5 Ref.: Ozone generator-AstralPool-gb-R11
Once the water is mixed with the ozonated air, it returns to the general circuit for treatment of the pool water.
A mechanical system is positioned between the venturi and the
Ozone Generator
to ensure that water does not return to
the ozone generator. This system is known as the
check valve safety kit (see Figure 5)
, and is composed of a check
valve and small cup which collects the water until it reaches the indicated level (about 350 mm of water gauge).
The kit operating principle is based on the differences between the liquid-gas densities, which prevents any water from the
venturi from flowing directly to the ozone generator by diverting it to the cup. The minimum height between the cup and the
tee must be about 1,700 mm.
The ozonated air outlet marked “out” is connected to the safety kit using 6*8 mm Teflon tubing, and from there to the
venturi.
