Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance of the dispensing system.
• Ensure proper alignment of the rigid extension with the meter housing and handle before tightening the nut.
• Do not use PTFE tape or thread sealant on the threads of the extension tube to prevent leaks.
• Allow any sealant used elsewhere to cure according to manufacturer recommendations before circulating fluid through the system.
• Regularly check and replace batteries as needed.
• Calibrate the meter periodically for accurate dispensing, especially after changes in fluid type or operating conditions.
• Inspect wetted parts for wear or damage and replace as necessary.
