Verifying The Sample Volume - Welker Inloop Ace Installation, Operation And Maintenance Manual

2.4 Verifying the Sample Volume

Welker recommends the Welker Checkpoint™ Sample Bite Verification Panel for use with this unit.
1. Ensure that the Welker Checkpoint™ Sample Bite Verification Panel has been installed correctly. Refer to the Installation,
Operation, and Maintenance (IOM) Manual for the Checkpoint™ for installation instructions.
2. Using appropriately sized customer-supplied tubing, connect from the sample outlet on the inLoop™ ACE to the
sample inlet on the Checkpoint™ (Figure 2, Figure 3, Figure 4, Figure 5, or Figure 6).
3. Decide how many actuations will be made to verify the sample volume.
Welker recommends a minimum of ten (10) actuations to verify the sample volume.
4. Follow the instructions in the Installation, Operation, and Maintenance (IOM) Manual for the Checkpoint™ to complete
sample volume verification.
5. As necessary, adjust the sample volume (Figure 7).
Loosen the jam nut on the adjustment screw.
To increase the volume, turn the adjustment knob clockwise.
To decrease the volume, turn the adjustment knob counterclockwise.
Tighten the jam nut on the adjusting screw to secure the adjusting screw at the desired volume.
Two (2) full rotations of the adjustment knob is approximately 1 cc.
Ensure that the jam nut is tightened to the fastener seal prior to beginning operation, as the pump will not operate correctly
unless the jam nut is properly tightened. A leak check may be performed to verify that the jam nut has been properly tightened.
