Setup
Unpacking and Initial Inspection
Carefully remove the cooler from its packaging. Inspect for any signs of damage during transit. Ensure all components, including the drain plug and latches, are intact and functional.
Initial Cleaning
Before first use, clean the interior and exterior of the cooler with mild soap and water. Rinse thoroughly and allow to air dry completely to prevent odors.
Pre-Chilling for Optimal Performance
For best ice retention, pre-chill your cooler before loading. Place a bag of ice or frozen water bottles inside the cooler with the lid closed for several hours or overnight. This lowers the internal temperature, reducing ice melt when you add your contents.

Freeze or pre-chill all food before placing in cooler. Arrange ice packs to surround food and drink. Crushed ice can be used as a bottom layer.
Operating Instructions
Lid Operation
The cooler features two rubber latches for secure closure. To open, pull the blue tab of each latch upwards and away from the cooler body. To close, align the lid and push the latches down until they securely engage the cooler body.
Carrying and Transport
The cooler is equipped with durable rope handles for easy transport. For heavy loads, it is recommended that two people carry the cooler using these handles. The cooler's robust construction allows it to be moved even when full.

Drain Spout Usage
The cooler includes an easy-to-drain spout with garden hose compatibility. To drain melted ice or water, unscrew the cap from the drain spout located on the side of the cooler. For continuous draining, attach a standard garden hose to the spout. Ensure the cap is securely tightened after draining to maintain the cooler's seal.

Maintenance
Cleaning
Clean the cooler with mild soap and water as needed. For stubborn stains or odors, a solution of baking soda and water can be used. Avoid abrasive cleaners or harsh chemicals that could damage the cooler's surface or insulation.
Storage
Store the cooler in a cool, dry place with the lid slightly ajar to allow for air circulation and prevent mildew or odors from forming. Ensure the drain plug is open during storage to allow any residual moisture to escape.
Troubleshooting
Reduced Ice Retention
- Issue: Ice melts faster than expected.
- Solution: Ensure the cooler was pre-chilled before use. Minimize opening the lid. Ensure latches are fully secured and the lid gasket is clean and free of debris. Consider using a higher ice-to-content ratio.
Lid Not Sealing Properly
- Issue: Lid does not close tightly or latches are difficult to engage.
- Solution: Check the rubber gasket around the lid for any damage, tears, or debris. Clean the gasket and the rim of the cooler. Ensure the latches are properly aligned and not obstructed.
Drain Spout Leakage
- Issue: Water leaks from the drain spout.
- Solution: Ensure the drain cap is securely tightened. Check the drain plug's rubber washer for wear or damage and replace if necessary.
