2. Setup and Initial Use
- Unpacking: Remove the cooler from its packaging. Inspect for any damage during transit.
- Initial Cleaning: Before first use, wipe the interior and exterior surfaces with a damp cloth and mild detergent. Rinse thoroughly with water and ensure the cooler is completely dry before storage or use. This prevents any manufacturing residues from affecting your food or beverages.
- Pre-chilling (Optional but Recommended): For optimal ice retention, pre-chill the cooler by filling it with a small amount of ice or ice packs several hours before loading your main contents. This lowers the internal temperature of the cooler itself.
- Loading Contents:
- Place items that need to stay coldest at the bottom.
- Fill any empty spaces with ice to maximize cold retention. Block ice generally lasts longer than cubed ice.
- Ensure the lid is securely latched using the dual snap-fit latches.
3. Operating Instructions
3.1 Using the Quick-Access Hatch
The quick-access hatch located on the main lid allows you to retrieve items without fully opening the cooler. This feature helps to minimize the escape of cold air, thereby extending ice retention.
- To open: Simply lift the small hatch cover on the top of the lid.
- To close: Press the hatch cover firmly until it snaps securely into place.

3.2 Draining the Cooler
The threaded drain plug allows for easy removal of melted ice water without tilting the cooler. This is particularly useful for large, heavy coolers.
- To drain: Unscrew the drain plug located at the bottom side of the cooler.
- For continuous draining: A standard garden hose can be attached to the threaded drain plug for convenient water removal.
- To close: Screw the drain plug back in tightly to prevent leaks.

3.3 Transporting the Cooler
The reinforced swing-up handles are designed for comfortable and secure lifting. The integrated tie-down loops allow you to secure the cooler during transport, preventing movement.
- Always lift the cooler using both handles, especially when full, due to its significant weight.
- Utilize the tie-down loops with ropes or straps to secure the cooler in vehicles or on boats.
4. Maintenance and Care
Proper maintenance will extend the life and performance of your Igloo cooler.
- Cleaning: Wipe interior and exterior surfaces clean before storing and between uses.
- Odor and Stain Prevention: To prevent stains and odors, empty the cooler of contents immediately after use.
- Light Cleaning: Light dirt or stains can be cleaned with water or a mild detergent.
- Tougher Stains: Tougher stains may be cleaned with a diluted solution of baking soda and water.
- Rinsing and Drying: Ensure all cleaning agents are thoroughly rinsed and the cooler is completely dry before storage to prevent mold or mildew.
- Storage: Store the cooler with the lid slightly ajar to allow for air circulation and prevent odors.
5. Troubleshooting
- Poor Ice Retention:
- Ensure the lid is securely latched and the quick-access hatch is fully closed.
- Check the drain plug for a tight seal.
- Pre-chill the cooler before use, especially in warm environments.
- Fill the cooler as much as possible with ice and contents; a full cooler retains cold better than a partially filled one.
- Keep the cooler in the shade and out of direct sunlight when possible.
- Lid Not Sealing Properly:
- Inspect the lid and cooler rim for any debris or damage that might prevent a proper seal.
- Ensure the dual snap-fit latches are fully engaged.
- Difficulty Draining:
- Ensure the drain plug is fully unscrewed.
- Check for any blockages in the drain opening.
