Usage Method
Tube Installation
• Open the pump head shell and use a tube pressure lever to secure the tube at the illustrated position.
• Turn the tube lever counterclockwise and insert the tube between the roller and the pump shell.
• After fastening the other pump shell, use a tube lever to rotate the main shaft following the instructions in the diagram, and adjust the tube
position inside the shell.
