Hi Flow Sampler Maintenance

Instruction 0055-9017

Figure 5-8. Flow Rate Validation Graph

5. With a fully charged battery pack, the measured flow rate should be

greater than 9 cfm. If not, perform the following (see Figures 5-9

and 5-10):

 Clean the gas sample inlet screen.

 Ensure that the exhaust port is not obstructed.

 Remove the unit’s cover and ensure that the high- and low-

sampling point hoses are properly connected between the flow-

measurement tube and their corresponding solenoid valves, and

that these hoses are not pinched or kinked.

 Ensure that no obstruction is present inside the flow-

measurement tube.

 If none of the above solves the problem, return the unit to your

nearest Bacharach Service Center for evaluation.
