6.1.4 Protection from dust
The gas sampling system must be protected from dust entering the tubes, valves and other
components. In order to achieve this goal, the following measures must be taken:
•
Have the mini D-fend water trap always connected to the module.
•
Clean and dust free working environment during all service procedures.
•
Minimize the times with any open connections in the gas sampling system.
•
Always close the open tube connections of the sampling system when not working on the
module.
•
Remove the protective caps on the gas pump just before assembling it to the module
•
The clothing of the service person must be such that the dust risk is taken into account.
6.1.5 Before disassembly
•
Note the positions of any tubing parts, wires or cables. Mark them if necessary to ensure
that they are re-assembled correctly.
•
Save and set aside all hardware for reassembly.
