ULTRA-SORB MODEL XV INSTALLATION, OPERATION, AND MAINTENANCE MANUAL
Notes:
1. Dashed lines indicate provided by installer.
2. See Figures 12-1 and 12-2 for trap clearance alternatives.
3. Steam supply line to unit and piping are not included.
4. Dispersion tubes are available on 3", 4", 6", 9" and 12" (76, 102 152, 229, and 305 mm)
centers.
5. Ultra-sorb steam dispersion panels will be assembled, crated, and shipped intact in all sizes
up to 98" (2490 mm) overall height. Any Ultra-sorb can be shipped unassembled by request,
requiring fi eld assembly.
6. Standard sizes are 12" x 12" up to 144" x 144" in 1" increments (305 x 305 mm up to 3660
x 3660 mm in 25 mm increments).
Larger sizes are available.
7. Heat exchanger requires 5 psig (35 kPa) minimum steam pressure.
Mounting in an air handling unit
• Metal support frames should be anchored to the air handler casing.
• Drill or screw through the header assembly only where shown in Figure 10-1. Screws and drill
bits must not penetrate more than 3/4" (20 mm) into the header assembly.
• Use 1/4–20 nuts and bolts or #12 self drilling and tapping screws.
• Fastener spacing should not to exceed 6" (150 mm).
• When Ultra-sorb Model XV is installed in bypass air applications provide additional bracing for
the unsupported side(s).
• Install the panel level. If slope cannot be avoided, ensure that the slope is toward the drain end
of the panel.
