Figure 15: Mounting Process – Step 6
Fix one mounting bracket “H” to each vertical support and intermediate support using a
hexagon socket screw 1/4 UNC x 1/2", a 1/4 UNC nut and a washer (see figure above).
Important: With multiple intermediate supports all mounting brackets must be mounted to the
supports on the same side. Having only one bracket, on the inside of each section, allows
easier humidification box insertion and removal. The mounting brackets fixed to the
outermost supports must be mounted always outside (between duct wall and support) and
point inward.
Finally align the supports, then fix the mounting brackets to the duct ceiling using two self-
tapping screws 1/4 UNC x 3/4" each.
