maintenance
Check’s and tasks to be
performed on regular intervals

13. 40
Maintenance scheme
Once a week:
• Check the sample and bypass flows in the SCS.
• Check the sample and air pressure .
• When needed check and clean the restrictions
• After adjustment a new calibration is necessary.
Once a month:
• Perform a calibration (application dependant).
• Compare new slope and offset with previous.
– Check for 1-2 % O2 at maximum range
• Replace filters if needed.
• Check calibration gas bottle pressures
.

14. 41
Once a year
• Clean the mixing chamber.
• Clean the flow meters with iso propanol.
• Cleaning of the gas- and air orifice with iso propanol. Replace Teflon ferrules.
• Remove the zirconium cell from the holder. Check the cell and replace if
needed.
• Remove the cell holder from the oven and add one NiCr grid.
• Clean the flame arrestors.
• Replace filters in air stations and sample filter.
• Check outlet of the oven for any deposit or blocking.
• Leak check the sample system.
• Check the analog and digital in- and outputs.
• Check air purge unit. Adjust purge pressure between 7 en 10 mbarg ( zone 2)
• Check the calibration gasses and check the correct values.
• Allow to stabilize and calibrate the analyzer.
• Check residual oxygen >1% at maximum wobbe-index value.
• Note critical settings (offset, slope).

15. 42
Once a Year (options)
– Pump: replace membrane and valves.
– Fastloop filter: replace filters, support pads and o-
rings
– Sg cell: compare frequencies, if necessary clean
Once every Three years
– Perform yearly maintenance but now:
• Remove used NiCr grids from sample cell holder
• Replace Zirconium Cell
• Replace thermocouple of oven

Insertion NiCr catalyst screens
Folded around the tube
12mm tubing
• Let the oven cool down!
• Unscrew nut at the back of the oven.
• Remove the signal clips from the cell.
• Unscrew the coupling at front of the oven.
• Remove bolts holding oven bracket.
• Pull forward the oven and release it.
• Unscrew the elbow coupling at the inlet.
• Pull the cell holder out of the oven.
• Unscrew the O
2
-cell from holder by using two
wrenches.
• Clean the cell holder.
• Insert new NiCr screens using a piece of 12mm
tubing. Push in the screens and push them backwards
with 12 mm tubing.
• Place a new seal ring over the O
2
-cell and screw
them back in cell holder. Tighten.
• Place holder with cell back in the oven.
• Place one turn graphite tape on the end thread of the
cell holder.
• Clean the thread of the elbow and re-install the elbow.
• Re-install the complete oven.

18. 45
Zirconium cell
• Use the wrenches (size 22 mm) only on the cell holder and the small
nut.
• Check Zirconium cell for any damage.
• Use a new seal ring each time when reinstalling the cell.
