Welker Inloop Ace Installation, Operation And Maintenance Manual page 13

22. As necessary, adjust the sample volume of the inLoop™ ACE (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.
Once the desired volume is set, the sample volume can be changed at any time externally without removing the inLoop™ ACE
from the fast loop.
Welker can pre-set the sample volume if noted at the time of order.
