Replace the PDA detector's lamp annually during the prescribed preventive maintenance (PM) or any time it repeatedly fails to light or when the detector fails to calibrate. The system automatically senses the lamp upon installation, and its serial number and installation date are automatically recorded in the Lamp Change Record table.
Note: Waters warrants 2000 hours of lamp life, or one year from date of purchase, whichever comes first.
Warning: To prevent burn injuries, allow the lamp to cool for 30 minutes before removing it. The lamp housing gets extremely hot during operation.
Warning: To avoid eye injury from ultraviolet radiation exposure:
Power-off the detector before changing the lamp.
Wear eye protection that filters ultraviolet light.
Keep the lamp in the housing during operation.
To replace the lamp:
