Normally Closed Drive Ear Mounting. INSTALLATION General The MP909 Damper Actuator can be installed externally or internally.There are two mounting approaches: standard and nonstandard. Use nonstandard mounting when standard mounting is not practical (e.g., for extra clearance or non- Honeywell dampers). It can require ordering additional parts. Standard Mounting External Mounting ANGLE BRACKET MOUNTING NOTE: For dampers with 1/2 in. (13 mm) diameter shaft extension to outside of duct, angle brackets and hardware are furnished with certain MP909E and H models. For shaft extensions other than 1/2 in. (13 mm) diameter, an appropriate crankarm must be ordered (see Table 1). Table 1. MP909E and H Crankarms. Part Number Drive Shaft Diameter in in. (mm) Maximum Crankarm Radius in in.

Mark holes using the “B” holes of the bracket template enclosed with the actuator (Fig. 5): a. Unfold template and remove paper backing. b. Determine damper drive axle direction from normal position. c. Install template with appropriate axle hole on template over damper drive axle. Arrow surrounding hole should match rotation determined in step b. d. Press template against duct so that it adheres. e. Punch mounting holes. f. Screw mounting bracket, with actuator, firmly to duct with screws provided. g. Secure linkage to actuator and damper drive axle (see Fig. 6). NOTE: To provide proper pivot action, align push rod and actuator shaft at start of stroke. 3. Stroke actuator to check damper operation by applying air pressure to actuator. Readjust linkage if necessary. NOTES: • Two MP909E models (2.5 to 6.5 psi [17 to 45 kPa] and 9 to 13 psi [62 to 90 kPa]) achieve a 3-1/8 in. (80 mm) stroke. This results in 78 degree damper blade rotation. • To achieve 90 degree rotation, change the external damper crankarrn from a 2-1/2 in. (63.5 mm) radius to a 2-1/16 in. (52 mm) radius. • For modulating control, 78-degree blade rotation provides improved control and usually adequate maximum airflow. 95-7366—2 2 MP909E,H PNEUMATIC DAMPER ACTUATORS 8-7/8 (225) 1 (25) 4-1/2 (114) 2-1/2 (64) 5 (127) 6-3/4 (171) 13-5/8 (352) MP909E,H M17465 1 1 DOTTED LINES APPLY TO MP909H ONLY.

Alternate Top-Mount Crankarm Installation. JACKSHAFT INSTALLATION Installation procedures follow for mounting the jackshaft and kits. Three ways of mounting an actuator using the jackshaft kits are also included: Internal Damper Frame Mounting, Internal Duct Floor Mounting, and External Mounting. Damper jackshaft installation uses combinations of three separate kits for different installations (illustrated in Fig. 22 and 23). Fig. 24 and 25 illustrate typical installations for nor mally closed or normally open dampers. Review these figures carefully before installing. The jackshaft itself must be provided locally and meet the following specifications: — Must be 3/4 in. (nominal) galvanized steel pipe, schedule 40 (standard) thickness. — Can be of one continuous length, or made up of shorter lengths joined by threaded pipe ends using standard threaded couplings. — Couplings and pipe ends must be drilled through and locked together with bolts. 1.

Attach support brackets from end kit and modular kit(s) to sides of damper frame. NOTE: Mounting holes in brackets will match holes in the frame at only one location. (See Fig. 24 and 25.) 3. Insert snap bearings from kits into brackets. 4. Cut jackshaft to length. Smooth off rough edges. 5. Install jackshaft and crankarrns. NOTE: Be sure to install crankarms from operator kits. 6.
