When Installing this Product...
1.
Read these instructions carefully. Failure to follow
them could damage the product or cause a hazardous
condition.
2.
Check the ratings given in the instructions and on the
product to make sure the product is suitable for your
application.

technician.
4.
After installation is complete, check out product
operation as provided in these instructions.
IMPORTANT
All wiring must agree with applicable codes,

WARNING
Electrical Power Hazard.
Line voltage can cause death or serious injury
and short equipment circuitry.
Disconnect power supply before installation.
CAUTION
Electrical Shock or Equipment Damage Hazard.
Low voltage can shock individuals or short
equipment circuitry.
Disconnect power supply before installation.
Location and Mounting
The actuators are designed to open a damper by driving the
damper shaft in either clockwise
or counterclockwise
direction. The actuator housing has two slots on the
bottom that, with a 205649 Mounting Bracket, secure it flush to
a damper box (see Fig. 2). When mounted correctly, these
slots allow the actuator to
float
without rotating relative to the
damper shaft.
CAUTION
Equipment Damage Hazard.
Tightly securing actuator to damper housing can
damage actuator.
Mount actuator to allow it to float along its vertical axis.

Preparation
Before mounting the actuator onto the damper shaft,
determine the:
— Damper/valve opening direction for correct spring
return rotation. The actuator can be mounted to provide
clockwise or counterclockwise spring return.
— Damper shaft size (see Specifications section).

ENSURE THAT MOUNTING ASSEMBLY PREVENTS ACTUATOR
ROTATION AND ALLOWS ACTUATOR TO FLOAT ALONG
INDICATED AXIS. WHEN TOO TIGHT, THE RESULTING BINDING
CAN DAMAGE THE ACTUATOR OR REDUCE TORQUE OUTPUT.
ACCESSORY MOUNTING BRACKET IS NOT SUPPLIED WITH
THE ACTUATOR.
