Spring V16 HC User guide

Wiring
12V Battery Pump
Fuse 10A
Basic Guide
The Fuse for this unit is a 10A Fuse. Make sure correct fuse is fitted inline, close to the
battery end of the RED (positive) wire. Failure to do so will result in damage to the unit.
Connect the pump controller in accordance with this diagram.
NOTE: only fit the fuse once all connections are made.

Adjust the flow settings carefully. Repeated false dead-end detection
indicates that the Cal value should be increased (less sensitive).
For safety wire through the pump pressure switch. (The pressure
switch can be bypassed if absolutely necessary - the unit will protect
itself under normal conditions.)
This is a WATER PUMP controller: it will not work with air in the system.
Always prime the system before starting work. If air in the system
causes false dead-end detection, increase Cal value until air is removed.
Do not set the Cal value too high. Setting it higher than necessary
places extra strain on both the pump and the controller in a dead
end situation. This can result in damage to both the pump and
your controller.
* Your battery is at risk of permanent damage if you disable low battery cutoff and continue
to use your controller for long periods when the battery voltage has fallen below +10.5V.

Connect your hose and pole + brush to the pump.
Turn on the controller by pressing the power button.
Press up until the display shows 30.
Press and hold the up and enter buttons to calibrate. CAL will be displayed.
To select Auto Cal continue to press the down button until AUt is displayed.
Press the enter button to start. Auto Cal starts from C99.
After several moments the calculated CAL value (e.g. C50) will be displayed
and the controller is ready to use. Press enter to exit calibration.
The CAL value can be adjusted manually by following the same steps and
adjusting the CAL value by pressing the up or down button instead of using AUt.
To enable or disable the low battery cut-off* (that stops your pump when the
battery voltage is below 10.5V) press and hold the down and enter buttons.
Then use the up or down button to select ON or OFF. Press enter to save.
NOTE: ‘ON’ keeps your battery protected.

Set Up - Auto Calibrate

Press up or down to set a suitable flow of water.
Press enter to display the current battery voltage.
Press enter again to return to the current flow rate.
To turn the controller off, press the power button.
Message
An error has occurred while using AutoCal. This will happen when
the motor is not connected or the enter button has been pressed
to cancel it.
Pressure switch has activated or the motor is disconnected.
A dead end has been detected. If this is not the case, try increasing
the calibration value.
This message will start to flash when the battery is low (<11.0V). If
the battery is below 10.5V the pump will be disabled to protect the
battery, unless low battery cutoff is disabled.*
An over current has been detected, the controller has shut down
the pump to protect itself. Lower the flow rate and check the hose
for blockages.
