Before Installing Damper in the Duct

If the damper has more than one blade, determine which blade axle will be driven by the extended control shaft. Always attach extended control shaft to a blade axle which is directly connected to the main linkage tiebar. DO NOT attach extended control shaft to a crossover blade axle.
Cut hole approximately 1 in. (25 mm) diameter in duct where the damper drive blade axle will be located. Hole must provide clearance for enlarged portion of extended control shaft.

After Damper is Installed in the Duct

Push extended control shaft through the hole in the duct and onto the drive blade axle. Retainer clip should “click” into groove on the drive blade axle and hold the shaft into place.
- Standard control shaft location in the third blade from the bottom on dampers with three or more blades. Control shaft location is the first blade from the bottom on dampers with one or two blades.

Non-Jackshafted Dampers

Control damper should be mounted in the duct and the shaft extension mounted onto the correct blade of the damper before continuing with these instructions.

After Extended Shaft is Installed

The jackshaft is either 1⁄2 in. or 1 in. diameter depending upon the size of the damper. The manual quadrant kit for the 1⁄2 in. diameter jackshaft is part number 865086 and the manual quadrant kit for a 1 in. diameter jackshaft is part number 862239.
With the damper either fully open or closed, lock the manual quadrant to the jackshaft so the manual quadrants can move the damper between open and closed. Note: Tighten down the bolt on the manual quadrant to 250 in. lb. of torque. Apply “OPEN” and “CLOSED” labels if the damper movement is opposite to what is engraved on the manual quadrant.
Set the damper to the desired position and tighten the wing nut on the manual quadrant to hold the damper in place.
