P/N 1010852 Rev. C 04/06
MAINTENANCE
The SE-4200/4400 Filtration system is designed to
require very little maintenance. To ensure that the
water is of the highest quality, occasionally some ser-
vice is required.
Checking the Controller Program
The program features and setting should be checked
occasionally to confirm that the system is operating
under the proper settings.
Follow the procedures outlined in the Operation section
of this manual to check and set the controller 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. Press the Stop button or close the Inlet Water
Valve and allow the system to depressurize.
3. Place a bucket under the filter cartridge to be
changed. Using a strap wrench, loosen, but DO
NOT remove the top and bottom End Caps.
4. Disconnect the Permeate Port connection.
5. Unscrew the cartridge End Caps from the car-
tridge, slide the caps past the cartridge ends, and
remove the old cartridge from the system.
6. Inset the new cartridge into the system
7. Attach the Permeate Port connection to the new
cartridge.
8. 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.
9. For each End Cap, position the cartridge and cap
and screw the cap to the cartridge. Tighten with
strap wrench, if necessary.
10. Repeat this procedure for the other cartridge.
11. Follow the Flushing and Starting up the System
and Sanitizing the System and Lines Procedures
in the Installation section of this manual to com-
plete the cartridge change.
SYSTEM SANITATION
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.
