Wiring

4.Use access-mounting plate as a template. Hold plate against duct and mark the four hole locations for attaching plate to duct. Be sure slotted hole in center of plate is over point “X” (Fig. 1) and that edge of plate is parallel with edge of duct. Then drill the four holes to take #10 sheet metal screws.

5.Cut out 4” x 8” access hole through which damper vane is to be installed. Access hole should be centrally located between the four mounting holes.

6.Attach indicator wheel to damper shaft with two 5-40 screws with lockwashers.

7.Cut damper vane to duct size, allowing 1⁄8” minimum clearance between duct and vane at all points. (If required, snip notches in vane to clear protruding sheet metal screws used to mount bearing plate.)

8.Attach vane brackets to locate damper shaft on exact center line of damper vane. (Dimension from center line of vane to center of holes for attaching vane brackets is 17⁄32”.) Then start 8-32 set screws into vane brackets.

9.Insert damper shaft through access-mounting plate, then through vane brackets. Holding indicator wheel flush against access-mounting plate, lock damper shaft to vane by tightening set screws, being sure to leave 1⁄8” minimum clearance between edge of vane and access-mounting plate as shown.

10.Install vane through hole in duct by turning vane sideways and slipping damper shaft into slot in bearing plate on opposite side of duct. Push indicator wheel flush against access-mounting plate and spin indica- tor wheel to assure free turning of vane. Then attach access-mounting plate to duct and cut off damper shaft so it extends 1” past bearing plate.

11.Motor is shipped in closed position. Turn indicator wheel so that yoke on bottom of motor slips into square holes on indicator wheel when motor is placed into position. Tighten motor firmly with wing nuts. (The word “closed” should be visible on the indicator wheel.)

All wiring must conform to local and national electri- cal codes.

For best connections, use #18 Thermostat wire. #16 will also work satisfactorily.

Make connections to screw terminals according to wiring diagram.

If the furnace manufacturer recommends a wiring dia- gram, follow such instructions. If none are available, the following diagrams show suggested circuits for Type 2061 Damper motors in conjunction with two-wire thermo- stats (.2 Amp anticipator) and other related controls.

NOTE

To check motor operation without thermostat connected, jumper 2 to 4 to open motor. Remove jumper to close motor.

The WR S81-0125 Transformer (40 VA) will handle up to 4 damper motors. The WR S81-0126 (20VA) will handle up to 2 damper motors.
