Annual UV Lamp Replacement: The UV lamp has an effective life of 9000 hours of continuous operation, after which it should bereplaced regardless of its apparent condition. As a good maintenance procedure it is recommended that the quartz dome also becleaned at the time of lamp replacement. Hold the lamp and dome by the ends with soft dry gloves or cloth.How to replace the UV Lamp:1. Unplug UV unit from electrical outlet and turn off supply valve before the unit. Open a faucet to depressurize the UV systemand turn off the valve at the UV outlet to isolate UV unit. Wait several minutes for the lamp to cool down.2. Unscrew the ground nut and remove the ground wire (green wire with yellow stripes).3. Loosen the black screw on the lamp connector cover and remove cover from the gland nut.4. Carefully slide UV lamp slightly out of chamber and hold the lamp end with one hand. CAUTION: The lamp end can bevery hot. Gently pull off the connector with your other hand to disconnect the lamp completely. Slowly remove lamp from thedisinfection chamber completely.5. Remove the quartz dome by loosening the gland nut and carefully extracting from the unit. Remove dome absolutelyvertically from its position until the other end comes out. CAUTION: If you bend the dome mid-way, it can break easily andpieces of quartz can fall into the UV chamber. Do not lose the spring.6. Remove & discard used dome "O" ring. Clean dome gently with a vinegar solution or a household scale-removal product.7. Using a small pointed tool carefully take the gland-nut "O" ring out of the gland nut. Take care not to scratch the gland nut.8. A dome "O" ring (thicker) and gland nut "O" ring (thinner) are included with the replacement lamp. Slide gland nut "O" ringinto the internal groove of the gland nut.9. Replace dome "O" ring on to quartz dome about 1" from the open end. Gently push the quartz dome into the gland nut untilit touches the top. Carefully replace quartz dome into UV chamber and hand-tighten gland nut.10. Carefully unpack the new lamp and slide into the disinfection chamber. Holding the lamp end, gently lamp connector onto the pins. Slide the lamp connector cover over the gland nut and tighten the black screw. Re-connect ground wire.11. Slowly open supply-valve and valves before and after the UV and check for leaks.12. Depress timer button while reconnecting ballast to electrical outlet and keep the button depressed until the ballast emitsa solid three-second beep. This will re-set the lamp-change-timer to zero and the 3-second beep will confirm that the re-setwas successful.13 Flush water through the UV for 2-3 minutes. The unit is ready for service.Cleaning the Quartz Dome: Some water conditions may require cleaning of the quartz dome more than once a year. To cleanquartz dome, follow the lamp-replacement instructions. NOTE: Do not depress timer-button when reconnecting ballast toelectrical outlet. The green lamp-ON LED will light, followed by three buzzer beeps and three red timer-LED flashes. The quartzdome should be replaced every three years.PROBLEM PROBABLECAUSESOLUTIONBallast is inalarm1.
