FIELD INSTALLATION INSTRUCTIONS

NOTE: FOR DAMPERS

INSTALLED IN DUCTS

Extended Control Shaft is

installed from outside of duct after damper is installed. Install as shown below.

Crossover Blade Axle (Do not attach Control Shaft here!)

Before Installing Damper in the Duct

1. If 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.

2. Cut hole approximately 1 in. (25mm) diameter in duct where damper drive blade axle will be located. Hole must provide clearance for enlarged portion of extended control shaft.

After Damper Is Installed in Duct

1. Push extended control shaft through hole in duct and onto drive blade axle. Retainer clip should "click" into groove on drive blade axle and hold shaft into place.

Standard Control Shaft location is 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.

2. Install the stand off bracket with bearing over the extended control shaft and screw bracket to duct. Make sure screws (provided by others) do not interfere with damper linkage or blade movement.

Caution Stand off bracket with bearing is needed to support

the extended control shaft. If not installed as directed, the extended control shaft may not operate the damper correctly.

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

1. Assemble Manual Quadrant to extension bracket assembly (screws provided).

2. With damper either fully open or closed, lock manual quadrant to extended control shaft so manual quadrant can move damper between open and closed. Note: Tighten down bolt on manual quadrant to 250 in. lb. of torque. Apply "OPEN" and "CLOSED" labels if damper movement is opposite to that engraved in the manual quadrant.

Jackshafted Dampers

1. The jackshaft is, either, 1⁄2 in. diameter or 1 in. diameter depending upon the size of the damper. The manual quadrant kit for the 1⁄2 in. diameter jackshaft is Part #811518 and the manual quadrant kit for a 1 in. diameter jackshaft is Part #813938.

2. With damper either fully open or closed, lock manual quadrant to jackshaft so manual quadrant can move damper between open and closed. Note: Tighten down bolt on manual quadrant to 250 in. lb. of torque. Apply "OPEN" and "CLOSED" labels if damper movement is opposite to that engraved in the manual quadrant.

3. Set damper to desired position and tighten wing nut on manual quadrant to hold damper in place.
