3. SAM-e SHORT ABSORPTION MANIFOLD
NOTES
1. Absorption distance is the minimum distance an obstruction can be placed
downstream of the SAM-e to prevent steam condensing on the obstruction.
2. If any of the ducts of the AHU conditions are changed, the absorption distance
may change due to increase or decrease in duct temperatures, 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 INSTALLED, THIS COULD
DAMAGE THE GASKET.
(b) Insert all steam tubes into the main header, until flange is flush with rubber gasket.
See Figure 20. Make sure all nozzles offset each other by rotating steam tubes.
See Figure 21.
NOTES
1. Applying water to the gasket will help to slide the steam tube into
place.
2. Do not lift manifold by steam tubes when installing.
(c) Fasten the top steam tube bracket to secure all steam tubes using a bolt, washer
and nut assembly. (Factory supplied). See Figure 22.
(d) Fasten top steam tube bracket to mounting frame using a bolt, washer, and nut
assembly. If mounting frame is not available, follow drawing instructions in
Figure 24.
(e) Insert the manifold into the duct and slide the steam outlet and condensate drain
into the cut out holes. Mark the location of the four holes of the header mounting
brackets to the bottom of the duct.
(f) Drill 4 x 0.500 in. (12.7 mm) holes at the marked locations.
(g) Fasten header using a bolt, washer, and nut assembly (field supplied).
(h) Mount the field supplied 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 24.
(2) WITH ADJUSTABLE MOUNTING FRAME (Optional, see Figure 23)
(a) Insert the sliding panel into the base.
