- The 12V Pump Controller can get warm. It is set to turn off at 65ºC.
- Do not block the fan intake or exhaust vent during operation of the 12V Pump Controller.
- Do not touch the inside of the 12V Submersible Pump after it has been running – the motor module gets extremely hot.
- This 12V Submersible Pump is to only be used for groundwater purging/sampling.
- The 12V Pump Controller is water resistant but not waterproof. Do not submerge in water.
- Do not use the 12V Pump Controller near flammable liquids or gases.
- The 12V Submersible Pump is designed to operate when submerged only.
- The Solinst Model 415 12V Controller is only designed to work with the Solinst Model 415 12V Submersible Pump.
12V Submersible Pump Power Supply
The 12V Pump Controller operates from an external 12 volt DC power supply such as a car, truck or marine 12 volt battery that can supply up to 45 amps at maximum draw. The Pump Controller has a 2.3 m (7.5 ft) power cable with connector clips for direct battery connection.
The power cable clips are oversized for use with automotive batteries. The red clip connects to the positive (+) battery terminal, black to negative (-) battery terminal. If the battery is connected with reverse polarity the Controller will not be harmed, but it will NOT operate until the polarity is connected correctly (the LED on the Pump Controller will remain off with reverse polarity).
A circuit breaker reset button is located on the side of the Pump Controller. In the event the amperage exceeds 50 amps, the circuit breaker will trip (button pops out) and turn the Controller off. To reset the breaker, turn the dial to "0" then press the reset button back in to regain operation.
If the Pump is to be powered by a typical 45Ah vehicle battery, start the vehicle and run for 15 minutes to recharge the battery, then restart the vehicle every 15 minutes for 5 minutes to maintain the battery power during sampling.
12V Submersible Pump Operation
- The Pump Controller should always be kept with the dial in the OFF position when it is being attached to a power source or stored.
- The Pump Controller dial is used to adjust the flow of water being discharged. As you increase the dial, so does the Controller's voltage output. This will enable the Pump motor to spin faster, therefore, increasing the flow of water being discharged. To slow the flow of water, turn the dial counter-clockwise.
- When the dial is in the OFF position the Controller will produce 0 volts, in the highest position "10" the Controller will output 25 volts.
- The Controller has a low voltage disconnect at 10 volts as indicated by the slowly flashing yellow light. (However, the Controller can disconnect at a higher voltage if the Pump's current increases, e.g. if the Pump is running at maximum current (20 amps), the battery can disconnect at 11.7 volts.) The Controller will shut off and then turn on every few seconds (pulsate) or the water flow from the Pump will slow if the output voltage on the battery drops to 10.75 volts when in use. Stop operation, disconnect the power, and recharge the battery.
|Maximum Flow Rate Estimates|

|30 ft (10 m)||12.5 L/min|
|40 ft (12 m)||11.0 L/min|
|50 ft (15 m)||9.5 L/min|
|70 ft (21 m)||7.5 L/min|
|80 ft (24 m)||6.0 L/min|
|100 ft (30 m)||4.25 L/min|
|110 ft (33.5 m)||1.5 L/min|
