2. Safety Information
Always observe the following safety precautions when handling pool equipment:
- Disconnect Power: Before performing any maintenance or installation on your pool cleaner, ensure the pool pump is turned off and disconnected from its power source to prevent accidental startup.
- Read Instructions: Familiarize yourself with the entire manual before beginning installation or maintenance.
- Use Correct Tools: Use only appropriate tools for the task to avoid damage to the product or injury.
- Keep Children Away: Ensure children and pets are kept away from the work area during installation and maintenance.
- Proper Disposal: Dispose of old parts responsibly according to local regulations.
3. Installation Instructions
This section provides step-by-step instructions for replacing the swivel assembly on your automatic pool cleaner. Ensure you have the replacement GW9012 swivel assembly and any necessary basic tools (e.g., pliers, screwdriver, if required by your specific cleaner model) before you begin.
3.1. Preparation
- Turn off the pool pump and disconnect the automatic pool cleaner from the pool hose.
- Remove the cleaner from the pool and place it on a clean, flat surface.
- Identify the existing swivel assembly on your cleaner. It is typically located where the hose connects to the cleaner head.
3.2. Removing the Old Swivel Assembly
- Depending on your specific cleaner model (Great White or Lil Shark), the swivel assembly may be held in place by a retaining clip, screw, or simply by friction. Carefully inspect your cleaner's head.
- If there is a retaining clip or screw, remove it using appropriate tools.
- Gently pull or twist the old swivel assembly to detach it from the cleaner head. Note how it was oriented for easier installation of the new part.
- Inspect the area for any debris or wear that might affect the new assembly. Clean if necessary.
3.3. Installing the New GW9012 Swivel Assembly
- Take the new Pentair Sta-Rite GW9012 Swivel Assembly.
- Align the new swivel assembly with the opening on the cleaner head. Ensure the orientation matches the original assembly.
- Push the new swivel assembly firmly into place until it is securely seated. If a retaining clip or screw was removed, reattach it now.
- Verify that the swivel assembly can rotate freely without excessive play or stiffness.
3.4. Post-Installation
- Reconnect the pool hose to the newly installed swivel assembly.
- Place the automatic pool cleaner back into the pool.
- Turn on the pool pump and observe the cleaner's operation. Ensure it moves freely and the hose does not tangle.

4. Operating Principles
The GW9012 Swivel Assembly is a passive component that facilitates the movement of your automatic pool cleaner. It allows the cleaner to rotate independently of the hose, preventing the hose from kinking or tangling as the cleaner traverses the pool floor and walls. A properly functioning swivel assembly ensures efficient cleaning coverage and extends the life of your pool hose by reducing stress on connections.
If the swivel assembly is worn or damaged, the cleaner may exhibit restricted movement, get stuck in corners, or fail to cover the entire pool area. Replacing a faulty swivel assembly restores the cleaner's intended operational efficiency.
5. Maintenance
Regular inspection and minor maintenance can prolong the life of your GW9012 Swivel Assembly and ensure optimal performance of your pool cleaner.
- Visual Inspection: Periodically remove the cleaner from the pool and visually inspect the swivel assembly for cracks, excessive wear, or debris accumulation.
- Check for Free Movement: Manually rotate the swivel assembly to ensure it moves freely without binding or excessive resistance. If it feels stiff or gritty, it may indicate internal wear or debris.
- Clean Debris: If debris (e.g., hair, small leaves) is caught around the swivel mechanism, carefully remove it.
- Replacement: If the swivel assembly shows significant wear, cracks, or no longer rotates freely, it should be replaced to maintain the cleaner's efficiency.
6. Troubleshooting
If your automatic pool cleaner is not performing as expected, the swivel assembly might be a contributing factor. Here are some common issues and potential solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Cleaner gets stuck or moves in circles. | Worn or seized swivel assembly. | Inspect the swivel assembly for free movement. Replace if it is stiff, damaged, or not rotating properly. |
| Hose tangles frequently. | Swivel assembly not rotating freely. | Check for debris obstructing the swivel. If clear, the internal mechanism may be worn; replace the assembly. |
| Water leaks from the swivel connection. | Damaged O-rings or seals within the swivel, or improper installation. | Ensure the swivel is correctly seated. If leaks persist, the assembly may be faulty and require replacement. |
