Installation
Unpacking
The valves should be unpacked immediately upon receipt from the factory and
carefully inspected for damage that may be occurred during shipping. The
equipment should also be checked against the bill of lading to make sure there are
no shortages. Any damage or shortage should be reported to the carrier.
Locating
The valves are mounted directly into the product line. Care should be taken,
however, to locate the valves in a place where they are easily reached for
maintenance and disassembly.
Installing
Line Mounted Valve: The valves may be installed in lines that are rmly supported
and capable of carrying the valve’s weight. Mount valves vertically, or as close to
vertical as possible.
