other explosive vapors.
CAUTION
Electrical Shock or Equipment Damage Hazard.
Can shock individuals or short equipment
circuitry.
Disconnect all power supplies before installation.
Actuators with auxiliary switches can have more than
one disconnect.
CAUTION
Actuator Damage Hazard.
Deteriorating vapors and acid fumes can damage
the actuator metal parts.
Install actuator in areas free of acid fumes and
deteriorating vapors.
Location
Choose a location for the actuator that allows enough
clearance for mounting accessories and for servicing.
Mounting
These actuators are designed to open a damper or valve by
driving the shaft in either the clockwise (cw) or
counterclockwise (ccw) direction. The actuator has a
mounting tab on the bottom that secures it to a damper box or
valve linkage. When mounted correctly, this tab allows the
actuator to float without rotating relative to the shaft. The tab is
sized for 1/4 in. self-tapping sheet metal screws (not
included).
CAUTION
Equipment Damage Hazard.
Tightly securing mounting tab to damper housing
can damage actuator.
Once mounted, the actuator must be allowed to float;
do not fully tighten the screw.
These actuators are shipped in the fully clockwise 90° position
as viewed from the end of the damper shaft.
CAUTION
Equipment Damage Hazard.
Mounting actuator unevenly with damper housing
can damage actuator.
Mount actuator flush with damper housing or add
spacer between mounting tab and damper box
housing (see Fig. 2).
