13 Service and Maintenance continued
CAUTION: Use of a UV lamp other than those provided by METTLER TOLEDO
Thornton specifically for use with the 6000TOCi Sensor will affect
performance and void the warranty of this product.
1. At the sensor, turn off the UV lamp by pressing the lamp control button (UV lamp
ON LED will turn off). If the LED does not turn off, check that the Sensor Key Lock
is in the off position in the M800. Refer to
function in the operation manual.
2. Once power to the UV lamp is off, remove the UV lamp replacement side access
panel on the left side of the sensor using a Phillips head screwdriver.
3. Disconnect the power cable to the UV lamp.
4. Loosen the black UV lamp holding screw.
5. Slide the cable of the UV lamp through the side opening of the enclosure and gently
slide the UV lamp out of the oxidation chamber assembly (stainless steel cylinder).
Be careful not to let the UV lamp hit the quartz glass coil inside the chamber.
6. Use the gloves supplied with each replacement bulb. Hold the new lamp from the
ends of the lamp. Do not touch the clear glass portion of the bulb. Slide the new
UV lamp into the side opening of the enclosure and into the oxidation chamber
opening until it stops. Do not use excessive force to insert the UV lamp as this may
cause damage to the lamp or the internal components of the oxidation chamber.
7. Tighten the UV lamp holding screw until snug. Do not overtighten.
CAUTION: Do not overtighten holding screw.
8. Feed the power cable through the side opening of the enclosure. Re-connect the
cable to the power connector.
10. After the lamp replacement has been completed, a TOC calibration must be perfor-
med. In addition, a System Suitability Test is recommended for applications where
compliance with Pharmacopeia regulations is necessary.
