3. If applicable, confirm proper heating of the sample supply tubing.
4. Confirm that all sample system shut-off valves are closed.
5. Confirm that the sample bypass and analyzer flow meter control
valves are gently closed (adjustment knob turned clockwise).
Tostartupthefieldpressurereducingstation
1. Confirm that the sample probe isolation valve is closed.
2. Confirm that the pressure regulator at the field pressure reducing
station is closed (adjustment knob turned fully counterclockwise).
3. Slowly open the sample probe process shut-off valve at the sample
supply tap.
4. Slowly open the pressure regulator at the field pressure reducing
station (adjustment knob turned clockwise) and set the pressure
regulator to the specified pressure.
5. Blow sample through the sample transport tubing to flare or safe
vent to ensure that dirt or liquids are in the sample tubing.
6. Reconnect the sample transport tubing and set the pressure or the
regulator to the specified pressure.
Starting up the full-featured sample system
Use the following steps to start up the SS500/SS2000 with a full-featured
sample conditioning system (SCS).
Follow instruction for setting the flow meter control under the
appropriate start up instruction for either the full-featured or
simplified sample system configuration.
Do not overtighten the control valves or damage could occur.
The process sample at the sample tap may be at a high pressure.
Use extreme caution when operating the sample probe isolation
valve and field pressure reducing regulator.
