Setup Instructions
- Choose Application Type: Determine if the pump will be used in a wet (submerged) or dry (external) application.
- Attach Hose Connector: Select the appropriate hose connector (1/2-inch, 5/8-inch, or 3/4-inch) for your tubing and securely attach it to the pump's outlet.
- Connect Tubing: Connect your desired tubing to the attached hose connector. Ensure a tight fit to prevent leaks.
- Position the Pump:
- For Wet Applications: Place the pump completely submerged in water, ensuring the water level is above the pump's intake.
- For Dry Applications: Position the pump externally, ensuring it is below the water level of the source to allow for gravity-fed intake.
- Secure the Pump: Use the four suction cups on the base of the pump to secure it firmly to a clean, smooth surface. This helps reduce vibration and noise.
- Manage Power Cord: Route the power cord safely, using the included cord management suction cups to keep it tidy and prevent accidental dislodgement. Ensure a drip loop is formed to prevent water from traveling along the cord to the electrical outlet.


Operating Instructions
- Ensure Water Level: For submerged applications, confirm the pump is fully immersed in water. For dry applications, ensure the pump is primed (water flows into the intake by gravity or manual priming) before starting.
- Plug In: Connect the pump's power plug to a properly grounded electrical outlet. The pump will begin operating.
- Adjust Flow Rate: Use the adjustable flow valve located on the pump to increase or decrease the water flow to your desired level.
- Monitor Performance: Observe the pump's operation to ensure proper water circulation and flow.
Maintenance
Regular maintenance is crucial for the longevity and efficient operation of your Imagitarium IN-CIRC 800 Water Pump.
- Disconnect Power: Always unplug the pump from the power source before performing any cleaning or maintenance.
- Disassemble: Carefully remove the pump from its location. Depending on the model, you may need to unclip the intake cover to access the impeller.
- Clean Impeller and Housing: Remove any debris, algae, or mineral buildup from the impeller, impeller shaft, and pump housing. A small brush or cotton swab can be helpful for hard-to-reach areas.
- Rinse Components: Rinse all cleaned components thoroughly with clean water.
- Reassemble: Carefully reassemble the pump, ensuring all parts are correctly seated.
- Check Tubing: Periodically inspect the connected tubing for blockages or kinks that could impede water flow.
