• Short-term inhalation of high concentrations of ozone WARNING and long term inhalation of low concentrations of ozone can cause serious harmful physiological effects. DO NOT inhale ozone gas produced by this device. • For your safety, do not store or use gasoline, chemicals or other flammable liquids or vapors near this or any other appliance.
Section 1 General Information 1A. Description The DEL AOP 50 Ozone and UV Sanitizer System described in this manual is designed to provide the benefits of ozonated and UV treated water in an environmentally safe and effective manner. The high quality, specially engineered components ensure efficient water sanitation output and reliable performance.
2B. Location The DEL AOP 50 unit is designed for floor mounting. Locate the unit in a clean, protected area, either indoors or outdoors (preferably out of direct sunlight). If possible, locate the unit out of reach of sprinklers or drainage spouts.
2D. Electrical 2D-1. Main Power Connect the DEL AOP 50 to the pool timing clock so that the DEL AOP 50 operates simultaneously with the pool pump. The DEL AOP 50 has four available Knockouts for a 1/2” conduit fitting, two on the back and one on each side.
Appendix A. The DEL AOP 50 will come with one half of a union fitting installed on Inlet and Outlet, the other half of the fittings will be located in the DEL AOP 50 parts bag.
To remove the bubbles from the flow, an accessory Mixing Degas Vessel, or MDV, can be installed downstream of the DEL AOP 50. The MDV-100 is designed for use with the DEL AOP 50 and is recommended on indoor, covered, or vinyl-lined pools.
3B. Normal Operation Indicator Lights: The DEL AOP 50 has two external indicator lights, red and green, on its left side. When the DEL AOP 50 has power, the green Power Light will illuminate. The red Flow Indicator may be on momentarily.
4A-2. Ultraviolet Lamps There are two lamps in the UV Reactor of the DEL AOP 50. If the UV Lamp Access Panel is removed while the unit is running, a slight glow can be seen near the top of the lamps (Refer to Figure 6 for a more detailed view).

Remove the Filter Cap Assembly from the right tube fitting of the Ozone Module. Make sure you keep the Cap, Filter and Orifice together.
Reactor every six (6) months and cleaned if necessary. Figure 6: Ozone Bracket During Ozone Module Service 4D-1 Lamp Removal 1. Locate the UV Lamp Access Panel on the top of the DEL AOP 50, remove the 4 screws with a Phillips head screwdriver, and remove the panel. 2. After allowing adequate time for the lamps to cool, disconnect the Lamp Connectors from Ballast wires.

TURN OFF YOUR PUMP IF YOU HAVE NOT DONE SO. 2. Slowly press the UV Lamp fully past the Lamp Retainer tabs and into the Quartz Tube until it is seated on the Lamp Cushion in the bottom of the tube.
SECTION 6A). Symptom: Green Indicator not lit when pool system is on. 1. No power to the DEL AOP 50 from the Power Source: a. Check circuit breaker at the power distribution box. b. Check for loose connections or wiring breaks in the lines leading to the Terminal Block.

APPENDIX A DEL AOP 50 Installation - Plumbing The DEL AOP 50 works under vacuum. The injector in the DEL AOP 50 draws the ozone/air gas mixture from the ozone cells and mixes it into the water leaving behind some un-dissolved gas bubbles. These bubbles can affect certain pool system components, so care must be taken when installing the DEL AOP 50.
Ozone Manifold and Air Inlet Filters. • Leave the DEL AOP 50 disconnected and run the pool circulation system. Allow fresh air to be pulled through the cells for 10 minutes. • Close or reattach the DEL AOP 50 cover and reconnect power.

APPENDIX C DEL AOP 50 Pressure Drop Characterization NOTE: Tested on simulated recirculation system using a Pentair Intelliflo variable speed pump. No back pressure added. Back pressure will raise the inlet pressure (filter pressure) but reduce the pressure drop slightly. Actual results will vary depending on pump and plumbing variables.
The DEL AOP 50 Quartz Tubes may be cleaned without removing them from the vessel. Ensure that the DEL AOP 50 is isolated from the rest of the pool system with valves at the inlet and outlet (as shown in Figure 3).
