INSTALLATION INSTRUCTIONS 15 Installation Guidelines
These installation instructions do not take the place of nor eliminate the need for the installer to fully read and understand the complete Grinnell Mechanical Products Installation Handbook and individual product technical data sheets for the latest instructions, techniques, and care and maintenance information. This document does not supersede or replace the individual product technical data sheets. Current docu- mentation can be obtained by contacting Grinnell Mechanical Products or by visiting www.grinnell.com.
• WARNING
Failure to follow these instructions may result in improper product instal- lation, joint failure or leakage, serious personal injury, and/or property damage.
The following instructions should be used as a guideline for the proper installation of GRINNELL grooved products.
1. Alwaysreadandunderstandtheinstructions.
2. To avoid serious personal injury, wear safety glasses, hard hat and
foot protection.
3. Never remove any piping component without verifying that the sys- tem is de-pressurized and drained. Failure to do so may result in se- rious personal injury.
4. Ensure that the supplied gasket is suitable for the intended appli- cation. To prevent deterioration of the gasket material, a petroleum lubricant should never be used. Use a recommended lubricant to in- stall the gasket.
5. The pipe and tubing groove dimensions must be in accordance with Standard Cut Groove or Roll Groove Specifications. Refer to the Prep Equipment section of this manual or tech data sheets G710 and G720 for more information.
6. Ensure that the coupling keys are engaged in the grooves.
7. Always tighten nuts evenly by alternating sides. Uneven tightening can cause the gasket to pinch or bind. If a gasket becomes pinched, replace it immediately. Not applicable to the installation-ready Fig- ure 740 and Figure 640 Pivot-Bolt Rigid Couplings.
8. Torque values are supplied per manufacturer's instructions for pow- er impact wrench. Always refer to the manufacturer’s instructions for settings.
9. Exceeding the suggested torque values may cause damage to the coupling and/or result in pipe-joint failure. Minimum bolt torque is required for the coupling to meet the published performance parameters.
10. Always inspect each joint to ensure that the coupling is properly installed.
