4.4 Pipe hanging installation

CAUTION: Lifting lugs
Use unit lifting lugs only to lift unit as shipped from factory. Unit must be empty and
disconnected from pipe, and other restraints. Use proper rigging procedures. Failure to
follow these instructions could result in injury or property damage.
The wet filled weight of the Series CRS separators can exceed the strength of the supports
used.
Make sure that provisions are made to properly support the wet filled separator.
Welding to the pressure vessel boundary will void the ASME stamp.
NOTICE:
Never use the separator itself as a form of piping support. Please support separator and
piping according to the local building code. Failure to follow these instructions may result in
property damage.
A manual blowdown valve can be added to the blowdown connection at the bottom of the
separator. The function of the blowdown valve is to facilitate the purging of sediment from
the vessel.
