Greenheck ABD-Z2 User manual

Receiving and Handling
Upon receiving dampers, check for both obvious
and hidden damage. If damage is found, record all
necessary information on the bill of lading and file
a claim with the final carrier. Check to be sure that
all parts of the shipment, including accessories, are
accounted for.
Dampers must be kept dry and clean. Indoor storage
and protection from dirt, dust and the weather is
highly recommended. Do not store at temperatures in
excess of 100°F (38°C).
This manual is the property of the owner and is required for future maintenance. Please leave it with the owner when
the job is complete.
Safety Warning
Improper installation, adjustment, alteration, service
or maintenance can cause property damage, injury
or death. Read the installation, operating, and
maintenance instructions thoroughly before installing
or servicing this equipment.

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.
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).
