Hayward 925ADC Navigator Pro Suction Pool Vacuum User Manual

1. Introduction

This manual provides comprehensive instructions for the installation, operation, and maintenance of your Hayward 925ADC Navigator Pro Suction Pool Vacuum. Designed for efficient and automatic pool cleaning, this device utilizes your existing filtration system to navigate and clean your pool's surfaces. Please read this manual thoroughly before use to ensure proper function and longevity of your cleaner.

2. Safety Information

Always observe basic safety precautions when installing and operating this product. Failure to follow these instructions could result in injury or property damage.

• Ensure the pool pump is turned off before connecting, disconnecting, or performing any maintenance on the cleaner.
• Keep children and pets away from the pool area when the cleaner is in operation.
• Do not operate the cleaner if any parts are damaged or missing.
• Regularly inspect hoses and connections for wear or damage.
• This cleaner is designed for pool use only. Do not use it for other purposes.

3. Setup and Installation

The Hayward 925ADC Navigator Pro is designed for easy, tool-free installation. Follow these steps to set up your cleaner:

3.1 Unpacking and Component Check

Carefully remove all components from the packaging. Verify that all parts are present and undamaged. Refer to the product diagram (if available in your physical manual) for a complete list of components.

3.2 Connecting the Cleaner

1. Ensure your pool's filtration system is turned off.
2. Connect the Hayward 925ADC Navigator Pro Suction Pool Vacuum to the skimmer or a dedicated suction port. No tools are required for this connection.
3. Assemble the hose sections. The correct number of hose sections should allow the cleaner to reach all areas of the pool without excess slack or tension.
4. Submerge the cleaner and hose into the pool, allowing them to fill with water to remove air.
5. Turn on the existing filtration system to power the cleaner.

3.3 Adjusting Suction and Flow

Proper suction adjustment is crucial for optimal cleaner performance. The Navigator Pro operates efficiently with less suction compared to some other models, allowing for better water flow through the skimmer.

• Use the supplied flow gauge (if included) to ensure the cleaner is operating at the proper speed.
• If running the cleaner through the skimmer only, utilize the supplied pressure regulator/adjuster to fine-tune the suction.
• Adjust the suction to allow the cleaner to move freely across the pool floor and walls without getting stuck or moving too slowly.

4. Operation

Once properly installed and adjusted, the Hayward 925ADC Navigator Pro operates automatically to clean your pool.

4.1 Automatic Cleaning Cycle

• The cleaner will move around the pool floor, walls, and coves using its SmartDrive steering technology.
• The enhanced suction path is designed for efficient and faster debris pickup.
• The cleaner operates silently, without pulsating hoses or noisy parts.
• Allow the cleaner to run for a sufficient period to cover the entire pool surface.

4.2 Wall Climbing Capability

The Navigator Pro has wall climbing capability. However, pool coverage and wall climbing may be affected by specific pool shapes, surfaces, and water chemistry. The cleaner may not climb the wall under certain conditions.

5. Maintenance

Regular maintenance ensures the longevity and optimal performance of your Hayward 925ADC Navigator Pro.

5.1 Routine Checks

• Inspect Feet and Wings: Regularly check the feet and wings for wear, especially if your pool has a rough surface like pebble. Worn parts can affect cleaning efficiency and movement. Replacement is typically recommended annually or as needed.
• Hose Inspection: Check all hose sections for cracks, leaks, or blockages. Ensure connections are secure.
• Debris Removal: Periodically check the cleaner for any lodged debris, such as large leaves or twigs, which can jam the drive gear assembly. If jammed, remove the cleaner from the water and access the drive gear to clear the obstruction.
• Filter System: Ensure your pool's filter system is clean and operating efficiently, as this directly impacts the cleaner's suction power.

5.2 Rebuilding and Repairs

For advanced maintenance, such as a complete rebuild, Hayward offers replacement parts including bottom units, steering gearboxes, and spindle gear sets. If attempting a rebuild, it is recommended to consult official Hayward repair guides or videos. Take pictures during disassembly to aid in correct reassembly. A Phillips head screwdriver, some knowledge, and patience are typically required.

6. Troubleshooting

This section addresses common issues you might encounter with your Hayward 925ADC Navigator Pro.

• Cleaner Stops or Moves Slowly:
  • Check for obstructions in the cleaner's intake or drive mechanism.
  • Verify that the pool pump is running and providing adequate suction.
  • Ensure the hose length is appropriate and not causing drag or tension.
  • Adjust the pressure regulator/adjuster to increase suction if necessary.
  • Inspect feet and wings for excessive wear.
• Cleaner Gets Stuck:
  • The cleaner may occasionally get stuck on floor drain covers or other pool features. It often frees itself, but manual intervention may be needed.
  • Ensure proper hose length and buoyancy to prevent tangling or getting caught.
  • Check for large debris that might be impeding movement.
• Poor Cleaning Performance:
  • Confirm that the suction is correctly adjusted using the flow gauge.
  • Inspect the cleaner's feet and wings for wear, as this impacts its ability to agitate and pick up debris.
  • Ensure the pool filter is clean and not impeding water flow.
  • The cleaner may have difficulty with very large leaves or heavy debris; manual removal may be necessary for such items.
