32 INSTALLATION INSTRUCTIONS Flange Adapters
Figure 61 and Figure 71 Flange Adapters (2 to 12 Inch)
• 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 61 Flange Adapter (TDS G515)
• 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. Insert one flange bolt (not supplied) in the hinge section of Flange Adapter. Place the hinged assembly into the groove on the pipe.
Step 3. Close the flange with another bolt. To ease in the closure of the Flange Adapter, two tabs are provided. Take an adjustable wrench and place it over the two tabs as shown. Move the wrench parallel to the pipe until the holes align. Once the holes align, insert a bolt. Verify that the housing keys are fully engaged into the groove.
Step 4. The sealing edges and outer surfaces of the gasket should be covered with a fine layer of lubricant. To prevent gasket deterioration, a petroleum-free lubricant is recommended for all EPDM gaskets. For applications below 40°F (4°C), a petroleum-free, silicone-based lubricant such as Dow Corning* No. 7 Release Compound must be used to prevent freezing of the lubricant.
For NSF Requirement:
In order to retain the NSF 61 certification, an NSF 61 certified lubricant must be used for the intended service.
To prevent deterioration of the gasket material, a petroleum lubricant should not be used on Grade “E” or “EN” “EPDM” gaskets.
Dow Corning* No. 7 Release Compound is available through Grinnell Mechanical Products.
