Flow Meter Installation Instructions
Step 1: Use an 8mm hex key to loosen the screw on the left side of the flow meter.
Step 2: Remove the rotor, rotate it 180 degrees, and reinstall it.
Step 3: Tighten the screw again.
-The installation position of the flow meter varies depending on the case, but the installation method is similar.
-You can design the installation position yourself. Pay attention to safe operation and prevent any possible damage to the equipment. After the water cooling system is installed, it is recommended to perform a leak test, with a test duration generally of 24 hours.

Coolant Warnings
-Oil-Based Coolant
In a water cooling system, if you use oil-based insulating coolant, it will cause the sealing ring to expand, compromising its sealing performance and increasing the risk of leakage.
-Alcohol and High-Concentration Ethylene Glycol Coolant
In a water cooling system, if you use alcohol as coolant, it will cause acrylic components to become brittle and deform, leading to acrylic cracking and increasing the risk of leakage.
-Corrosive Coolant
In a water cooling system, if you use corrosive coolant, it will corrode the sealing ring, damage the sealing ring material, compromise its sealing performance, and increase the risk of leakage.
