Installation inside an air handling unit
See placement recommendation in Figure 11-1.
The metal support frame should be anchored to the air handler
casing. Recommended fasteners for mounting the Ultra-sorb to a
metal support frame are ¼ - 20 nuts and bolts or #12 self drilling
and tapping screws. Due to the possible forces exerted on this
application, DRI-STEEM recommends fastener spacing not to
exceed 6" (150 mm). On larger Ultra-sorb installations, vertical
channels may be required on both the inlet and outlet ends of the
humidifier to provide proper support. See Figure 15-2.
