3. Relieve water pressure on ACLARUS System by draining the ozone system.
4. Carefully remove the braided hose attached to the Mazzei.
5. Remove Mazzei from Aclarus system.

Servicing and Replacing the Ozone Mixing Pump
4
The mixing pump mixes and recalculates water for introduction and saturation of ozone
in water. The pump generally fails for two reasons:

Running for extended period of time without required water supply.

Supply pressure is below normal or insufficient water supply.
Pump failure leads to these problems:

No water treatment because of improper mixing and saturation of ozone in
the water column.

Leaking seals caused by wear from sand or particulate in the water.

Motor breakdown from faulty part or operating pump with insufficient water
supply.
