Notes:
1.) Center the Fast-Pac injection tube assembly in the duct height.
2.) The injection tubes should pitch back towards the header with a minimum
of 2" per foot of pitch (see above illustration).
3.) Install injection tubes with the orifices injecting upwards.
4.) All condensate drain piping is by others.
