Automatic Power Off Protection

When the pump detects no water, default phase, or over voltage, it will power off automatically. The motor will also power off if the rotor is blocked. Once the pump detects no water, it will shut off automatically for 2 minutes. If you want to restart the pump immediately, pull the plug out and plug into power again, the pump will restart again.

It comes with 2 kinds of removable water intake screens: one for normal water level, and the other is U-shape for low water level. The lowest water level is 0.8 inch.

Use As Internal or Submersible Water Pump

Hygger DC water pump can be ran externally or internally. When using the pump externally, make sure there are full of water in the pump body and the pipes before plugging in power. And place the pump at lower position than the water level.

When using the pump internally, please keep the pump fully submersible in water before plugging in power. Please use one of the 2 removable shells to prevent pump blocking.

The pond pump comes with screw nuts, o rings, and pipe connection fittings, please tighten all nuts and connections to make sure no water leaks out. You can even use extra glue to reinforce the connection.

2 Working Modes

You can set the water pump to work in normal working mode where flow rate is adjustable, or in feed mode where the pump turns off 10 minutes for feeding.

Normal Working Mode
In this mode, variable frequency powered DC controller can offer up to 71 different speed settings for steady flow mode. It's convenient and easy to control the pump. You can control the flow rate from 30% to 100% with the external controller.

"FXXX" is showing the working flow rate. When you press ▼/▲ button, the LED display will read from F030 to F100. If you press ▼/▲ button for several seconds, the working flow rate will change between F030 and F100 continuously.

Feed Mode
When the pump is working, you can press the “II” Pause button to stop it from flowing. After that, the LED indicator light shows "FEED", and the pump restarts automatically 10 minutes later. If you want to restart the pump before the default 10 minutes passed, you can press the “II” Pause button again.

Fault Codes and Troubleshooting

Fault Code Explanation Solution
Er01 Abnormal working current Check whether the pump is short of voltage, or the controller is broken.
Er02 Controller overheating Check whether the controller exposed to the sunshine or in high temperature environment.
Er03 Pump idling Check whether the pump works dry or not.
Er04 The impeller stops running Check whether the impeller is blocked or wrong power connection.
Er05 Abnormal working voltage Check the input supplying voltage.

 Warm Tips for Using This DC Water Pump

1. The external controller must be placed indoors since it's not waterproof.

2. The controller has memory function for the flow rate, if the power goes out the controller will go back to the last setting.

3. If you find the pump is failed to pump water at the beginning, please try to unplug and re-plug the power to get rid of the air inside the pump. Repeat the operation for several times until the pump works normally.

4. If you find the "Up", "Down", or "Pause" button on the controller failed to work, you may have locked the controller accidentally. Try to long press the "Pause" button for 3 seconds to unlock the controller.

5. If you need to lock the controller, please long press the "Pause" button for 3 seconds again.

Usre Manual
Question:Has anyone run this pump directly off a 24V PV panel? obviosly only want it to circulate during the day?
Answer:  To clarify, 24V does indeed turn the impeller. But it's 110/120vac into the controller and some kind of PWM/sine wave 24V out to the pump, which is a brushless DC. You could not run this from 24V solar panel directly, as it isn't just straight DC, it requires commutation from a motor controller.

Question:Can I use a lower flow rate to reduce the power consumption so I get to use fewer watts than the pump is rated for?
Answer:  Yes, the controller diplay lets you know how may watts or amps are being used for each setting.
