the Start button. This closes the drain valve. Water should continue to flow through the system and out of the open tap. Allow water to flow out of the tap for at least 15 minutes at maxi- mum flow rate.

7.Close the tap and let the system stand without water flow for 15 minutes to allow any trapped air to come out of the hollow fibers. Check for leaks at all fittings.

8.After 15 minutes without water flow, open the tap for 5 minutes to allow any trapped air to be flushed out.

9.Close the tap. Flushing is complete.

SANITIZING THE SYSTEM AND LINES

The plumbing must be sanitized to eliminate possible contamination that may have occurred during the instal- lation process. Chlorine bleach can be used to sanitize the plumbing. The amount of bleach used depends on the size of the system installed and the amount of plumbing downstream of the filter system. Generally, one ounce (30 ml) of bleach will be sufficient to sanitize the system.

1.Make sure that the system has been flushed of air and debris as described in the Flushing and Starting up the System section of this manual.

2.Open the tap closest downstream to the filtration system and close the inlet water valve and allow the system to depressurize.

3.Place a bucket under the strainer at the inlet connection to the system. Open the strainer by unscrewing the cap. Water will flow out of the strainer as the system drains.

4.When the water flow from the strainer stops, pour the liquid bleach into the strainer. Be careful not to spill bleach onto clothing or skin. Re-attach the cap on the strainer.

5.Slowly open the inlet water valve and allow water to flow out of the tap until the smell of bleach is present.

6.Close the tap and let the system stand without water flow for at least 15 minutes to allow the bleach to sanitize the pipes.

7.After 15 minutes without water flow, open the tap and flush until the presence of bleach is gone. All other taps should be opened to flush any bleach from the plumbing.

8.Close the tap. The sanitization is complete.

Program the timer following the procedure outlined in the Operation section of this manual.
