The damper operates on a 3-wire power-open and power-closed configuration, driven by a motor rated at 17 inch-pounds of torque. A manual gear release and onboard fail-safe LEDs support fast field diagnostics during installation and service calls. Nylon bushings reduce operating noise, and overlapping blades with a strong positive-off motor deliver a 97 percent leak-proof seal for accurate zone airflow control.\u003c\/p\u003e\u003cp\u003eThis damper is sized for 8-inch by 14-inch rectangular ductwork and integrates directly into EWC Ultra-Zone zoning systems. The LED display lets the installing technician visually verify damper blade position without additional test equipment. A quick-connecting terminal block eliminates the need for wire connectors and speeds up field wiring. The sturdier frame design reduces installation time in tight duct chases. This damper is a fit for forced-air zoning retrofits and new construction zone control applications handled by HVAC technicians.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3-wire power-open and power-closed motor operation with manual gear release\u003c\/li\u003e\n\u003cli\u003eMotor driven at 17 inch-pounds of torque for reliable blade actuation\u003c\/li\u003e\n\u003cli\u003e97 percent leak-proof rating via overlapping blade design and positive-off motor\u003c\/li\u003e\n\u003cli\u003eOnboard fail-safe LEDs for quick diagnostic checks during checkout\u003c\/li\u003e\n\u003cli\u003eNylon bushings for quieter operation and extended motor service life\u003c\/li\u003e\n\u003cli\u003eQuick-connecting terminal block eliminates wire connectors and speeds wiring\u003c\/li\u003e\n\u003cli\u003eUL listed and NEMA Class 2 certified motor\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with EWC Ultra-Zone zoning systems and sized for 8-inch by 14-inch rectangular duct installations.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed HVAC technician familiar with forced-air zoning controls. De-energize the air handler and zoning control panel before connecting or disconnecting any wiring at the terminal block.
