Uv Lamp Replacement & Quartz Tube Maintenance - Delta UV EA Serie Installations- Und Wartungshandbuch

G. UV LAMP REPLACEMENT & QUARTZ TUBE MAINTENANCE
The High Output UV bulb in your DELTA UV unit is a useful life of approximately 13 000 hours of operation
(except in the case of repeated lightings where its lifespan could be lower).
The replacement of lamp after 13 000 hours is obligatory.
The quartz tube should be removed, inspected and cleaned from the reactor every year and at each replacement
of lamp.
Reminder: Do not touch the UV bulb glass with your bare hands.
That can shorten its life. Grasp the bulb on the white ceramic prong end
cotton cloth or clean cotton gloves to handle the UV bulb. (If you have touched the bulb with
your bare hands, you must wipe the bulb glass off with spirit vinegar using a clean soft
cotton cloth)
