Maintenance

The following table provides a list of items that need regular maintenance to ensure your product remains in good working condition.

ITEM	ACTION	FREQUENCY	MANUAL SECTION
Internal Particulate Filter	Replace	6 months¹	9.3
UV Lamp	Adjust	As Indicated by ‘Check Lamp’ LED or status output	9.4
UV Lamp	Replace	As required; when adjustment can no longer be performed.	9.5
Sample Pump	Replace	2 years	9.6
Sensor Module Valve	Replace	2 years	9.7
¹ When external sample line pre-filters are used. If pre-filters are not used, internal sample filter should be replaced every month.

¹ These Items are required to maintain full warranty; all other items are strongly recommended.

² A pump rebuild kit is available from Teledyne API's Technical Support including all instructions and required parts

³Replace desiccant bags each time the inspection plate for the sensor assembly is removed.

Applications

Description

The Model 465L UV Photometric Ozone Monitor is an extremely stable analyzer, ideal for critical low-level ppm safety and process applications. Its calibration is NIST traceable and the included pressure and temperature compensation ensure high accuracy under all conditions.

The Model 465L is available in a 19” rack mount or NEMA 4X wall mount enclosure and can be purchased either as a single stream unit or as a multi-channel unit capable of monitoring up to six individual sample streams. The Model 465L has been designed to deliver excellent performance, high reliability and simple operation. Operating parameters can be easily set up in the field using the operator-friendly menu driven software.

Built-in diagnostics provide warning signals in case operating parameters are out of range. Test values can be viewed while the Model 465L is operating. These displays, warnings, and self-diagnostics, along with the modular design, allow maximum uptime. In addition, any function that can be set or monitored from the front panel can be remotely set or viewed through the bi-directional RS-232 port.
