5. Operating Instructions
The Jebao SOW-20 controller allows for various modes and adjustments to customize water flow in your aquarium.

Controller Functions:
- MODE Button: Press to cycle through the 8 different flow modes. Each mode simulates a unique wave pattern or constant flow.
- SPEED/FEED Button:
- Speed: In normal operation, press to adjust the pump's speed within the selected mode.
- Feed Mode: Press and hold for 3 seconds to activate a 10-minute pause, allowing fish to feed without strong currents. The pump will automatically resume after 10 minutes.
- Wi-Le/LOCK Button:
- Wireless (Wi-Le): Used for synchronizing multiple SOW-20 pumps (Master/Slave setup). Refer to the 'Master/Slave Synchronization' section below.
- Lock: Press and hold to lock the current settings, preventing accidental changes. Press and hold again to unlock.
- POWER/PUMP Dial: Rotate this dial to finely adjust the overall power and flow rate of the pump, from 1,700 L/H to 20,000 L/H.
Night Sensor:
The controller features a built-in light sensor. When the aquarium lights dim or turn off, the pump will automatically reduce its power output to simulate natural nighttime conditions, providing a calmer environment for your aquatic inhabitants and conserving energy.

Master/Slave Synchronization:
If you have two Jebao SOW-20 pumps, you can synchronize them wirelessly for coordinated flow patterns:
- Designate one pump as the 'Master' and the other as the 'Slave'.
- On the Master controller, press and hold the 'Wi-Le' button until the 'Master' indicator light illuminates.
- On the Slave controller, press and hold the 'Wi-Le' button until the 'Slave' indicator light illuminates.
- The two pumps will now operate in sync, either synchronously or asynchronously, depending on the selected mode.

6. Maintenance
Regular maintenance ensures the longevity and optimal performance of your Jebao SOW-20 pump.
- Cleaning Frequency: It is recommended to clean the pump every 1-2 months, or more frequently if you notice reduced flow or increased noise.
- Disassembly: Disconnect the pump from the power supply. Carefully remove the pump from the aquarium. Twist and pull apart the pump housing to access the impeller.
- Impeller Cleaning: Remove the impeller and clean it thoroughly with a soft brush under running water. Remove any algae, debris, or calcium buildup. The pump features a durable ceramic shaft, which is resistant to corrosion.
- Housing Cleaning: Clean the pump housing and protective cage, ensuring all water passages are clear.
- Reassembly: Reassemble the pump in reverse order, ensuring all parts are securely fitted.
- Testing: Place the pump back into the aquarium, ensuring it is fully submerged, and reconnect the power.
