The fresh air door is opened and closed by the motorized drive. Calibration, as
shown in Figure 10, will ensure the required amount of air, up to a maximum of 450
CFM, is delivered to the classroom.
Follow the directions in Figure 11 to ensure the proper air flow rate setting. After
calibrating the ventilation system, replace the lower front cabinet panel.

Note: Once calibrated, the manual fresh air system
door remains at the set opening at all times.
Inside the lower section, locate the circular calibration plates
as noted in the drawing (“A” is fixed, “B” is movable). Remove
the screw shown by the arrow from “Manual Settings.”
Rotate plate B in a clockwise direction until the hole from
which the screw was removed aligns with the hole adjacent
to the desired air flow rate, in CFM.
Reinsert the screw into the hole in plate B and firmly drive
the screw through the appropriate air flow rate hole, so plate
B is securely fastened at the desired opening.
Figure 10. Manual Fresh Air System Calibration Procedure
Inside the lower section, locate the circular calibration plates
as noted above in the drawing (“A” is fixed, “B” is movable).
Remove the screw shown by the arrow from “motorized settings.”
Reinsert the screw into the hole in plate B adjacent to the
desired air flow rate, in CFM, and firmly drive the screw in until
it bottoms out at the screw head.
Note: Motor drives plate B open to setting
when control relay (VMR) is energized.
Motor drives plate B to the closed position
when control relay (VMR) is deenergized.
Operation is the same for the "Motorized"
and "PowerVent" systems.
