Anleitung Zusammenfassung
1. Insulating the Duct The ductwork must be insulated a minimum of 6 in. (152mm) on the damper side and 18 in. (457mm) on the non-damper side (see figures 1-4). Any US Coast Guard type approved insulation with an A60 rating can be used. The insulation is to be installed on the duct with 0.106 in. (2.7mm) steel pins and 1.12 in. x 1.24 in. x 0.4 in. (28mm x 31mm x 10mm) steel clips. 2. Attaching Damper to Duct The damper can be installed to the duct using either bolts or welding. If bolts are used , they are to be a minimum of 0.375 in. (9.5mm) diameter and 1 in. (25mm) long. The fasteners should be spaced 6 in. (152mm) OC and a maximum of 2 in. (51mm) from the corners. Horizontal Airflow- Vertical Damper mount IF HEIGHT <=11.00 in.

(813mm x 813mm) (1626mm x 813mm) Manually operated dampers (IMO-310 & SSIMO-310) Manually operated dampers utilize a spring and fusible link assembly to close the damper during elevated temperature conditions. No electrical power is required for these models. Motor operated dampers (IMO-311 & SSIMO-311) Motor operated dampers are supplied with an electric thermal response device which cuts power to the spring return actuator upon sensing an elevated temperatures. See below for electrical connections.

The device is a RRL (resettable link device), which only incorporates one thermostat and therefore the damper remains closed as soon as its sensor temperature is reached. The RRL does not contain blade indication switches. Refer to Figure 5 for wiring of the RRL thermostat. If RRL is ordered with a pneumatic actuator, an EP switch is required with an appropriate electric power circuit to allow the electric thermostat to control the pneumatic actuator. OCI - The OCI (open or closed indicator) option contains a single pole, double throw switch used to indicate the damper blade position. The switch provides a positive open or closed signal when used in conjunction with remote indicator lights. Refer to Fig. 7 for wiring of the OCI option. PRV - The PRV (pneumatic relief valve) option is heat responsive device used with pneumatic actuators. This can be used in place of EP switch where a RRL is used. The PRV activates when temperature in excess of the temperature of the fusible link are detected. When the fusible link melts, air from the actuator is exhausted to close the dampers. Pneumatic actuators are to be piped per local code. RRL Wiring Fig. 5 L1DAMPERINDICATORLIGHTSL2CLOSED POSITION OF THE DAMPER.

If cleaning is necessary, use mild detergents or solvents. If lubrication is desired for components such as axle bearings, jackshaft bearings and jamb seals, do not use oil-based lubricants or any other lubricants that attract contaminants such as dust. Dampers and their actuator(s) must be maintained, cycled, and tested in accordance with: • The latest editions of NFPA 80, 90A, 92A, UL864, and local codes. • Actuator manufacturer recommendations. Damper Trouble Shooting The following is a possible cause and correction list for common concerns with the dampers. Symptom Possible Cause Corrective Action Frame is ‘racked’ causing blades to Adjust frame such that it is square bind on jamb seals and plumb Actuator linkage loose Close damper, disconnect power, adjust and tighten linkage Defective motor Replace Screws in damper linkage Locate screws and remove Actuator linkage hitting wall or floor Damper installed too far into wall.
