Installation Tips

• Use compatible 6–8mm flexible tubing and secure with clamps or compression fittings for leak-free connections.
• Ensure flat contact surface between the heat source and block; consider a thin layer of thermal paste to improve conductivity.
• Flush the cooling loop before first use to remove debris, and use corrosion inhibitors if mixing metals in the loop.

Maintenance and Care

• Inspect fittings and tubing periodically for wear or leaks.
• Drain and clean the block if performance drops; avoid harsh abrasives on the aluminum finish.
• Replace coolant periodically following the coolant manufacturers recommendations.
