5. Setup
Follow these steps to set up your SunSun CHJ-1503 ECO water pump:
- Choose Location: Place the pump in a stable, submerged position within your pond, pool, or fountain basin. Ensure it is on a flat surface and not obstructed by debris. The integrated suction cups (24) and rubber feet (25) can help secure its position.
- Assemble Fountain Components:
- Attach the desired fountain nozzle (1, 2, or 3) to the fountain base (4).
- Connect the extension tube (5) to the fountain base (4) if additional height is required.
- Secure the assembled fountain column to the pump body (19) using the threaded ring (7) and connector (8).
- Connect Hoses (if not using fountain): If using the pump for general water circulation or to feed a filter, attach appropriate hoses to Outlet 1 (11) or Outlet 2 (12) using the provided connectors and the elbow outlet (13) if needed.
- Submerge Pump: Carefully place the pump into the water, ensuring it is fully submerged before connecting to power.
- Connect to Power: Plug the pump into a properly grounded electrical outlet with GFCI/RCD protection.
6. Operation
Once installed, operating your pump is straightforward:
Image: The pump can operate in two modes: creating decorative fountain jets or functioning as a standard water pump for circulation.
- Starting the Pump: The pump will begin operating once connected to a power source.
- Adjusting Flow Rate: The pump features an integrated flow control valve (18). Rotate the regulator (9) or adjust the valve to precisely control the water flow rate according to your needs. This allows for optimization of fountain height or circulation intensity.
- Changing Fountain Effects: If using the fountain function, you can change the water spray pattern by interchanging the fountain nozzles (1, 2, 3). Experiment with different nozzles to achieve desired aesthetic effects.

7. Maintenance
Regular maintenance is crucial for the longevity and efficient operation of your pump. The pump is designed for easy, tool-free access for cleaning.
Image: Step-by-step visual guide demonstrating how to disassemble the pump for cleaning and maintenance.
- Disconnect Power: Always unplug the pump from the power source before any maintenance.
- Remove Filter Cover: Press the side clips to remove the filter cover.
- Access Main Casing: Press the clips on the main casing to open it. The filter sponge (16) can be cleaned or replaced at this stage.
- Remove Base: Remove the base by sliding it in the direction of the arrow.
- Remove Pump Body: Rotate the pump body (19) more than 90 degrees to the left to detach it.
- Clean Rotor Unit: Carefully pull out the rotor unit (21) for cleaning. The ceramic shaft (visible in image PT04) is wear-resistant but should be inspected for debris. Clean the impeller and the inside of the motor housing (23) with a soft brush and clean water.
- Reassemble: Reassemble all components in reverse order, ensuring all seals (22) are correctly seated.
