EDA-8000 Product/Technical Bulletin 5
Standard Mounting
The EDA-8000 is not position sensitive and can be
mounted in any convenient orientation on a duct or wall
that is 16 gauge (0.06 inch or 1.5 mm) or thicker as
long as the drive shaft is perpendicular to the mounting
surface of the actuator.

Figure 7: Actuator Against Duct
1.
Position the actuator onto the blade pin extension
so that the actuator sits against the duct as shown
in Figure 7.
Note:
The bottom center mounting hole looks the
same as the top mounting hole illustrated in
Figure 7.
2.
Use of the actuator’s center mounting slots with
the isolation grommets is the preferred mounting
arrangement. If the duct or wall is less than
16 gauge (0.06 inch or 1.5 mm), use the
Universal Mounting Bracket (D-3153-105).
Note:
Because of eccentric motion of the actuator
that occurs when using shafts smaller than
10 mm (0.394 inch) square or 1/2 inch
(12.5 mm) round, use the isolation grommet
only in the bottom center mounting slot.
3.
Mark the location of the actuator’s top and bottom
mounting slots on the duct or wall.
4.
Remove the actuator and coupler and set aside.
5.
Drill two 5/32 inch (4 mm) holes in the duct or wall
at the marked locations.
Note:
When using the universal mounting bracket,
drill two 11/64 inch holes.
6.
Slide the actuator and coupler onto the pin
extension.
7.
Secure the actuator to the wall or duct with the
screws and isolation grommets included in the kit.
8.
Tighten the two square-head screws on the
actuator coupler.
9.
Lift the manual release lever and hand turn the
coupler CW and CCW to check that the damper
blades fully open and close.
Note:
The cover should remain off until the wiring is
completed.
