UFC-420/440 water Filtration system

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.

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. Unscrew the cartridge end caps from the car-

tridge, being careful to retain the o-rings from

each cap. Set the o-rings aside.

9. Install a new cartridge to the system.

10. Connect the permeate port connection.

11. 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.

12. For each end cap, position the o-ring between the

end of the cartridge and cap and screw the cap

onto the cartridge. Tighten with strap wrench as

necessary.

13. 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.
