7.2.4 Manual % dial (when dip switch D is off)

The manual % dial allows the speed of the pump
to be manually adjusted and set by the user.
The speed of the pump may be manually
adjusted anywhere from "Min" to "100 %", but
once set remains fixed at that speed. The "Min"
position on the dial will either be equal to OFF or
15 % depending on the position of dip switch C.
The factory default is 50 %.
Insert power cord from the pump into a properly
grounded 115 V outlet. This will apply power to
the pump/controller.

7.2.5 Performance indicator LEDs

"Power On" (green) indicates that power is
applied.
"% Out" (yellow) indicates the speed of the
pump by flashing at different speeds.
