Follow these steps to properly set up your Jebao DCQ pump:

**Unpacking**: Carefully remove all components from the packaging. Inspect for any damage.
**Placement**: The pump is designed for submersible use in a sump or directly in the aquarium. Ensure it is placed on a stable, flat surface. The pump features suction cups on its base for secure placement (see Figure 7).
**Fittings**: Attach the appropriate output nozzle and intake screen to the pump. Ensure a tight fit to prevent leaks.
**Hose Connection**: Connect your return hose to the pump's output nozzle. Secure with a hose clamp if necessary (not included).
**Electrical Connection**:
- Connect the pump's power cable to the DCQ pump driver (controller).
- Connect the power adapter to the DCQ pump driver.
- Plug the power adapter into a suitable electrical outlet (110-240V, depending on your pump model).
Refer to the wiring diagram below for correct connections.

Figure 7: Wiring diagram showing connections between the pump, controller, and power adapter.
