Kit Part No. DAMPA(_T45DE(_-R and DAMPA(_TgODEG-R are the replacemeut actuators desigued ]i_r resideraia] dampers. These kits couIain

the aciuator, au auti-rotaIkm mouuIing screw, al-_dan Installation hlstruction. They caT1be used on dampers having rouud shales or the newer dua_

llalted shalts. The 24-vac direct-drive actuaor provides smooth, qlliet per%rmgmce in a smalter package. The DAMPACT45DEG-R kit is inIended

lot round and newer rectangular dampers having a 45 degree rotation lrom closed to open. The DAMPACT90DEG-R kit is for slip-in and okler

reclangu_ar dampers which rotate through 90 degrees h'om closed to open. Ninety degree rectangular dampers have round shalis while 45 degree

rectangular dampers have dua] flatted shafts with an arrow on tl_e shali end.

Z_ CAUTION: UNiT OPERATIONAL HAZARD

Failure to follow this caution may result in improper unit operation. An operational problem will occur if the wrong travel

actuator is applied to the wrong damper. Use DAMPACT45DEG-R for 45 degree dampers and DAMPAOTg0DEG-R for 90

degree dampers.

ACTUATOR FEATURES

1. A l/2-in, direct-drive mouuting hub lor securing damper blade and shall to :lcttmtor housil/g.

2. Spriug-loaded disengagemeuI (quick blade re_ease burma) lk_rmomentary release of main gear arid damper blade.

---> 3. Recessed termiua_ block wiring.

INSTALLATION

Repb_cing tl_edamper actmttor can be perR_rmed on dampers ah'eady installed ill ihe duct system. Dampers shoaM _t_'_' _t_rS be iustalled v, here the

actuator is visible lbr inspection and accessible lbr serviciug. A black marker line or a molded arrow on the end ol the damper shali can be used

to indicate the damper blade position.

REMOVE OLD ACTUATOR:

I. Turn power oil

2. Discom_ect 24-v wiring to damper actuator.

3. Completely remove oM aciuator assembly and irloul_tir_g bracket i}om damper.

NOTE: Alter actuator assembly is removed the damper shaft and blade shoukl move freely withil_ housil_g. [1 bindil_g or stickil_g occurs, problem

must be corrected befbm il_staHil_g new actuator.

TO INSTALL REPLACEMENT ACTUATOR:

---> NOTE: Both the 45 al_d 90 degree replacemem actuators will mecharfically rotate a ful! 90 degrees whel-_ the blade release button is pressed. The

45 degree actuator uses the blade as a mechal-dcal stop to stop it at the closed positi<m, so that it only rotates through 45 degrees when cormected

to the damper. This is the way it is desig!_ed to operate. Follow directions below, attaching tl_e actuator to the shaft at the fu]ll open position.

I. h_stall new actuator aligl_ing shali through mouluing hub (do not tighten set screw yet).

2. Fasten actuator to the damper by using the mai-rotation screw supplied it* packaging.

---> 3. For round shaft dampers, aligl-_ the damper Nade to the li_![y opel_ position ir_dicated by a Nack Hl_e on the shall end paral]e[ io the air flow

direciion. The actuator sholfld be in ihe lully cormier-clockwise position. Check by pressing the gear release breton al_d manHally rotating

the actuator to the [_/lly CCW stop. Slide the actuator up the shaJ) away from the damper by 3/16 inch to make its base paraHe_ to the damper

sin:lace. Now securely tighten the set screw using a 5/!6 open el-_d wrench.

For flaited shaft dampers, slide ibe actuator over the shall slip the actuator up the shah 3/16 inch to make its base parallel to the damper

surlace arid tighien the set screw agail_st the CCW liar on the shaft. This will automatically aligl_ the shaft and actuator.

--€ 4. To wire damper, strip wire _eads 1/4 inch, il-_sert inlo appropriate terminal al_d tighten terminal screw. It is good practice to provide a wiring

strain re]iel to protect co[lllection JroH1 wire irloveli]e[lt,

5. After insta_iatkm is cnlrlp_ete, check dampers and verify they are all operatil_g properly. Press in the Quick Blade Release (usil_g one halx!).

This will disengage the damper blade. Use your other hand to turn II_e monluil-_g hub back and %rth several times to insure the damper blade

is moving freely inside ol duct. ]li doeslFt matier what position you leave the monntil_g hub, because the system will provide proper

positiol-_il-_g. Power damper and cycle operdclosed several times. Resideluial dampers are desig!_ed il-tsHcha way tl_at if the blade jams or

stalls it wil_ m_t damage ihe damper or motor. Ill lbr any reason the damper should .}alrl, it will usually be related to twistil_g or bending of

the damper body durh_g instalhtiom or tension or* the damper shaft.

6. ll_ areas where excessive condensil_g may occur, careltflly insulate over the aciuator assembly. Make sure ir_sulatiol_ does not ilaerli:re with

operatior_ of actuator.
