3. Adjust the control’s flow rate. For more information,
see Figure 12.
- Turn the adjustment screw clockwise to raise
the flow rate required to activate the switch.
- Turn the adjustment screw counterclockwise
to lower the flow rate required to activate the
switch.
Figure 12: Flow Rate Adjustment
Note: Do not lower the flow rate required
to activate the switch, unless the flow rate
required to activate the switch is above the
factory-set flow rate.
4. Replace the enclosure cover and tighten the cover
screws with 12 in•lb of torque.
To verify that the flow rate is set above the factory
minimum, depress the main lever multiple times. For
more information on the main lever, see Figure 13.
• If the lever clicks every time when returning to the
original position, then the control’s flow rate may be
set at or above the factory-set minimum value.
• If the lever fails to click every time when returning to
the original position, then the control’s flow rate is set
below the factory-set minimum value.
Turn the adjustment screw clockwise to raise the flow rate
required to activate the switch. See Figure 12.
