5.4 Replacing the Internal Filters
Three internal filters protect the instrument from being contaminated by
dust and dirt. Replace these filters when they look contaminated. A good
indication that a filter needs replaced is when the instrument’s gas-
response time increases.
5.4.1 Leak-Gas Filter
The leak-gas filter is located between the sampling port on the flow-
measurement tube and its associated solenoid valve on the printed
circuit board. See Figure 5-3.
Equipment Required:
 Medium Phillips Head Screwdriver
 Replacement Filter (P/N 07-1563)
Procedure:
1. Remove cover per Section 5.3.
2. Remove tubing from old filter’s inlet and outlet.
3. Install tubing on new filter, making sure that the filter’s flow arrow
points away from the flow-measurement tube.
4. Replace cover that was removed in Step 1.
