If access to the damper shaft is limited, or internal
mounting is required, mount the actuator remotely by
installing a six inch long, 1/2 inch diameter rod into the
coupler and use linkage accessories shown in the
Damper Accessory Kits

CAUTIONS:
●
Follow NEC and local electrical codes.
●
Disconnect power supplies.
●
Observe the ranges and limitations found in
Specifications.
●
Do not install the actuator in applications
where its failure could result in personal injury
and/or loss of property.
●
Do not install if explosive vapors, corrosive
vapors, or escaping gases will be present.
●
Add protective control devices, as needed, to
prevent undesirable system failure modes.
Note:
Use of the actuator’s top and bottom center
mounting slots with the isolation grommets is
the preferred mounting arrangement when
using shafts 10 mm (0.472 inch) square or
7/16 inch (11 mm) round or larger. 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).
When using the blade pin extension and/or the
universal mounting bracket, follow installation
procedures packaged with the product.
