Introduction to Maintenance and Repair
Simple Repairs - Maintenance
The detector is designed for easy repair. The most frequent repairs such as 
lamp change and flow cell change can be done from the front of the detector 
with the detector in place in the system stack. These repairs are described in 
“Maintenance” on page 117 (part of the User Manual and Service Manual).
Exchanging Internal Parts - Repair
Some repairs may require exchange of defective internal parts. Exchange of 
these parts requires removing the detector from the stack, removing the 
covers, and disassembling the detector. The security lever at the power input 
socket prevents that the detector cover is taken off when line power is still 
connected. These repairs are described in “Repairs” in the Service Manual).
