2. Ambient temperature range : 20º F to 85º F Ambient temperature range : 20º F to 85º F - If temperature constantly exceeds 100º F, additional air cooling must be provided Relative Humidity : 75% max. Relative Humidity : 75% max. Unit energized - constant Unit energized - constant (plugged into a non-switched outlet) (plugged into a non-switched outlet) Air flow through dryer : 10 hours max. Air flow through dryer : 10 hours max. SCFH - determined by ozone SCFH - determined by ozone generator used generator used *Equipment: AD40, CD10/AD, M15/AD, CD15/AD Normal Operating Parameters Air Preparation - Heat Regenerative Dry Air

3. Normal Operating Parameters Air Preparation - Oxygen Concentrator n Ambient Temperature range : 20ºF to 85º F 20ºF to 85º F n Relative Humidity : 90% max. n SCFH - determined by ozone generator used. Set to atmospheric generator used. Set to atmospheric pressure pressure n Main power - switch(es) must be on when vacuum is drawn on system on when vacuum is drawn on system (if so equipped)

4. Normal Operating Parameters Vacuum Operated Ozone Generator n SCFH: Determined by ozone generator used – 4 SCFH per 1” cell – 7 SCFH per 2” cell n Vacuum : -3 in.Hg. to -8 in.Hg. (-5 in.Hg. optimum) (-5 in.Hg. optimum) n Ambient temperature range : 20º F to 85º F 20º F to 85º F n Ozone output (HO units): 0 - 100% set by customer 0 - 100% set by customer

5. Normal Operating Parameters Pressure Operated Ozone Generator n SCFH: Determined by ozone generator used – 6 SCFH per cell n Pressure : 9 to 12 psi (10 psi optimum) n Ambient temperature range : 20º F to 85º F 20º F to 85º F n Ozone output: 0 - 100% set by customer 0 - 100% set by customer

6. Daily Procedures 1. Air Preparation – Indicator Cartridge - inspect desiccant (blue & white) desiccant (blue & white) – SCFH - Standard Cubic Feet Per Hour NOTE: Amount will be less if reading is not at atmospheric pressure. NOTE: Amount will be less if reading is not at atmospheric pressure. 2. Ozone Generator – – Indicator lights - main power & operation indicators – SCFH - Standard Cubic Feet Per Hour – Vacuum -3in.Hg. To -8in. Hg. (-5in.Hg. optimum) NOTE: For – Pressure - 9 to 12 psi (10 psi optimum). NOTE: For pressure operated ozone generators only. pressure operated ozone generators only. Maintenance Schedule

7. Daily Procedures 3. Vacuum Break –Water level - above flapper check 4. Injector Manifold – Check valve - inspect delivery line for water 5. Ozone Destruct System – Water trap - check water level, no more than half full – Destruct unit - main power, warm to the touch NOTE: This unit should not see water NOTE: This unit should not see water Maintenance Schedule

8. Maintenance Schedule Monthly Procedures 2. Ozone Generator – Drive module power - check L.E.D.’s – Cooling fan operation – Cooling fan filters - clean 3. Booster Pump(s) – – Strainer baskets - clean 1. Air Preparation Cooling fan operation – Cooling fan operation – Enclosure Filter(s) - clean

9. Maintenance Schedule Semi-Annual Procedures 1. Air Preparation –Compressor air inlet filter(s) - recommended replacement every 4000 hours 41

10. Maintenance Schedule Annual Procedures 1. Air Preparation – Enclosure filter(s) - replace – Compressors - recommended rebuild every 5,000-12,000 hours every 5,000-12,000 hours 2. Ozone Generator – – Cooling fan filter(s) - replace – Inline filter - replace (cabinets in filter bowl) – Solenoid valve(s) - rebuild (cabinets only) – Reaction chambers - clean, rebuild as required

11. Maintenance Schedule Annual Procedures 3. Vacuum Break – Clean - disconnect & rinse thoroughly 4. Injector Manifold – Check valve- replace 5. Contact Vessels – – Column (only) - clean diffuser slots, rinse thoroughly, replace gasket 6. Ozone Destruct System – – Off gas vent - clean, soak in 50/50 solution of water and muriatic acid for 24 hours. – Ozone destruct - replace catalyst (as required)

12. Common Problems Air Preparation - Heat Regenerative Air Preparation - Heat Regenerative Unit not supplied continuous power – Unit not supplied continuous power – Excessive air flow – Extreme environmental conditions - humidity, ambient temperature ambient temperature – Indicators desiccant has changed to white & pink - moisture has entered air prep. system moisture has entered air prep. system Air Preparation - Oxygen Concentrator Main power switch bring turned “OFF” during – Main power switch bring turned “OFF” during normal operation normal operation

13. Vacuum Operated Ozone Generator Vacuum Operated Ozone Generator Unit does not stay on - insufficient vacuum – Unit does not stay on - insufficient vacuum – Low Vacuum - hydraulic/pneumatics out of adjustment, hydraulic back pressure, no water in vacuum break hydraulic back pressure, no water in vacuum break – High Vacuum - change in hydraulics – Unit Flooded - Defective check valve, instal vacuum break break – Low air flow/no air flow - air leak, check air prep system system Common Problems

14. Pressure Operated Ozone Generator Unit does not stay on - insufficient pressure – Unit does not stay on - insufficient pressure – Insufficent pressure - adjust needle valve, check for leaks for leaks – Low vacuum at Venturi - hydraulics out of adjustment – High vacuum at Venturi - change in hydraulics – Unit flooded - defective check valve install vacuum break break

15. Common Problems Ozone Injecting and Contacting Ozone Injecting and Contacting Water back flow to vacuum break - replace check valve – Water back flow to vacuum break - replace check valve – Water bubbling in vacuum break - no vacuum, debris on seat of vacuum break check valve on seat of vacuum break check valve – No vacuum at Venturi port - injector hydraulics out of adjustment adjustment
