ozonator green lights are on but there is not ozone output there is just air coming out from system

The cause could be a loss of continuity in the external loop. When the external loop loses continuity, the main power and cooling fans stay on (green lights remain), but ozone output stops. This interrupts ozone production and turns off the “Ozone Output” LEDs, even though the unit appears powered.

Page 2: Ozone Generator
ClearWater Tech ozone systems are designed for safe, effective use in a variety of water treatment applications. The CD1500P, and CD2000P ozone generators have been tested and certified by the Water Quality Association according to NSF/ANSI 50. Each complete, integrated system may include the following components required for reliable, efficient ozone production and can be divided into four general segments: •...
Page 3 Theory of Operation/Product Description (continued) Depending on the application, the ClearWater Tech ozone generator may be interlocked with an ORP controller, PPM controller, pressure switch, timer or circulation pump. Other safety features are also built in, including thermal protection. Ozone Injection/Contacting The ozone injector serves two purposes: One, it creates the vacuum required to safely draw the ozone gas from the ozone generator and two, it provides a means by which the ozone gas can become...
Page 4: Safety Warnings
SAFETY INFORMATION CHAPTER 2 SAFETY WARNINGS Two aspects of ClearWater Tech ozone generators represent potential dangers – ozone gas and high voltage electricity. OZONE GAS - WARNING: HIGH CONCENTRATIONS OF OZONE GAS ARE DANGEROUS TO HUMANS. LOW CONCENTRATIONS CAN CAUSE IRRITATION TO THE EYES, THROAT AND RESPIRATORY SYSTEM.
Page 5: Important Safety Instructions
IMPORTANT SAFETY INSTRUCTIONS When installing and using this electrical equipment, basic safety precautions should always be followed, including the following: READ AND FOLLOW ALL INSTRUCTIONS. SAVE THESE INSTRUCTIONS. All electrical connections should be made by a licensed, qualified electrician. Before attempting any electrical connections, be sure all power is off at the main circuit breaker. Install all electrical equipment at least five feet from any open body of water using non-metallic plumbing.
Page 6: Equipment Placement
INSTALLATION PROCEDURES - Getting Started CHAPTER 3 Unpacking Compare the ozone system equipment received to the packing list provided. Before beginning any installation procedures, thoroughly inspect all components for damage. If damage is noticed, promptly notify the freight carrier and request an on-site inspection. Inspect all packing materials for small parts before discarding.
Page 7 INSTALLATION PROCEDURES – Plumbing CHAPTER 4 The ozone system should be plumbed using either a sidestream or full flow configuration. The sidestream loop method takes a portion of the water from the main flow (see Figure 4-1) and diverts it into a sidestream downstream of the filter (if so equipped). Ozone is introduced into the sidestream water and is allowed contact time with the water before it is returned to the main flow at a point downstream of all other equipment (heaters, solar panels, etc., if so equipped) in the circulation system.

Step 8: Install the contact vessel venting system into the top of the vessel. If using the ClearWater Tech contact column, the vent kit supplied includes fittings, a control valve and Teflon®...

Page 10: Installation Procedures - Electrical
“THIS CONNECTION IS A DRY CONTACT ONLY, DO NOT APPLY VOLTAGE”. Step 4: Ozone Output Control: The CD1500P and CD2000P ozone generators are equipped with two options for controlling the ozone output. The first option is a manual 0-100% ozone output control and the second is a remote 4-20mA control signal.
Page 11 Electrical (continued) Step 1: Mount the 4-20mA controller to a suitable vertical surface according to the installation manual supplied with the controller. Step 2: Wire the #22 AWG orange ‘positive’ (+) lead from the ozone generator to the 4-20mA controller according to the manual supplied with the controller.
Page 12 INSTALLATION PROCEDURES – Pneumatic CHAPTER 6 This section outlines the steps required to complete the enriched air (90% +/- 3% oxygen purity at -100˚F dew ozone system pneumatic hook-ups. system point). The air is drawn from the ozone generator (where components include the air preparation system, ozone ozone is produced from the oxygen in the air stream) and generator, vacuum break, and ozone injector manifold...
Page 13 Pneumatic (continued) Hook-Ups: Ozone generator-to-vacuum break & vacuum break-to-injector manifold The ClearWater Tech vacuum break provides a positive atmospheric “break” between the ozone injector manifold and the ozone generator, preventing water from flowing back into the ozone generator should the venturi check valve fail. Under normal operating conditions, the vacuum break's flapper valve (see Figure 6-3) is closed, allowing the vacuum created by the venturi to draw the output gas from the ozone generator.
Page 14 START-UP & CALIBRATION CHAPTER 7 The previous sections of this manual have involved comparatively static procedures – making electrical and pneumatic connections, fitting pipe, etc. This section involves the dynamic process of starting up and balancing the components of the ozone system, including initiating water flow, making air and water flow adjustments, etc.

Page 16: Maintenance
MAINTENANCE CHAPTER 8 Maintenance of the ozone system is critical to its longevity and operating efficiency. While all system components are built to provide years of reliable service with minimum maintenance, following the procedures outlined below is strongly recommended. All maintenance procedures have been segmented by interval: daily, monthly, semi-annual and annual. Daily procedures involve quick, visual checks for changes in normal operating conditions.
Page 17 Maintenance (continued) • Cover Filter: Check the cover filter element mounted on the side of the air preparation system and clean as required. Operating conditions in the equipment area will dictate the frequency required for this procedure. Remove the filter element and clean with soap and water, drying them completely before re-installing. Ozone Generator •...
Page 18 Unplug the electrical connections from the drive module. Step 3: Remove the 4-20mA control board with mounting bracket from the reaction chamber of the CD1500P. Step 4: Disconnect tubing connections from the fittings on both ends of the reaction chamber.
Page 19 Maintenance (continued) Step 10: With contact brush attached, remove the brush adapter nut from the high voltage end cap. Step 11: Inspect the dielectric, end caps and cathode for breakage, corrosion or debris. Clean and/or replace parts as necessary. If cleaning and/or parts replacement is not required, re-assemble the reaction chamber per the instructions below.
Page 20 Maintenance (continued) Vacuum Break • Cleaning: Disconnect ozone delivery lines. Remove the vacuum break from mounting clamps. Disconnect the overflow tube from flapper valve, open flapper and clean the seat with a soft cloth. Remove riser tube threaded fitting and flush riser tube with water. Re-assemble and re-install vacuum break, making sure to add water to correct level (see Figure 6-3).
