DI CARTRIDGE REPLACEMENT:
1. Without a TDS meter, you will have to determine when to replace the DI cartridge.
Monitor the color-changing DI resin for exhaustion. The resin will start to change
color at the indicator label on the cartridge. The color change will grow upward and
should indicate exhaustion when the color change gets to the top of the cartridge.
2. A better and more accurate method would be to use a hand-held TDS Meter.
Measure a sample of product water in a CLEAN cup. If it displays “001 ppm” or
higher, it is time to replace the SilicaBuster™ DI cartridge. (Part # DI-SB-CI-10) You
may also replace it with our new SilcaBuster™ Extended Life Super DI cartridge
(DI-SB-CI-10HC). It has greater capacity, yet still fits in your housing.
3. Turn the system off and remove the cartridge housing by rotating it counterclock-
wise until it is free of the threaded head on the bracket.
4. Make sure the new DI cartridge is installed in the correct direction as marked on the
cartridge shell and be sure that the top seal is securely attached to the top of the cartridge.
5. Tighten the cartridge housing by rotating it clockwise and hand tighten.
6. Turn on system and check for leaks.
RO MEMBRANE REPLACEMENT:
1. Turn off the water supply to the RO system. Place the system where the
membrane housing(s) can be easily accessed.
2. Remove the black tubing from the membrane feed push fitting by depressing
the collar on the fitting with your thumb and pulling the tubing from the push
fitting. You should not have to remove the blue and yellow tubes.
3. Lift the membrane housing from the retention clips and unscrew the
membrane housing cap. This may require two people.
4. Use a pair of pliers to grasp the membrane stem and pull the membrane from
the housing.
5. Remove the black housing O-ring. Wash the empty housing with soapy
water. Rinse thoroughly with hot, clean water.
6. Insert the new membrane into the housing, with the double o-ring end first.
The o-rings and tube must fit into the recess at the bottom of the membrane
housing. When the membrane is aligned with the recess, firmly push the
membrane into the recess until it bottoms out.
7. Place the black housing O -ring on the housing rim and carefully screw the lid
back on to the base. Hand-tighten.
8. Reconnect the black tubing to the membrane feed push fitting.
9. If you have a dual-membrane system (-180), perform steps 2 thru 8 on the
second membrane.
10. Open the Flush Valve and allow the system to flush for several minutes to
remove any loose particles.
11. Close the Flush Valve and turn on the water supply to the system.
12. Check for leaks.
