General
The spring return actuator is shipped in spring return position (spring unloaded).
Standard actuators will be supplied with a clockwise spring return action for closing
the valve in case power outage occurs. However actuators can optionally be supplied
with a counter-clockwise spring return action for opening the valve.
DO NOT
install in ambient temperatures that exceed 70°C (158 °F).
DO NOT
, under any circumstances, remove the cover of the actuator while in a
hazardous location when the power is still live inside the actuator. This could cause
ignition of a hazardous atmosphere.
DO NOT
, under any circumstances, use an explosion-proof electric actuator in a
hazardous location that does not meet the specification which the actuator was
designed for.
Mount, test, and calibrate actuators in a non-hazardous location.
When removing the actuator, care must be taken not to scratch, scar or deform the
flame path of the cover or base of the actuator. This will negate the protection rating
of the enclosure in a hazardous location.
The explosion proof electric actuator is shipped with mating surfaces of the cover
