2. Setup
- Unpacking: Remove the cooler and all accessories from its packaging. Inspect for any damage.
- Initial Cleaning: Before first use, wipe the interior and exterior with a damp cloth and mild soap. Rinse thoroughly and allow to air dry completely.
- Strap Attachment: Attach the adjustable ergonomic shoulder strap to the designated D-rings on the cooler for comfortable carrying.
- Pre-cooling (Optional but Recommended): For optimal performance, pre-cool the interior of the cooler by placing a bag of ice or ice packs inside for a few hours before loading your items.
3. Operation
Loading the Cooler:
- For best results, use a combination of ice and pre-chilled items.
- Fill the cooler with ice or ice packs, ensuring good contact with all items.
- Close the waterproof zipper completely to maintain cold retention.
Using the Vacuum Valve:
The vacuum valve is located on the side of the cooler. To enhance insulation, open the valve and gently press on the cooler to expel excess air from the insulation layer. Close the valve securely once air is removed. This creates a tighter seal, improving cold retention.
Carrying Options:
The HD20 cooler offers multiple ways to carry for convenience:
- Tote Handles: Use the top handles for quick and easy lifting.
- Adjustable Ergonomic Shoulder Strap: Attach the padded shoulder strap for hands-free transport.
- Side Grab Handles: Utilize the side handles for two-person carrying or securing the cooler.

4. Maintenance
Product Care Instructions:
- Hand Wash Only: Clean the cooler by hand using mild soap and water.
- Avoid Direct Sunlight: Prolonged exposure to direct sunlight can affect the material and insulation.
- Keep Clean and Dry: After each use, ensure the interior is thoroughly cleaned and dried to prevent mold or odors.
- Do Not Expose to Extreme Temperatures: Avoid storing the cooler in excessively hot or cold environments.
- Zipper Lubrication: Periodically apply the included zipper lubricant to the waterproof zipper to ensure smooth operation and maintain its seal.
5. Troubleshooting
Reduced Ice Retention:
- Issue: Ice melts faster than expected.
- Solution: Ensure the cooler is pre-cooled before use. Verify the zipper is fully closed and sealed. Use the vacuum valve to remove excess air from the insulation layer. Minimize opening the cooler frequently.
Stiff Zipper:
- Issue: The waterproof zipper is difficult to open or close.
- Solution: Apply the provided zipper lubricant along the entire length of the zipper teeth. Work the zipper back and forth several times to distribute the lubricant evenly. Regular lubrication is recommended.
Leakage:
- Issue: Water is escaping from the cooler.
- Solution: Check that the main zipper is completely closed and sealed. Ensure the vacuum valve is securely tightened. Inspect the cooler for any visible damage or punctures. If damage is found, contact customer support.
