Fidas24 – replace the sample gas filter in the heated sample gas connection
When is it necessary to replace the filter?
The sample gas filter in the heated sample gas connection must
be replaced whenever it is polluted, resulting in the sample gas
flow rate being too low.
Requisite Material
• Sample gas filters with O-rings(Part Number 0768649)
• Allen key 4 mm

CAUTION
Risk of burns
Risk of burns at the heated sample gas connection
(temperature approx. 180 °C)!
• Before working on the heated sample gas connection,
switch off the power supply and allow the sample gas
connection to cool for about 30 minutes.
1. Disconnect the supply of sample gas to the analyzer module!
Power-down the 115 / 230 V AC power supply to the gas
analyzer and heater, as well as the separate 24 V DC supply to
the analyzer module, if applicable!
2. Loosen the three fastening screws
1 and remove the
sample gas filter holder
2 from the sample gas connection
block.
3. Remove the O-rings
3/4 and the polluted sample gas
filter
5 from the sample gas filter holder 2.
4. Insert the new sample gas filter
5 and new O-rings 3/4
into the sample gas filter holder
2.
Note
Always change the O-rings when replacing the sample gas
filter. Contaminated or damaged O-rings impair the seal
integrity of sample gas path; this leads to erroneous
measured values.
5. Place the sample gas filter holder
2 onto the sample gas
connection block and fasten it with the three fastening
screws
1. Only tighten the fastening screws until the
sample gas filter holder is resting on metal. Make sure that
the O-rings
3/4 do not fall out of the sample gas filter
holder in the process.
6. Restore the sample gas supply to the analyzer module.
7. Switch on the power supply.
8. Check the manipulated variables of the internal pressure
regulators for the operational gases, and adjust as necessary
(refer to Fidas24 – Commissioning the gas analyzer on
page 104).
9. Once the warm-up phase is complete, calibrate the gas
analyzer.
