PREFILTER/POSTFILTER MAINTENANCE

NOTE: It is recommended to replace the battery, prefilter and postfilter cartridges at least every 6 months of prod-

uct water use. Replace more often if they begin to plug with sediments.

The prefilter and postfilter are replaceable sediment car- tridges with activated carbon in its composition. See Figure 25. You must periodically replace the prefilter and postfilter cartridge. This will protect the RO membrane from being destroyed by chlorine. It will also prevent the filters from plugging with sediments.

You may notice a slower output of product water as the prefilter and postfilter build up with sediments. Replace the prefilter and postfilter cartridges when this occurs.

You should replace the battery whenever you replace the cartridges.

RO MEMBRANE CARTRIDGE MAINTENANCE

The Reverse Osmosis cartridge is a tightly wound special membrane. See Figure 25. The membrane reduces the dissolved solids and organic matter. The life of the Reverse Osmosis membrane cartridge depends mostly on the pH and hardness of the supply water. (see specifi- cations). Cartridge life is shorter with higher pH. For example, if supply water pH is from 6.8 to 7.7, the car- tridge may last for well over one year. However, car- tridge life may be as short as 6 months if the pH is as high as 8.5 to 10. Higher pH weakens the cartridge mem- brane and causes pin-hole leaks, it's time to replace the Reverse Osmosis cartridge when the production rate and/or quality of product water drops. Product water may begin to taste different or bad, indicating solids and organics are passing through the Reverse Osmosis mem- brane. See Reverse Osmosis cartridge replacement.

REVERSE OSMOSIS CARTRIDGE REPLACEMENT Complete the following steps to replace the cartridges.

1.If possible, turn off the water supply to the RO system.

2.Remove (turn to the left) the pre filter cartridge from the filter head to relieve pressure on the Reverse Osmosis cartridge.

3.Remove the Reverse Osmosis cartridge.

4.Remove the postfilter cartridge.

5.Discard the cartridges in a proper manner.

6.install new cartridges in reverse order (postfilter, Reverse Osmosis and then prefilter). Turn cartridges to the right to re-attach to the filter heads.

7.Remove and replace the timer battery. See Figure 14.

8.Turn on the water supply to the RO system.

9.Purge the Reverse Osmosis membrane cartridge. See page 17 for instructions.
