5. Press the Program key when all changes have been made.
6. Press the Run key for pump operation.
4.4 Calibration Procedure for Maximum Pump Output in GPH
A 30-second graduated calibration cylinder should be used to perform a draw-down of actual chemical and
including typical system injection pressure to establish the maximum pump output during normal operating
conditions.
Using the pump to fill the cylinder, make sure the K4 Drive/VFD is set to the highest possible speed using the
‘up’ arrow on the keypad. Since there is a short ramp-up time for the pump to reach maximum speed, it is
recommended to over-fill the calibration cylinder for higher accuracy. After filling the calibration column, make
sure the appropriate valves are open to allow the pump to draw from the calibration column only.
4.5 Draw Down Procedure:
At the same time start the pump and the stop watch. If you slightly over-filled the calibration cylinder, start the
pump and then start the watch when the chemical reaches the "0" point on the calibration cylinder.
Once the stopwatch reaches 30 seconds stop the pump.
Review the graduated markings on the calibration cylinder to find out how much liquid was pumped in 30
seconds.
4.6 Programming Guide:
On the K4 Drive/VFD you will go into the program settings section below.
Change Function Codes:
4.00 = 0002
4.01 = Gallons per Hour x 10
4.02 = 0001
This will set your max value on the K4 Drive/VFD display to be your max GPH pumping capacity.
