3.4 Check Valve Replacement
Protecting your ozone generator from water infiltration is vital. Ozone generators will fail
if water is allowed to enter the corona region. Water infiltration can be avoided by proper
installation and maintenance of a Backflow Prevention Device between the ozone generator
ozone outlet and the venturi injector (or diffuser).
We strongly suggest that the check valve is closely inspected as often as possible, such as each
time maintenance of any type is performed. If water is visible between the check valve and the
ozone generator, cracks are visible in the check valve body, or foreign matter has built up on
the internal O-ring, replacement should be performed immediately regardless of elapsed time
since last replacement. Reference figure 4 for check valve detail.
The required replacement schedule is listed below and must be performed on schedule, even if
the check valve appears sound.
Frequency of Replacement:
Every 3 months
To Replace Check Valve
1. Disconnect unit from power source. Allow the ozone generator to clear of ozone gas.
2. Remove tubing from barbed end of the check valve.
3. Trim approximately one inch from the end of each tube, to remove distortion caused by the
hose adapter.
4. Place new check valve assembly in-line, between ozone generator and venturi injector.
Note: Check valve flow direction must point toward venturi.
5. Secure the tubing onto barbs by installing snapper clamps
