Pressurized SAM-e
Plumbing
Steam Line
Condensate Return Line
When pressurized steam (2-50 psi) enters the SAM-e, steam expansion reduces pressure down
to almost atmospheric pressure. Therefore condensate cannot be lifted after the F+T trap. A
high temperature condensate pump may be used to achieve this.
Condensate from the SAM-e must always be returned to an atmospheric condensate return
main.
Long condensate runs (more than 20 ft.) should be oversized for better flow. Refer to Figure 33
and 34.
For proper trap installation, refer to Figure 15.
