To change the membrane:
Note:
The tank will need to be emptied when replacing the
membrane. If you would like to save the water in the tank for use,
follow the instructions below, opening the faucet and collecting
the water from the tank after turning the feed water off.
1.
Turn off the feed water supply. This is done by closing the
angle adapter ball valve. The valve is closed when the handle is
at a 90
°
angle to the tubing (when handle is NOT parallel to
tubing). If saving water from the tank, do so after closing the
valve.
2.
Shut the ball valve on the tank. The valve is closed when the
handle is at a 90
°
angle to the tubing (when the handle is NOT
parallel to the tubing).
3.
Open the faucet to release any remaining pressure.
4.
Pull the system out to where it can be easily worked with. If
the system was installed with enough tubing to do so, simply
pull it out to where it can be worked on. If the system does not
have enough tubing, you will need to disconnect the lines to
pull it out. (When changing the membrane, it helps to have a
towel handy, as some water may leak out.) Make note of which
tube goes where to ensure the system will be hooked up the
same way it was.
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.

fitting that grips the tubing and holds it in place. To remove,
simply hold the collet ring against the fitting and pull the tubing
out. To replace tubing, just push it into the fitting, it will slide in
easily about 1/4” then stop, apply a little more pressure and it will
slip in another 1/8” or so and seal in place.
5.
Familiarize yourself with any purchased upgrade kits. If you
ordered any kits to upgrade your system, read through the
instructions on how to install it, as it is usually easier to install any
upgrades before installing the system.
6.
Check to ensure there are no missing parts. Use the parts
checklist on the following page to make sure all the parts listed
are present. If anything is missing, call us and we will get
replacements out as soon as possible.
7.
Assemble the tools you will need. Depending on where the
system is being installed and the plumbing, the tools needed may
vary. You will need a Phillips head screwdriver, drill, wrenches,
pliers & PTFE tape. You will also need a sharp knife or scissors to
cut the tubing (when cutting tubing, ensure the end is smooth and
straight, this will ensure a good seal and prevent leaks). This list is
just a start, reading through the instructions and determining
where you are installing the system will give you a better idea of
everything needed.
8.
Ensure the following conditions are met:
Feed Water
Condition
Minimum Maximum
Inlet Pressure
40 psi
80 psi
Temperature
40
°
F
100
°
F
pH Level
3
11
TDS Level
0 ppm
2000 ppm
For pressure less than 40psi a booster pump will be required. If
pressure is less than 50psi a booster pump or permeate pump is
recommended. If other conditions are not met contact us for a
solution.
NOTE
: Failure to meet the above conditions will void the
warranty on the system.
Parts Checklist
In addition to the RO system, faucet, storage tank, and UV
transformer (if a UV was ordered), you should have the following
