The POOLHACKER 3-in-1 Winter Closing Kit is designed to simplify the pool winterization process, ensuring your pool remains clear and protected throughout the off-season.

2. Setup and Preparation
Proper preparation is key to effective winterization. Follow these steps before applying the winterizing capsules:
- Clear Pool Debris: Before adding any chemicals, ensure your pool is free of debris, algae, floating leaves, and any other impurities. Use a skimmer net and pool vacuum as needed.
- Perform Super Chlorination/Shock Treatment: Add the winterizing capsules 24 hours after performing a super chlorination or pool shock treatment. This ensures the water is properly sanitized before winterization.
- Adjust Water Level (if using a pool pillow): If you plan to use a pool pillow, ensure the water level is at least 12 inches below the skimmer opening to allow for ice expansion.

Important Safety Information:
Keep out of reach of children.
3. Operating Instructions
Once your pool is prepared, follow these simple steps to apply the POOLHACKER Winter Closing Kit:
- Open the Capsules: The kit contains two winter balls (capsules). Locate the plug on each capsule. Open the plug and place the capsules into the pool with the mouth facing downward.
- Place Capsules in Pool: Simply place both "Winter Boost" and "Winter Pure" capsules together anywhere in the pool. They are designed to float and dissolve over time, releasing their contents to treat the water.
- Cover the Pool: After placing the capsules, cover your pool to prevent debris from falling into it and to protect it from harsh winter elements.

4. Maintenance and Storage
The POOLHACKER Winter Closing Kit is designed for a single application per winter season for pools up to 30,000 gallons. Once applied, the capsules will dissolve and work throughout the winter to maintain water clarity and protect pool surfaces.
- During Winter: Regularly check your pool cover for accumulated debris (leaves, snow, etc.) and remove it to prevent damage to the cover or pool structure.
- Spring Opening: When it's time to open your pool in the spring, you should find the water clear and ready for minimal cleanup, thanks to the kit's preventative action.
- Storage: Store any unused kits or components in a cool, dry place, away from direct sunlight and out of reach of children and pets.

5. Troubleshooting
While the POOLHACKER Winter Closing Kit is designed for ease of use and effectiveness, here are some common issues and general advice:
- Water Not Clear in Spring:
- Ensure proper pre-winterization steps were followed, including thorough cleaning and shock treatment.
- Verify the pool size is within the 30,000-gallon capacity for a single kit. Larger pools may require additional kits.
- Check for any damage to the pool cover that might have allowed excessive debris or sunlight into the pool.
- Capsules Not Dissolving:
- Ensure the plugs were fully removed from the capsules before placing them in the water.
- Water temperature can affect dissolution rate; colder temperatures may slow the process, but they will continue to work.
