14.3 Replacing The Gas Inlet Adapter (Pumped Versions Only)
When you remove the black gas inlet adapter, unscrew it in the same manner as the external filter. When
replacing it, make sure that the arrow on the front points to the triangle on the rubber boot. Perform a
pump stall test to make sure the inlet and the external filter are installed properly so that there are no leaks
in the system.
14.4 Removing/Cleaning/Replacing Sensor Modules
WARNING!
Do not replace sensors in hazardous locations.
All sensors are located inside the sensor compartment in the upper half of the MultiRAE. They are
accessed by removing the cover that is held on by four screws.
1.
Turn off the instrument.
2.
Remove the four screws holding the sensor compartment.
3.
Remove the cover. The sensors are plugged into the slots.
4.
Gently lift out the desired sensor module with your fingers.
5.
Install the replacement sensor. It can only go into its slot one way. The connector inside the
MultiRAE and the indexing guides are good visual indicators of how to set the sensor into
position. Make sure the indexing keys are aligned and that the sensor is seated firmly.
WARNING!
If you are removing a sensor and not replacing it, the slot cannot be left empty. A MultiRAE “dummy”
sensor must be installed in such slot.
