Note:
Horizontal installation
Recommended
To prevent the LLS4000 from being covered by insulation
material (e.g., in low-temperature applications), we recommend
using a concentric reducer (e.g., DN32-DN50) between the
standpipe and the LLS4000 weld nipple, as shown in the sketch.
Note:
Vertical or inclined
installation is not
recommended.
