3. SAM-e SHORT ABSORPTION MANIFOLD
(1) Absorption distance is the minimum distance an obstruction can be placed
downstream of the SAM-e to prevent condensing on the obstruction.
(2) If any of the ducts of the AHU conditions are changed, the absorption distance may
change due to a increase or decrease in the ducts temperature, amount of fresh air,
various outside conditions, setpoint requirements, etc. If this occurs, re-calculate the
absorption distance, and determine if the SAM-e needs to be modified or relocated.
A. IN-DUCT INSTALLATION
(1) Without Mounting Frame
(a) Once you have selected the location of the manifold, use the supplied template
to cut out the holes for the steam inlet and condensate drain outlet.
CAUTION
DO NOT PULL OUT THE STEAM TUBES ONCE THEY HAVE BEEN
INSTALLED INTO THE HEADER. THIS COULD DAMAGE TO GASKET.
(b) Insert all steam tubes into the main header, until the flange is flush with the
rubber gasket. See Figure 16. Make sure that all nozzles offset each other by
rotating the tubes. See Figure 17.
NOTES
Appling water to the gasket will help to slide the tube into place. Do not lift the
manifold by the steam tube when installing.
i. Fasten the top steam tube bracket to secure all steam tubes using a bolt,
washer, and nut assembly. (Factory Supplied). See Figure 20.
ii. Fasten top steam tube bracket to the mounting frame using a bolt, washer,
and nut assembly. If a mounting frame is not available, follow the drawing
instructions in Figure 22.
iii. Insert the manifold into the duct and slide the steam inlet and condensate
drain into the cut out holes. Mark the location of the 4 hole of the header-
mounting bracket on the bottom of the duct.
iv. Drill 4 x 0.500 inch (12.7mm) holes at the marked location.
v. Fasten the header using a bolt, washer, and nut assembly (Field Supplied)
vi. Mount the field-supplied threaded rod to the top steam tube bracket to secure
the assembly in place or refer to „Installation with adjustable mounting frame‟
if mounting frame was provided. See Figure 22.
