16 INSTALLATION INSTRUCTIONS Grooved Pipe and Gasket Preparation
• WARNING
Always read and understand the installation instructions including the “Installation Guidelines” provided on page 15. Failure to follow these preliminary set-up steps before product installation can adversely affect subsequent system performance.
EDPM Tri-Seal gaskets are recommended for freezer applications. Reducing Couplings are not recommended for freezer applications. For dry pipe and freezer applications, use the Tri-Seal freezer gasket with a petroleum-free silicone lubricant. Standard lube is not recommended for this application as it freezes and can cause leakage.
The following pipe preparation is based on pipe grooved in accordance with Standard Cut Groove or Roll Groove Specifications. Refer to Tech Data Sheet G710 for Steel Pipe and Tech Data Sheet G720 for Copper Tubing. Refer to the individual technical data sheets (listed below) for additional information.
