(NOT work with Honeywell ZD Rectangular Dampers)

DuroZone #35105 damper Motor & similar HVAC spring-return 2-wire damper actuators by Zone First, Erie, and others.

Specifications:
Voltage: 24vac ± 10%, 60 Hz, 0.36A
Torque Rating: Power open 32 in. oz./spring close 32 in. oz. - torque is consistently delivered throughout the full 90° rotational operating range to open and close the damper, irrespective of whether the actuator is operating in Power Advance Mode (energized) or Spring Return Mode (de-energized)
Speed Stroke: Motor driven 30 sec./spring return 6 sec.
Rotating Angle: 93.5°
Noise Level: Very quiet operation, typically ≦ 40dB at 3'
Reliability: Statistical life reliability exceeds 120,000 cycles at 90% reliability and 100% confidence with no decay in delivery torque over the life of the actuator

Installation:
Step 1: Disconnect the power supply before connecting the motor wiring to prevent electrical shock or equipment damage.
Step 2: Using a hex wrench, loosen the motor coupling from the blade shaft and remove the existing motor assembly.
Step 3: Ensure that the damper blades are in the correct installation position.
Step 4: Loosen the set screw on the motor collar.
Step 5: Place the actuator onto the damper shaft and insert the anti-rotation pin into the anti-rotation pin hole.
Step 6: Double check that your damper blade and shaft are in the correct installation position for your application, then lock the collar onto the damper shaft by tightening the set screw on the collar.
Step 7: Reconnect the motor wiring.
