SE-4200/4400 WATER FILTRATION SYSTEM

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.
