Use the small bladed screwdriver attachment of the supplied toolkit to turn the flow adjust screw. To increase
the flow rate turn clockwise. The span of the flow adjust screw is 12 turns. DO NOT FORCE the flow adjust

Use a suitable flow calibrator (such as a rotameter or Defender primary calibrator) to set the required flow rate,
do not use the built in flow indicator.
