G. Installing the Venturi Injector
(continued)
The next step involves the tubing going from the ozone power box to the venturi manifold.
Take the 8' long ¼” reinforced vinyl hose and size it out the amount needed to go from the ozone unit
mounted on the wall going to the installed venturi manifold. You will be adding the two Kynar check
valves included with the package in-line using the nylon hose clamps to mount. The check valves are
precautionary, we strongly recommend using check valves in case of the unlikely failure of the
venturi; the main part of the manifold. This will prevent water from entering the Ozone unit with two
backup check valves in place.
IT IS IMPORTANT THAT YOU INSTALL THE KYNAR CHECK VALVES WHERE AIR FLOW IS
ALLOWED TOWARD THE INJECTOR. AIR DIRECTION CAN BE VISUALLY TESTED BY A SMALL
ARROW ON THE CHECK VALVE ITSELF. IF INSTALLED CORRECTLY, YOU WILL SEE AIR
BUBBLES ENTER THE ¾” CLEAR PVC PIPE.
THESE KYNAR CHECK VALVES AND TUBING WILL WEAR OUT OVER TIME AND YEARLY
REPLACEMENT IS STRONGLY RECOMMENDED. SEE SECTION K OF THIS MANUAL FOR
DETAILS.
DO NOT SUCK ON THE ¼” ID TUBING WHEN CONNECTED TO THE OZONE SYSTEM.
DO NOT LOOK DIRECTLY AT THE OZONE BULB EXPOSED OUT OF THE METAL ENCLOSURE
OR RISK SERIOUS INJURY .
Cut the hose at the areas (depicted to the left) to add the Kynar check valves. These location should
be within 6” of the ozone output coming from the
OzoneMAX
connector and 6” of the venturi manifold
input connector. Add the Kynar check valves in-line in both locations. Connect one end of the hose
to the
OzoneMAX
output connector and the other end to the venturi input connector on the manifold
assembly.

H. Starting the System / Setting the Ball Valve
Once everything has been connected, turn on the power to the ozone unit. Make sure all the
connections are complete and tight.
The next step is critical to the performance of the
OzoneMAX
.
The ball valve will need to the properly adjusted to maximize ozone output into the water. Adjust it
with the pool pump set to the lowest pump speed so that you will see a “frothing” effect in the clear
view window of the manifold assembly. This will appear to be very tiny milk-like bubbles. You will
also be able to hear a noise at the venturi injector and visually see some small bubble action coming
out of the closest return line (and possible other) in the pool.
