Important Safety Information
Always follow basic safety precautions to reduce the risk of fire, electric shock, and injury to persons, including the following:
- Read all instructions before using the appliance.
- DANGER – To avoid possible electric shock, special care should be taken when handling water near the appliance. For each of the following situations, do not attempt to repair yourself; return the appliance to an authorized service facility for service or discard the appliance.
- If the appliance falls into water, DO NOT reach for it. Unplug it first and then retrieve it. If electrical components get wet, unplug the appliance immediately.
- If the appliance shows any sign of abnormal water leakage, immediately disconnect it from the power source.
- Carefully examine the appliance after installation. It should not be plugged in if there is water on parts not intended to be wet.
- Do not operate any appliance if it has a damaged cord or plug, or if it is malfunctioning or has been dropped or damaged in any manner.
- To avoid the possibility of the appliance plug or receptacle getting wet, position the aquarium stand and tank to one side of a wall-mounted receptacle to prevent water from dripping onto the receptacle or plug. A “drip loop” should be arranged by the user for each cord connecting an aquarium appliance to a receptacle. The “drip loop” is the part of the cord below the level of the receptacle, or the connector if an extension cord is used, to prevent water from traveling along the cord and coming into contact with the receptacle. If the plug or receptacle does get wet, DO NOT unplug the cord. Disconnect the fuse or circuit breaker that supplies power to the appliance. Then unplug and examine for the presence of water in the receptacle.
- Close supervision is necessary when any appliance is used by or near children.
- To avoid injury, do not contact moving parts or hot parts such as heaters, reflector, lamp bulbs, or UV lamps.
- Always unplug an appliance from an outlet when not in use, before putting on or taking off parts, and before cleaning. Never yank cord to pull plug from outlet. Grasp the plug and pull to disconnect.
- Do not use the appliance for anything other than its intended use. The use of attachments not recommended or sold by the appliance manufacturer may cause an unsafe condition.
- Do not install or store the appliance where it will be exposed to the weather or to temperatures below freezing.
- Ensure the appliance is securely installed before operating it.
- Read and observe all important notices on the appliance.
- If an extension cord is necessary, a cord with a proper rating should be used. A cord rated for less amperes or watts than the appliance rating may overheat. Care should be taken to arrange the cord so that it will not be tripped over or pulled.
- This appliance has a polarized plug (one blade is wider than the other). As a safety feature, this plug will fit in a polarized outlet only one way. If the plug does not fit fully in the outlet, reverse the plug. If it still does not fit, contact a qualified electrician. Never use with an extension cord unless plug can be fully inserted. Do not attempt to defeat this safety feature.

Setup Guide
Follow these steps to properly set up your VEVOR Aquarium Filter:
- Prepare Filter Media: Open the filter unit and arrange the filter media in the designated trays. The 5-stage filtration typically includes: white sponge (coarse impurities), loose bio balls + black sponge (nitrifying bacteria), and loose ceramic rings + black sponge (beneficial bacteria cultivation). Ensure all media are rinsed thoroughly before placement.
- Connect Hoses: Attach the inlet and outlet hoses to the corresponding ports on the filter head. Ensure a secure connection to prevent leaks. The quick-connect design allows for easy attachment and detachment.
- Install Inlet/Outlet Components: Assemble the inlet and outlet pipe components according to your aquarium setup. The inlet typically includes a surface skimmer for oil film removal. Position the inlet near the bottom of the tank and the outlet (rain shower pipe) near the top for optimal water circulation.
- Position the Filter: Place the filter unit below the aquarium water level, ideally in a cabinet or on a sturdy surface. Ensure the hoses are not kinked and have a proper "drip loop" to prevent water from reaching electrical outlets.
- Prime the Filter: Before plugging in, ensure the filter is filled with water. Use the lift-and-release air vent valve (pump 2-4 times) to remove air from the system and draw water into the canister. Continue until water flows smoothly through the outlet.
- Connect to Power: Once the filter is primed and all connections are secure, plug the power cord into a grounded electrical outlet.

Operating Instructions
Once the filter is set up and powered on, it will begin filtering your aquarium water. Here are key operational features:
- UV Lamp Timer: The built-in UV lamp features a timer for automatic on/off settings. You can set it to operate for 4, 8, or 24-hour intervals. This helps inhibit germ growth and remove algae.
- Flow Adjustment Valve: Use the flow adjustment knob on the filter head to regulate the water flow rate. You can adjust it from maximum to minimum, or even shut it off completely for maintenance without disconnecting hoses.
- Silent Operation: The filter is equipped with a pure copper brushless motor, ensuring quiet operation (less than 50 decibels).

Maintenance
Regular maintenance is crucial for the optimal performance and longevity of your filter. The dual quick-release head design simplifies cleaning.
- Disconnect Power: Always unplug the filter from the power outlet before performing any maintenance.
- Detach Hoses: Use the quick-release levers on the inlet/outlet components to easily detach the hoses from the filter head. This allows you to move the canister for cleaning without draining the hoses.
- Open Filter Head: Release the clamps on the sides of the canister to remove the filter head.
- Clean Filter Media: Remove the filter trays and rinse the mechanical filter media (sponges, cotton filter) with old aquarium water to preserve beneficial bacteria. Replace chemical media (e.g., activated carbon, if used) as recommended by the manufacturer. Biological media (bio balls, ceramic rings) should only be gently rinsed if heavily clogged, again using old aquarium water.
- Clean Impeller: Inspect and clean the impeller and its housing. Remove any debris or buildup that could impede its rotation.
- Reassemble: Reassemble the filter in reverse order, ensuring all seals and O-rings are properly seated and free of debris to prevent leaks. The thickened and tightened silicone ring design reinforces leak prevention.
- Prime and Restart: Follow the priming steps from the Setup Guide before plugging the filter back in.

Troubleshooting
If you encounter issues with your VEVOR Aquarium Filter, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Reduced Flow Rate | Clogged filter media, air in the system, dirty impeller, kinked hoses. | Clean or replace filter media. Re-prime the filter to remove air. Clean the impeller. Check hoses for kinks. |
| Filter Not Starting / No Power | Power outage, loose plug, damaged cord, motor failure. | Check power supply and plug connection. Inspect cord for damage. If issues persist, contact support. |
| Loud Noise / Vibration | Air trapped in the filter, dirty or damaged impeller, improper seating of filter head. | Re-prime the filter to remove air. Clean or inspect the impeller for damage. Ensure the filter head is securely clamped and sealed. |
| Water Leakage | Improperly seated O-ring/gasket, loose hose connections, cracked housing. | Check and reseat all O-rings and gaskets. Tighten hose connections. Inspect the unit for visible damage. |
| Cloudy Water After Setup | Insufficient filtration time, new tank syndrome, improper filter media setup. | Allow more time for filtration. Ensure filter media is correctly layered and clean. Perform partial water changes. |
