General Installation
Electrical Guidelines
All wiring shall be done in accordance with the National Electrical Code
ANSI/NFPA-70 latest edition, any local codes that may apply, and wiring
diagrams developed in compliance with the job or project design and
specifications.
Important!
Electrical input may be needed for this equipment. This work should be
performed by a qualified electrician. Verify power before wiring actuator.
Greenheck is not responsible for any damage to, or failure of the unit caused
by incorrect field wiring. To avoid causing death or serious bodily harm to
building occupants, follow all instructions carefully. Dampers must close
completely to preserve the integrity of the fire smoke separation.
Setting Desired CFM on the ABD Damper
Verify the minimum and maximum setpoints are in the available range (see
Figure 3 and 4).
Adjusting the Minimum CFM
Loosen the bolt to adjust to move drive link to primary or alternate linkage
location. See Detail A for correct linkage location.
Adjusting the Maximum CFM
How the maximum CFM adjusted. Loosen the wing nut on crank arm, adjust full-
open stop clockwise until specified maximum CFM setpoint is achieved. Tighten
wing nut.
Note: ABD-Z2 is adjustable in the field. Make sure full open stop does
not over travel. If you over adjust, you can wreck the unit.

Mounting the ABD-Z2 in the Ceiling
- Attach the hanger brackets provided to the damper. Dampers shall be supported in a minimum of two places on opposite sides of the damper.
- Insert the ABD-Z2 between the ceiling joists. Attach the hangers to the ceiling joist using 2 – #8 x 3 ⁄4 in. nails.
- Attach the ductwork to the collar of the plenum box.
- Install the grille.
Actuator Connections
Electrical connections to damper actuators should be made in accordance with
wiring and piping diagrams developed in compliance with applicable codes,
ordinances and regulations (see Electrical Guidelines).
Damper Maintenance
Dampers do not typically require maintenance as long as they are kept dry and
clean. If cleaning is necessary, wash with water. No solvents should be used
in cleaning, as they could damage the valve or gasket. In addition, ABD
dampers incorporate Steri-BalanceTM into all plastic components. Steri-
BalanceTM is a non-caustic material that inhibits antimicrobial growth.
