Electrical Guidelines
RBD & RBDR Series dampers are driven by a 9 volt
actuator. The 9 volt power is supplied from a Greenheck
"EZ Balance" hand held remote. The "EZ Balance"
remote is plugged into a wall or ceiling jack that is
wired to the damper actuator using wire and connector
assemblies.
After the damper and wiring is installed, operation of
the damper and wiring circuit must be visually verified
by connecting the "EZ Balance" remote to the wall jack
and power up the unit. Using the switch on the "EZ
Balance" remote, run the damper through a complete
cycle from full close to full open and reverse back to
closed position. Document that proper operation has
been verified.
Installation Instructions
Round, RBDR series, dampers are supplied from the
factory with the actuator installed, see Figure 1.
Square/rectangular, RBD series, dampers are supplied
with an actuator kit that must be field installed as
follows:
1) Install the RBD series damper into the ductwork with
the lanced end of the blade positioned to the side
of the duct where the actuator is to be located (see
Figure 2).
2) Drill a minimum
⁄
in. (14mm) diameter hole that lines

16
up with the center pivot of the damper blade
3) Insert the pointed end of the pin through the hole
and into the blade lances. Pound pin into the blade
lances until the end of hte pin is
of the duct surface whilc the blade is centered in the
damper frame.

4) With the blade closed, install the actuator by aligning
the coupler over the end of the square pin (as shown
in Figure 2) and sliding the actuator assembly onto
the pin until the bracket is in contact with the duct
surface.
5) Check the blade clearance to be sure that the blade
can move side to side in the frame and it is not
pressed against the opposite side of the damper
frame. If the blade is pressed against the opposite
side, the pin may need to be pounded a little further
into the blade.
6) Connect a Greenheck EZ Balance control device to
the actuator. While holding the actuator assembly
against the duct, press and hold the "Close" button
until the "full closed" light flashes.
7) Rotate the actuator assembly to hold the blade
closed then secure the actuator to the duct using the
two supplied screws.
8) Recheck the blade clearance and damper operation
by cycling the actuator.
9) All wire connections from the wall or ceiling jack
to the damper actuator must be secured to the
building structure in such a way as to prevent strain
on the wire connections (for example: use wire
ties to secure a wire loop at each connection and
intermittently between the connections).
10) The actuator mounting bracket has a factory
installed wire tie for the purpose of providing strain
relief at the actuator. Thread the wire through the
wire tie, loop around and back through the wire tie
before connecting to the actuator box. Tighten the
wire tie leaving a short loop at the actuator.
