Figure 10: DEL AOP Electro-Mechanical Overview
(AOP 40 Shown)
4A-1. Ozone Module Description
*The DEL AOP is constructed with one (AOP 25) or two (AOP 40) APG2 corona discharge ozone modules. Blue ozone light on
system smart status LEDs indicate ozone modules are operating properly (refer to Figure 8 for a more detailed view).
4A-2. Injector Manifold Description
Water flowing through the injector manifold generates the vacuum that draws ozone into the water. The spring-loaded valve
automatically adjusts for various water flow rates to keep the DEL AOP operating over a wide range of conditions.
4A-3. Ozone Gas Line Description
Gas from the ozone modules is drawn through the ozone gas Line by the injector and into the water. The ozone check valve
(refer to Figure 12) in this line prevents water from migrating back to the ozone modules when the DEL AOP is not running.
4A-4. Ozone Module Air Filter Description
The air entering the ozone modules passes through the air filter (refer to Figure 11) on each module inlet. The filter is held in
place by the rubber filter cap.
