of direct contact with corrosive gas, chemical products, salt water, water or steam.
•
If possible, do not install the device:
o
in closed and small spaces
o
exposed to direct sunlight (if necessary provide a shield)
o
near heat sources or in areas subject to sudden changes in temperature
o
near power on parts with no proper insulation

Maintenance
•
Check all conditions to prevent the inadvertent release of parts, and disconnect the power
supply to enable the discharge of residual pressure from the system before performing work.
•
Discharge all pressure from the system and the actuator itself.
