3. OZONE INSTALLATION PROCEDURE

A bypass must first be created by installing a reducer tee or inlet ring after the last fitting in the water treatment
equipment (e.g., filter, heat exchanger if any). This bypass is used to split off some of the recirculation water being treated
(see Figures 2 and 3).
The water used for ozonation is obtained via a medium-pressure recirculation centrifugal pump, with various models
available for the various models ozone generators, as indicated in Table 1:

This water is then pumped through a 1" venturi to mix and disperse the ozonated air.
The supply and return diameter of the 70/5 (07946), 70/7 (07947) and 120/7 (07948) pumps are listed in Table 2.

Another bypass (see Figures 2 and 3) is installed after the pump. This bypass is composed of a 100% Kynar venturi with
a thread pitch of about 1". It is also equipped with a ball valve of diameter 32 mm and a pressure gauge to indicate the
inlet pressure for the venturi.
The function of the second bypass is to obtain a pressure of 3 to 4 kg/cm
outlet of the CM 70/5, CM 70/7 or CM 120/7 pump (see Figure 4).
The inlet pressure for the venturi must be 3 to 4 bar, in order to take in sufficient ozonated air and mix it with the water
flowing through the venturi.
