Description The Corona Discharge ozone generator described in this manual is designed to provide the benefits of ozone gas in an environmentally safe and effective manner. The high quality, specially engineered components ensure efficient ozone output and reliable performance. 1D. Accessories & Optional Equipment 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 1B.
HECD–65 & HECD–130 Installation & Operations Manual NOTE: The ozone gas supply line must have a back flow prevention device (such as a check valve) installed between the ozone generator and the point of injection to prevent water from backing up into the generator system. 5. Electrical Connection: Connect input power and ground to the main circuit breaker and din rail terminal located on the inside of the field connection panel (See Figure 1).
HECD–65 & HECD–130 Installation & Operations Manual 9. Oxygen Concentration Sensor: This device is located in the oxygen stream inside the oxygen sensor enclosure and supplies the PLC with an analog signal proportional to oxygen concentration rate. If oxygen concentration falls below 80% the PLC initiates system shutdown and displays a fault message on the interface panel. 10. Ambient Air Temperature Limit Switch: This limit switch is located on the lower right hand corner of the enclosure.

End Cap: Machined cap provides end sealing for the CD Cell and vertical electrode support. Specialized conical springs in the cap cradle the glass tubes and center the end within the ground tubes. 5. Gaskets and Centering Disks: Die-cut gaskets provide the seal between end housings and the water jacket.
HECD–65 & HECD–130 Installation & Operations Manual 3F-3. LED indicators 1. LED indicators serve as status indicators. LED On System is in Startup mode. Open isolation valve in ozone supply line if so equipped. 2. Start cooling water and verify flow. 3. Verify that all sensor circuits are properly connected. 4. Toggle main circuit breaker to the “ON” position. Close the door. Off System is in Shutdown mode NOTE: Door must be closed for the system to operate. On System is in Standby mode.
HECD–65 & HECD–130 Installation & Operations Manual 1. Press the F1 button on the OIP to immediately halt ozone production. Air preparation system will remain on for an additional 30 seconds, and an internal 60 second timer will begin. This timer will delay any subsequent startup by any of the remaining 60 seconds to allow compressors to vent excess pressure. 2. If desired, turn off the process water circulation pump to deactivate the flow switch. 3.
HECD–65 & HECD–130 Installation & Operations Manual Every Three Months (45 Min.) 1. Perform normal monthly maintenance. 2. Visually inspect cooling fans and filter. Clean filters as required. 3. Inspect oxygen concentrators for proper operation. Ensure that flow rates and pressures are normal. Log hours (max of 10,000 hours till rebuild of compressor is necessary.) 4. Check oxygen plumbing for evidence of chafing. Repair as needed. 5. Test all PLC safety interlocks.
HECD–65 & HECD–130 Installation & Operations Manual 1. Clean water jacket ground tubes by swabbing the inside of the tubes with an alcohol soaked, clean, lint free cloth. 2. Clean electrodes using an alcohol soaked, clean, lint free cloth. 3. Install new zinc anodes using Teflon® tape on threads to insure a watertight seal. 4. Install end cap. Insure the gasket is properly seated in the recessed groove on the water jacket end plate, and that all springs are free from binding. Torque screws to 25 in-lbs. 5.

Replace the switch. Symptom: Low coolant flow is displayed on OIP 1. Cooling water flow sensor is not registering flow. a. Water is not properly flowing past the flow sensor. b. Check wire connections from the flow switch to the control system. c. Faulty flow sensor. Replace the sensor.
HECD–65 & HECD–130 Installation & Operations Manual b. Flowmeter is set for too little flow. Adjust the flowmeter to the required flow and check the injection point for sufficient flow. 2. Loose connection orbroken wire in the Interlock Circuitry: a. Check wiring from the vacuum limit switch to the Control System. Symptom: High coolant temperature is displayed on OIP. 1. Ozone generator cooling system is not working: a. Check for proper water flow. b. Check for high water inlet temperature. 2.

HECD–65 & HECD–130 Installation & Operations Manual OZONE Material Safety Data Sheet SECTION I: MATERIAL IDENTIFICATION IDENTITY: OZONE (Gaseous) FORMULA: O3 ISSUED: February, 1992 REVISED: March, 2009 Description (origin/uses): Occurs in atmosphere from UV light action on oxygen at high altitude. Commercially obtained by passing air between electrodes carrying a high voltage alternating current. Also found as a by-product in welding areas, high voltage equipment, or UV radiation.
HECD–65 & HECD–130 Installation & Operations Manual SECTION VI: HEALTH HAZARD DATA Carcinogenicity: Ozone is not listed as a carcinogen by the NTP, IARC, or OSHA. Primary Entry: Inhalation Target Organs: Respiratory system, eyes, blood. Summary of Risks: There is no true threshold limit and so no exposure (regardless of how small) is theoretically without effect from ozone’s strong oxidative ability.
