STARTING THE OZONE SYSTEM
The start-up of the ozone system will depend largely on how the system has
been installed but the following checks should be carried out:
1. Check that the water trap pot and the degasser drain pot, if fitted, have
been filled with water to a level of 25mm from the top of the pots and
that all interconnecting tubing is correctly installed.
2. If the system is fitted with the optional degasser system, check that the
activated carbon filter pot has been charged with gravel and activated
carbon.
3. Disconnect the flexible tubing between the water trap assembly and the
ozone generator.
4. With the main circulation system running, open both system isolating
valves to the flood system, check the system for any signs of wate
leakage and also that the check valve assembly within the water trap
unit has stopped any backflow of water from the injector.
5. Start the booster pump to ensure that suction is achieved at the side
connection of the water trap assembly. The booster pump should be
stopped and re-started several times to ensure that the ball check valve
incorporated in the water trap assembly seals properly and stops any
water backflow from the injector. Once this has been checked, then the
suction connection to the ozone generator can be remade.
6. Switch on the ozone generator (and air dryer) and then re-start the
booster pump. Air should now be drawn through the ozone system.
7. Check the airflow through the ozone generator and set to 12 litres/min.
utilising the booster pump discharge valve to control the air flow through
the ozone generator.
8. If the system is fitted with the degasser system, check that the
automatic air release valve is venting the column properly and
maintaining a near static water level within the column.
9. Check that there is no smell of ozone from the area of the activated
carbon filter pot. If there is, turn off the ozone generator, air dryer i
fitted, and booster pump and carry out the checks in 1 and 2.
10. Check that the system operates correctly under time clock or redo
control if fitted and that if the main circulating pump stops, the ozone
system stops.
11. Check that the booster pump always maintains a flooded suction afte
the main circulating pump has been switched off.
