WARNING
!
Risk of personal injury when the actuator vents.
The actuator is operated with air. As a result, air is vented during operation.
Î Install the control valve in such a way that vent openings are not located at eye level
and the actuator does not vent at eye level in the work position
Î Use suitable silencers and vent plugs.
Î Wear eye and hearing protection when working near the actuator.
Risk of personal injury due to preloaded springs.
Actuators with preloaded springs are under tension. These actuators can be identified
by several longer bolts with nuts protruding from the bottom diaphragm case. These
bolts allow the spring compression to be relieved evenly on disassembling the actuator.
Actuators with considerably preloaded springs are also labeled correspondingly (see
section 1.4).
Î Before starting any work on the actuator, relieve the compression from the preload-
ed springs. See 'Relieving the spring compression in the actuator' in the 'Removal'
section.
Exposure to hazardous substances poses a serious risk to health.
Certain lubricants and cleaning agents are classified as hazardous substances. These
substances have a special label and a material safety data sheet (MSDS) issued by the
manufacturer.
Î Make sure that an MSDS is available for any hazardous substance used. If neces-
sary, contact the manufacturer to obtain an MSDS.
Î Inform yourself about the hazardous substances and their correct handling.
Risk of personal injury through incorrect operation, use or installation as a result of
information on the actuator being illegible.
Over time, markings, labels and nameplates on the actuator may become covered with
dirt or become illegible in some other way. As a result, hazards may go unnoticed and
the necessary instructions not followed. There is a risk of personal injury.
Î Keep all relevant markings and inscriptions on the device in a constantly legible
state.
Î Immediately renew damaged, missing or incorrect nameplates or labels.
