13 Service and Maintenance

The 6000TOCi Sensor is designed to minimize service and maintenance. There are
virtually no moving mechanical components, therefore normal operating wear and tear is
minimal. This reduces the amount of consumable components as well as the amount of
time needed to maintain the sensor. Listed below are instructions on how to perform
simple periodic maintenance, which includes UV Lamp change (every 4500 hours of
operation), filter replacement (typically every 6 months), and general cleaning.
UV Lamp Replacement
WARNING: UV RADIATION HAZARD
Apply power to UV lamp only when installed in housing in accordance with
operation manual. DO NOT remove UV lamp from housing unless power is off.
Always protect eyes and skin from direct exposure to UV light.
METTLER TOLEDO Thornton recommends replacement of the UV lamp inside the 6000TOCi
Sensor after 4500 hours of operation, or 6 months of continuous use, not to exceed one year.
This is a simple procedure that requires only a few minutes to complete. The following steps
explain the proper procedure for the UV lamp replacement. Refer to the illustration below.
