Model 200E Instruction Manual
The thermo-electric cooler needs to be mounted flat to the heat sink. If there is
any significant gap, the TEC might burn out. Make sure to apply heat sink paste
before mounting it and tighten the screws evenly and cross-wise.
• Re-insert the TEC subassembly in reverse order. Make sure that the O-ring is placed
properly and the assembly is tightened evenly.
• Re-insert the PMT/HVPS subassembly in reverse order and don't forget the gasket
between HVPS and PMT. Use new plastic screws to mount the PMT assembly on the
PMT cold block.
• Insert the LED and thermistor into the cold block, insert new drying packages and
carefully replace the end plate by making sure that the O-ring is properly in place.
Improperly placed O-rings will cause leaks, which – in turn – cause moisture to
condense on the inside of the cooler and likely cause a short in the HVPS.
• Reconnect the cables and the reaction cell (evenly tighten these screws), replace the
sensor assembly into the chassis and fasten with four screws and washers.
• Reconnect all electrical and pneumatic connections, leak check the system and
power up the analyzer.
• Verify the basic operation of the analyzer using the ETEST and OTEST features or
zero and span gases, then carry out a hardware calibration of the analyzer
(Section 11.6.5) followed by a software calibration.
