Install filter cover over the end of the hood with one
screw (center of hood), securing filters into position.

The enthalpy set point for the dampers may now be set
by selecting the desired set-point from graph in Figure 4.
For a single enthalpy economizer, carefully turn the set-
point adjusting screw to the “A”, “B”, “C” or “D” setting
corresponding to the lettered curve. For a dual enthalpy
economizer, carefully turn the set-point adjusting screw
fully clockwise past the “D” setting.
10. To check that the damper blades move smoothly without
binding, carefully turn the minimum position adjusting
screw fully clockwise and then energize and de-energize
terminals “R” to “G”. With terminals “R” to “G” energized,
turn the minimum position screw counterclockwise until
the desired minimum position has been attained.
Replace the filter section access panel.
When proceeding with steps 9 and 10, extreme
care must be exercised while turning both the set
point and minimum position adjusting screws to
prevent twisting them off.
