NOTES:
1. Damper shaft moves 90 degrees from open to close.
2. Operating torques are shown for one damper. Multiply the value shown by the number of dampers for total with one actuator.
Zone Damper Section —
the section as follows:
1. Remove the screws holding the zone damper section to
the heating coil section and remove the lag screws
holding the damper to the shipping skid.
2. Place the supplied /

gasket around the perimeter of the cooling and heating
coil section discharges. Use two gasket strips on parti-
tion panels to obtain double width.
3. Rig the zone damper section and lift it into position on
(vertical discharge) or next to (horizontal discharge)
the gasketed cooling and heating coil sections.
4. Fasten the damper section to the coil sections using the
supplied / -14 x / -in. sheet metal screws.

5. Install control shaft and bearing for each individual
zone after cutting linkage (for the job specific zone
application).
Control shaft extensions are bagged and wrapped to
the inside of the zone damper blades. Additional field-
supplied shaft extensions may be ordered from local
Ruskin supplier, part no. 10-020569-00B.
6. Zones should be split for equal airflow through each
damper.

Factory duct collars and damper assemblies are for attach-
ing ductwork only and must NOT be used to support the
duct's weight. Weight bearing deflection can increase
torque necessary to operated dampers, or bind them pre-
venting any movement.
ZONE DAMPER LINKAGE (FIG. 37 AND 38) — Note
that damper control levers and a common operating bar are fac-
tory installed on upper end of damper shafts on top of zoning
damper assembly. To facilitate the installation of field-supplied
damper operators, the operating bar may be cut and the control
levers repositioned as follows:
Damper operation may be impaired if ductwork is
supported by the unit.
1. Check job prints to determine number and size of
zones required and damper operator locations.
2. Cut and remove portion of operating bar between
zones as required.
3. Install actuators on field-fabricated support brackets.
Connect actuator linkage to the center axle of intercon-
necting zones.
4. Adjust actuator for correct damper operation. Be sure
actuator, linkage, and dampers operate freely. See
Table 27 for operating torque requirements.
