WARNING FOR ATEX:
If not observed, user incurs a high risk of severe dam-
age to actuator and/or fatal injury to personnel.
CAUTION:
Don’t exceed the permitted values!
Exceeding the permitted pressure value marked on the
actuator may cause damage and lead to uncontrolled
pressure release in the worst case. Damage to the equip-
ment and personal injury may result.
CAUTION:
Don’t dismantle a pressurized actuator!
Dismantling a pressurized actuator leads to uncontrolled
pressure release. Shut off the supply pressure and release
pressure from the cylinder before dismantling the actua-
tor. Otherwise, personal injury and damage to equipment
may result.
CAUTION:
Follow the instructions given on the actuator warning
plates!
CAUTION:
Before opening the cylinder fastening screws (11),
release spring tension directed on actuator warning
plate and in these instructions!
CAUTION:
Don’t dismantle the spring module!
Do not remove the spring module while the spring is com-
pressed or under pressure.
CAUTION:
Take the weight of the actuator or valve combination
into account when handling it!
Lifting lugs on the actuator are meant only for lifting
actuator and not complete valve assembly.
Do not lift the valve combination from the actuator, posi-
tioner, limit switch or their piping. Lift the actuator as
directed in Section 2, lifting ropes for a valve combination
should be fastened around it. The weights are shown in
Section 9. Dropping may result in personal injury or dam-
age to the equipment.
WARNING FOR ATEX:
While lifting actuator housing should not
impact on the other light or rusty metal .
CAUTION:
Potential electrostatic charging hazard, do not rub
surface with dry cloth.
WARNING FOR ATEX:
Inspect for paint damaged, to ensure contin-
ued corrosion protection.
Actuator speed should not faster than speci-
fied in the following chart.
