Actuator Specifications
The MP-100A motor pack uses a single phase, 60hz,
shaded pole, stall type impedance protected electric
actuator. Specific model depends on the voltage selected.

MP-100A Motor Pack
UL Listed Electric Actuators With Spring Return
For Use With WD-100 Series Dampers
1. The MP-100A motor pack is designed for installation on
Model WD-100 backdraft dampers only. When properly
installed, the damper will be horizontally mounted (air flow
up) and the motor pack will be on top of the damper.
2. Attach connecting link(s) to the damper link using the #10
hardware along with the bronze bushing(s) (see detail
“ B”).
Use position
“ A” on most applications. Position “B” can be
used on larger dampers when a negative pressure is
present. The damper blades can be lifted to the open
position to provide easier access when attaching the
connecting link(s) to the damper link. Tighten all fasteners.
Note: Check that the connecting links are over the
bushing(s) and not pinched between the end of the bushing
and the screw or damper link.
3. Attach the motor pack assembly to the damper frame with
the 1/4 in. hardware provided. Assemble the connecting
link(s) to the actuator arm assembly using the #10
hardware. The damper blades should be closed during this
connection. The angle between the connecting links and
the actuator arm should be approximately 135 degrees with
a slight tension on the spring. Tighten the fasteners
between the connecting link and the actuator arm
assembly. Fasteners should be placed as far apart as
possible. This will provide greater stability to the linkage.
Operate the damper manually. Verify that the linkage
fasteners do not interfere with any components of the
assembly and that the damper blades close completely
when released.
Note: The spring can be adjusted to provide more or less
closing force. It is important not to use too much spring
tension; use just enough to help close the damper. Too
much tension could impair damper opening.
To adjust the spring, unhook the spring from the actuator
bracket and reattach to the next hole that provides more or
less tension.
4. Actuators are supplied with junction boxes and covers.
When wiring, make sure the supply voltage agrees with the
actuator voltage. Voltages are stamped on the bottom of all
actuators under the output shaft (see page 2 for typical
wiring diagrams).
5. If the damper fails to operate properly, check for one of the
following causes:
•Check for an ‘out of square’ or racked damper.
•Check for mounting screws interfering with the
blade and linkage rotation.
•Spring tension too great.
•Excessive voltage drop.
•Excessive negative pressure in the building.
If the motor pack fails to function:
•Check for correct voltage.
•Check for proper wiring.

Greenheck's MP-100A motor packs utilize single phase, 60 HZ (50 HZ optional) damper actuators and are supplied in one of
the following voltages: 24, 115, 220, or 440 volts. The voltage of the actuator is stamped into the housing near the output shaft.
For 208, 277, 575 or 600 volt operation, an optional transformer and a 115 volt motor pack is required.
1. Diagrams are shown for motor packs and dampers installed with powered ventilator fan equipped with a single speed
motor. The damper will open when the fan is on and close when the fan is off. For connection to 2-speed motors or for
other control sequences consult the factory.
2. Diagrams shown with end switches are for applications where it is desirable to have the damper fully open before fan
start-up.
