Notes:
1.
Center the multiple injection tube assembly in the duct height.
2.
The injection tubes should be mounted
level
within the duct or AHU.
3.
Install injection tubes with the orifices injecting upwards.
4.
All condensate drain piping is by others.
5.
Condensate must drain by gravity to an open drain. Condensate cannot be elevated.
6. Each condensate connection must have it’s own steam trap. Condensate connections
cannot be combined together to a common steam trap.
7. A common condensate drain line can be used after the individual steam traps.
