Restricted Flow Control Valve:
The manual control valve is used to fi ne tune the fl ow speed of water
when operating at low speeds (velocities less than 1.0 m/sec).
a. Opening Valve
i. Turn the valve counterclockwise. Promotes water fl ow.
b. Close Valve
i. Turn the valve clockwise. Inhibits water fl ow.
1. 1.0 m/s – 7.0 m/s
a. Simply tab the yellow box, input the desired speed, and tap the
check mark to confi rm. For best results, the valve must be
completely open.
2. Less than 1.0 m/s
a. Any inputted value less than 1.0 m/s will set the pump to initially
circulate water at a speed between 1.0 m/s to 1.3 m/s. To drive the
fl ow speed to the desired inputted value, the valve, shown above, must
be used. Once the value is set and the circulating water has stabilized,
partially close the valve to the desired fl ow speed. The machine will
stabilize the fl ow speed to the inputted value. (Note: Setting lower
speeds, such as 0.3 m/s, are imprecise than higher speeds, such as
0.8 m/s).
