MOUNTING IN AN AIR HANDLING UNIT
See placement recommendations in Figure 7-1.
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 1/4–20 nuts and bolts or #12 self drilling and tapping screws. Due to
the possible forces exerted on this application, DriSteem 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 humidifi er to
provide proper support. See Figure 12-2.
