• WARNING
Always read and understand the instructions including the “Installation Guidelines” provided on page 15. Failure to follow these instructions may result in improper product installation, joint failure, leakage, serious personal injury, and/or property damage.
This section covers the following products, listed below with their cor- responding tech data sheets.
• Figure 71 Flange Adapter (TDS G150)
Step 1. Follow the preliminary set-up steps of the Grooved Pipe and Gasket Preparation section on pages 16 and 17. Failure to follow these preliminary set-up steps before product installation can adversely affect subsequent system performance.
Step 2. Place the first segment of the assembly into the groove on the pipe.
Step 3. Bring the second half of the flange assembly together into the groove of the pipe. Insert the two coupling bolts into the bolt pads and tighten the nuts, drawing the pads together but allowing the housings to remain loose enough to permit the flange adapter to be rotated for bolt hole alignment in Step 6. Verify that the housing keys are fully engaged into the groove.
Step 4. Verify that the gasket selection is correct for the application intended. The sealing edges and outer surfaces of the gasket should be covered with a fine layer of lubricant. To prevent deterioration of the gasket material, only a petroleum-free lubricant should be used on Grade “E” “EPDM”. For assembly below 40°F (4°C) a petroleum-free silicone lubricant must be used to prevent freezing of the lubricant.
Refer to Technical Data Sheet G610 for addi- tional gasket information.
