Step 2 Set up - Calibration
Connect your hose and brush to the pump.
5
Turn on the controller by turning the PUMP
FLOWRATE dial clockwise - water needs to be
flowing to the brush.

FLOWRATE
Turn the DEAD END CALIBRATION dial to
maximum (fully clockwise) to let the flow of
MIN MAX
water start.
DEAD END
CALIBRATION
Slowly turn the DEAD END CALIBRATION
dial back down (anti-clockwise) until the
water flow stops. The DE LED will illuminate.
MIN MAX
Turn the DEAD END CALIBRATION dial back up
(clockwise) a little until the water flow re-starts
and remains constant.
MIN MAX
The controller should now be calibrated to your system and we would
expect the dial to point between 12 and 2 O'Clock. However this is
system dependent.
Note: in a properly calibrated system, DE will be detected by the controller
long before PS (pressure switch) is activated by the pump - due to a restriction.
This saves wear on the pressure switch and resumes pump operation
(and working) far more quickly when the flow is started at the pole again (e.g.
pole valve opened, hose kink removed or pole reconnected).

Step 3
To adjust the water flow simply turn the PUMP FLOWRATE dial up
(clockwise) to increase the flow and turn down (anti-clockwise) to
decrease the flow.
Note: the higher the water flow the harder the pump is working
(drawing a higher current). Higher current draw will reduce working
time per battery charge.

Description
If LED is ON then pressure switch has been activated or
motor disconnected.
If activated by a flow restriction in your system then
remove the restriction (e.g. hose kink) to reset the pump
pressure switch and resume pumping.
If LED is ON then a dead end has been detected. If this is
not the case try increasing the Cal value. In dead end the
controller will stop the water flow. If activated by a flow
restriction in your system then remove the restriction
(e.g. hose kink) to resume pumping.
If LED is ON battery voltage is ok.
If the LED is flashing battery voltage is 11.0V or less. The
controller will shutdown the pump to protect your battery
if the voltage falls below 10.5V. Note: permanent damage
to your battery cells can occur below 10.5V.
