Chapter 7 Parts Replacement - Ametek Dycor CG1100 Series User Manual

PARTS REPLACEMENT
The operations in this chapter should be performed only by quali-
fied service personnel. There are no operator-serviceable components
inside the CG1100, and an operator should never open the cover of the
analyzer.
This appendix shows you how to replace system parts and is divided into
the following sections:
• Cell Assembly Replacement
• Thermocouple Replacement
• Furnace Replacement
• Board Replacement
• Flow Meter Replacement
Follow these precautions when working on the sensor:
•
Disconnect the power source from the analyzer when servicing sys-
tem components. High voltages are present inside the analyzer when
power is applied.
•
Always use a backup wrench when working on sensor plumbing. This
helps to prevent damaging welds and distorting sensor plumbing.
The furnace is hot, even after power has been disconnected from the
analyzer. Use caution and wear appropriate gloves if removing the
furnace insulation cover to access the furnace.
