INSTALLATION

1.

Unpack the damper and install into ductwork.

NOTE: For insulated duct, slide the insulation under the actuator and tape it to the actuator’s outside flange to seal.

NOTE: In unconditioned spaces, mount the actuator only on the side or top of the damper. Mounting on the bottom of the damper may result in condensation dripping into the actuator.

2.

Set the range stop to the desired position.

Position 0 means fully closed.

NOTE: On ARD/ZD models, range stops prevent full closure. On EARD model, range stop prevents full open.

3.

Wire the actuator. See “Typical Wiring Examples” on page 2.

a. For 2 wire usage, wire M1 and M6. See Fig. 1.

b. For 3 wire usage, break the plastic tab to

access M4. See Fig. 2.

c. For EARD wiring, use only 2 VENT terminals.

Closed

NOTE: To have the lights and position indicator be accurate, you would need to replace the

M847D-ZONE actuator with the M847D-

VENT actuator. If this is installed in an attic or crawlspace which is not visible to the customer, and having the lights and indicator be reversed is not a concern to you, the M847D-

ZONE actuator can be used. The EARD dampers come from the factory as spring-closed/ power-open dampers.

1.

Remove the actuator.

2.

Locate the two plastic grommets on the damper and move them from one side to other.

3.

Rotate the damper to closed position.

4.

Replace the actuator on the opposite side of the damper.
