HOW TO INSTALL BPV31
Position: Pick a straight section of copper tubing with at least 2" of clearance. Wipe the surface clean.
Mount: Place the two clamp halves around the tube, align the piercing needle perpendicular to the tube, and finger-tighten the clamp bolts evenly.
Tighten: Use the included hex key to snug the clamp bolts to a firm seat. The patented gasket compresses around the tube to form a leak-free seal.
Pierce: Turn the valve handle clockwise until the needle fully penetrates the tubing wall, then back off one full turn to open the port.
Connect: Thread a standard 1/4" SAE service hose onto the port. Verify no leaks with soap solution before pulling vacuum or charging.
