Installation & Key Precautions

First, prepare all necessary tools and parts. Securely fix the cylinder to its housing. Insert the piston into the push rod. Adjust the cylinder by turning it to set the activation temperature. Finally, insert the stop pin into the hole on the arm to finish installation.
Ensure the cylinder is firmly fixed to avoid operation issues. Adjust temperature settings gradually. Regularly lubricate moving parts for smooth function. Install in a well-ventilated area away from direct rain. In winter, remove and store the cylinder to prevent damage from freezing.
