NOTE: Install filters so that “Air Flow” arrows point toward the unit.

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

CAUTION: 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.

9.The enthalpy set point for the dampers may now be set by selecting the desired set point from graph in Figure 8. For a single enthalpy economizer, carefully turn the set point ad- justing screw to the “A”, “B”, “C” or “D” setting correspond- ing 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.

11. Replace the filter section access panel. FIG. 8 - ENTHALPY SET POINT ADJUSTMENT
