Setup and Installation

Proper installation is crucial for the optimal performance of your skimmer. This unit is designed for wall-mounted installation in above-ground pools. Ensure you have all components listed in the Product Overview before beginning.

Installation Steps:

1. Prepare the Pool Wall: If replacing an existing skimmer, carefully remove the old unit. If installing new, use the provided opening template to accurately mark and cut the skimmer opening in your pool wall. Ensure the area is clean and free of debris.
2. Install Skimmer Housing: Position the skimmer housing through the prepared opening from the outside of the pool.
3. Apply Gaskets: Place the appropriate gaskets on both sides of the pool wall around the skimmer opening. These create a watertight seal.
4. Attach Face Plate: From the inside of the pool, align the face plate with the skimmer opening and secure it to the skimmer housing using the provided face plate screws. Tighten screws evenly to ensure a proper seal, but do not overtighten.
5. Install Flap Weir and Debris Basket: Insert the flap weir into its designated slot within the skimmer opening. Place the debris basket inside the skimmer housing.
6. Connect Hoses: Attach the necessary hose adapters to the skimmer and connect your pool's filtration hoses. Use Teflon tape on threaded connections to prevent leaks.
7. Install Return Assembly: Locate the return fitting opening on your pool wall. Install the complete return assembly, including the eye-ball fitting, gaskets, and other fittings, ensuring a secure and watertight connection.
8. Final Checks: Once all components are installed, fill the pool to the appropriate level and check for any leaks around the skimmer and return fittings. Tighten connections as needed.

Detailed, easy-to-follow instructions with an opening template are included with the product to assist with the installation process.

Operating Instructions

The Hydrotools Model 8940 skimmer operates by drawing water from the pool surface, where most floating debris accumulates, into the filtration system. This process helps maintain water clarity and reduces the workload on your main pool filter.

Basic Operation:

• Ensure your pool pump is running to create the necessary suction for the skimmer to operate.
• The flap weir at the skimmer opening will automatically open inward when the pump is on, allowing water and debris to enter. When the pump is off, it helps prevent debris from floating back into the pool.
• Debris such as leaves, insects, and other floating particles will be collected in the debris basket located inside the skimmer housing.
• The included vacuum plate can be used to connect a manual pool vacuum hose to the skimmer, allowing you to vacuum the pool floor directly through the skimmer's suction.

Maintenance

Regular maintenance of your skimmer is essential for its efficiency and longevity. The skimmer is made from Acrylonitrile Butadiene Styrene (ABS) material, which is durable but requires proper care.

Maintenance Schedule:

• Empty Debris Basket: Check and empty the skimmer debris basket daily or as needed, especially after heavy winds or rain. A full basket restricts water flow and reduces skimming efficiency. To empty, turn off the pool pump, remove the top cover, lift out the basket, dispose of debris, and replace the basket and cover.
• Clean Skimmer Interior: Periodically clean the inside of the skimmer housing to remove any accumulated grime or algae. Use a soft brush and a pool-safe cleaner suitable for ABS plastics.
• Inspect Flap Weir: Ensure the flap weir moves freely and is not obstructed by debris. A stuck weir can impair skimming action.
• Check Gaskets and Connections: Annually, or if you notice leaks, inspect all gaskets and connections for wear, cracks, or looseness. Replace worn gaskets and tighten loose fittings as necessary.
• Winterization: If you live in an area with freezing temperatures, follow proper pool winterization procedures, which typically include draining the skimmer and return lines to prevent freeze damage.
