5. Disconnect the tube feeding the membrane (the tube going to the single fitting on the membrane
housing cap). If unsure how to disconnect the quick connect fittings, refer to the section on quick
connect near the beginning of the manual.
6. Remove the membrane housing cap (when looking at the fitting on the cap it will turn
counterclockwise to loosen).
7. Remove the membrane from the housing. A pair of needle nosed pliers may be needed to grip the
end of the membrane. To remove, gently pull with a twisting motion and the membrane should slide
out.
8. Lubricate the O-rings on the membrane with a silicon based lubricant (vegetable oil may be used if
silicon lubricant is not available), and push back into the housing.
9. Lubricate the O-ring on the membrane housing (some housings have 2) and screw the membrane
housing cap back onto the housing.
10. Push the tubing back into the fitting on the membrane cap.
11. If the filters need changed, now is a good time to do so, since the system is turned off.
12. If the system was unhooked to change the filters, hook it back up now. Open the angle ball valve or
feed water ball valve on the feed water line, and open the tank ball valve.
13. Open the faucet, and tilt the system back and forth and side to side to help work the air out of the
lines.
14. Allow the system some time to start producing water from the faucet, depending on the system and
water pressure this may take up to 30 minutes. Once you are getting a steady flow of water (anything
from a steady drip to a small stream, depending on membrane size and water pressure), shut the
faucet off.
15. Allow the system to fill the tank. Depending on the system and water pressure, this can take
anywhere from 1 - 5 hours.
16. Once the tank has filled, open the faucet, allowing all the water to drain until flow from the faucet is
down to the slow drip or stream seen in step 14. This flushes the system, cleaning the membrane
and preparing it for use.
17. Repeat steps 15-16 at least once to ensure thorough flushing of the new filters.
18. Your membrane is now changed and the system is ready to use again.
O-rings:
The filter housings on the system utilize O-rings (black rubber washers, located in a grove right below
the threads on the housing) to seal themselves. To prevent leaks it is recommended to check the O-
rings every time the housings are opened. Ensure there are no nicks, kinks, or gouges in the O-ring. If
damage is found, replace before continuing, otherwise, use a silicon based lubricant (vegetable oil can
be used if no silicone lubricant is available) and lubricate the O-ring before replacing the housing. DO
NOT USE VASELINE! This will damage the o-rings and void any warranty on the system. We are
not responsible for any damaged caused by using Vaseline or other petroleum lubricants. To
ensure a good seal and minimize any possibility of leaks, it is recommended you replace your O-rings
periodically, usually every 1-2 years.
System Sanitization:
Important Note: Reverse Osmosis water purification systems remove most contaminates in drinking
water, however there is no guarantee on the quality of the final product. In addition to that, it is important
that you are aware that bacteria can grow within your RO system, even in homes with no known
bacteria problems, and thus we recommend using this sanitization procedure at least one a year to
prevent and eliminate any bacteria growth. If using on a water supply that has a known bacteria
problem, more frequent sanitization may be necessary. If your system has a UV filter this will eliminate
bacteria in your final product water, however, the UV filter is one of the last stages, so the majority of
the water in your system may still contain bacteria. The bacteria still has the opportunity to grow in your
