Start-Up; Shutdown - Universal Analyzers 1095E Instruction Manual

Start-Up

NOTE: IT IS IMPORTANT THAT THE HEATED PROBE AND HEATED SAMPLE LINE SHOULD BE
AT OPERATING TEMPERATURE BEFORE STARTING THE CHILLER AND SAMPLE PUMP.
Apply power to the sample cooler. Channel 1 temperature should start to drop immediately. It will be below the over-
temperature set points, (10°C), in approximately four minutes and the sample pump should start as the program leaves
the start-up mode and enters run mode. Channel 1 will operate at approximately 4°C.
For Touch-Screen User Interface See Page 8.

Shutdown

Before removing power from the unit, ensure the system has been purged of any potentially hazardous components.
To purge the system, perform the following:
1. Perform a manual blowback operation.
2. If feasible, provide instrument air to the probe via a cal gas line. If not, disconnect the sample line.
3. Allow the system to run for at least 10 minutes.
4. Once purging is complete disconnect and cap the sample outlet tube connections and disconnect power from the unit.
Note: If electrical wires are to be disconnected, follow applicable 'Lock Out/Tag Out' requirements.
