Maintenance Hi Flow Sampler

Instruction 0055-9017

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.
