It is important for the service person to have clean hands while handling inner parts of the system. CAUTION: Be sure to remove the RO membrane and both filter cartridges as follows, before sanitizing. Be sure the water supply to the RO is turned off, and the RO faucet is open to relieve pressure. 9, page 11, press inward while turning the RO cap to the left (?) to remove from the bracket/membrane housing. Replace the RO cap and push inward while turning to the right (?) to lock. Add 1. 0 ounce of chlorine (ordinary 5. 25% household bleach . . . Hilex, Clorox, etc. ) and mix in the water. Carefully replace the sump on the prefilter head and tighten securely. Allow water to circulate through the RO system until you smell the bleach odor. After the 20 minutes, open the RO faucet and run water until the bleach odor is gone. The prefilter (left side) cartridge has light gray coloring, and the postfilter (right side) has blue coloring. PRESSURE TESTING 1. Open the main water supply valve and several house faucets to purge air from the system. Note: When the system is first pressurized, water may `spurt' ` 'from the faucet airgap hole until air is expelled from the RO system. PURGING RO MEMBRANE Important purging instructions: The RO cartridge contains a food grade preservative that you should clean from it before using water from the system. The preservative will give product water an unpleasant taste and odor. 1. Then, open the RO faucet and empty again. Repeat steps 1 and 2 to purge the storage tank 4 times.

The prefilter has a replaceable sediment cartridge with activated carbon in its composition. The cartridge (10 micron) removes sand, silt, dirt, other sediments, and up to the ppm of chlorine shown in the specifications from the feed water. Filtered, clean, chlorinefree water flows from the prefilter, to the RO membrane cartridge. REVERSE OSMOSIS (RO) CARTRIDGE The cartridge inside of the RO housing, is a tightly wound, special membrane. Water is forced through the cartridge and the membrane removes the dissolved solids and organic matter. High quality product water (about 1 ounce per minute) exits the RO housing and goes to the storage tank, or to the postfilter and RO faucet. [. . . ] It is important to test both the treated and untreated water to determine system performance. If the TDS is not within the system' performance guidelines, s replace the prefilter, postfilter and RO membrane cartridges. Chlorine Taste and/or Odor: Replace the prefilter, postfilter and RO membrane cartridges.
