Questions answered in Grinnell manuals
What safety precautions should be taken during installation?
Always wear safety glasses, hard hat, and foot protection. Never remove piping components without verifying the system is depressurized and drained. Failure to do so may result in serious personal injury.
What type of lubricant should be used on EPDM gaskets?
A petroleum-free silicone lubricant must be used to prevent freezing of the lubricant when assembling below 40°F (4°C). Petroleum lubricants should never be used on Grade “E” “EPDM” gaskets.
