Preparation for the Roof Exhauster Installation
Using the roof exhauster mounting plate, some preparations are required for the roof panels to which the
roof exhauster mounting plate will be installed.
Before You Begin
Determine the location of the roof exhauster and set aside the roof panels that the roof exhauster
mounting plate will span.
What You Should Know
This procedure is to cut the exhauster airflow hole. Use the roof exhauster mounting plate as a template
to determine the correct location for field cutting the roof exhauster hole.
1. Position the roof panels (77) spanned by the roof exhauster mounting plate (75) on the ground.
Align the roof panel holes as if they are installed on the bin.
2. Temporarily install the roof exhauster mounting plate (75) to the roof panels (77) using 5/16" x 1"
flange bolts (1) and 5/16" flange nuts (10). Make sure all the holes are aligned and the teeth of the
roof exhauster mounting plate (75) are nestled in between two roof ribs. Also field drill all required
holes on the roof panels (77).
3. Using the roof exhauster mounting plate (75), mark or scribe the hole (78) to be cut.
Tip
If tabs are already bent, flip the mounting plate (75) upside down to scribe the hole location.
