Start-Up; Shutdown - Universal Analyzers 500 series User Manual

Start-Up

Apply power to the Universal Analyzers 500 Series Thermoelectric Gas Cooler. The indicated temperature will start to
drop immediately. It should be below the over-temperature set point in approximately four minutes and the "COOL" green
LED lamp should light. When the temperature reaches the control point (set at 5°C), the rate at which the temperature
drops will be reduced. It will stabilize between 4° and 5°C.
Start the sample gas flow. Water should be observed to be removed from the bottom of the heat exchanger when steady
state conditions are established.
If moisture sensors are installed, the (DRY) light should remain on as dry gas is transported to the analyzer(s). Turn on the
analyzer(s) and calibrate as required.

Shutdown

Stop sample gas flow to the Universal Analyzers 500 Series Thermoelectric Gas Cooler by turning off the sample pump.
Allow the drain pump to run for several minutes to remove any remaining condensate from the heat exchangers. After all
condensate has been drained, turn off power to the cooler.
