P/N 1010827 Rev. D 04/06

CAUTION

Ingesting the protective solution may cause irrita-

tion of the gastrointestinal tract, colic, diarrhea, or 

other similar symptoms

  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.

  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.

INSTALLATION (continued)

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.
