Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and warranty coverage.
• Thread the extension into the housing until it bottoms out, align with meter housing and handle, then firmly tighten the nut.
• Do not use PTFE tape or thread sealant on the threads of the extension tube to prevent leaks.
• Let sealant cure according to manufacturer recommendations before circulating fluid through the system.
• Ensure proper alignment and secure all fittings before use.
• Regularly check for leaks and wear.
• Re-calibrate as needed for optimal accuracy.
• Use recommended batteries for extended life.
