manual flushing
nOte: manual flushing only works when unit is in
flush Interval mode (fi).
While the unit is in Flush Interval Mode (decimal point
flashing), hold the start button down for 6-7 seconds
until the LED displays FL (Figure 13). Continue hold-
ing the button down to keep the drain open. Drain will
remain open for as long as start button is depressed.
(FL will flash on LED.) Releasing the button closes the
drain and puts the unit back into startup mode. After ten
seconds, if the start button is not pressed the unit auto-
matically returns to the Flush Interval Mode (Fi).
The filtration system is designed to require very little
maintenance. To ensure that the water is of the highest
quality, occasionally some service is required.
checking the timer program
During normal operation, the system displays the time
setting for the Flush Interval Mode (FI) and the deci-
mal will flash in one second intervals. This is the time
between flushing, not a time of day setting.
Over time, it is possible that the time that the system
flushes occurs at a time of high water use. If that cre-
ates a problem, the timer can be reset by unplugging
the power cord, waiting for 5 seconds, and plugging the
power cord in again. The timer then begins timing from
the point power is restored to the system. Follow the
procedures within the Operation section of this manual
to check and set the timer settings.
changing the cartridges
While the filtration system is designed for long life,
eventually the cartridges will need to be replaced.
1. Open the faucet or tap closest downstream to the
filtration system.
2. 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. Press and hold the start button to help drain
the system.
maIntenance
5. Reattach the cap on the strainer when the water
flow stops. Unplug the power cord.
6. Using a strap wrench (up to 6" capacity), loosen
the top and bottom end caps. Do NOT remove the
top and bottom End Caps yet.
7. Disconnect the permeate port connection.
8. Using a screwdriver, remove the screws from the
cartridge bracket and set the bracket and screws
aside.
9. Unscrew the cartridge end caps from the cartridge.
10. Install a new cartridge to the system using the
cartridge bracket and screws saved from Step 8.
11. Connect the permeate port connection.
12. Inspect the O-rings to make sure they are clean
and are not splitting or cut. For all O-rings, make
sure they are lubricated with an approved food
grade lubricant acceptable for drinking water use.
13. For each end cap, screw the cap onto the car-
tridge. Tighten with strap wrench as necessary.
14. Follow the Flushing and Starting the System and
Sanitizing the System and Lines procedures in the
Installation section of this manual to complete the
cartridge change.
sYstem sanItIZatIOn
Over time and use, the plumbing downstream from the
system may require sanitization. It is recommended
that the system and downstream plumbing be sani-
tized at least once a year. When necessary, follow
the Sanitizing the System and Lines procedure in the
Installation section of this manual.
