During cover removal and conduit entry removal, ensure that surfaces are
free from scratches or scrapes.
Actuator installation and maintenance must be performed by trained
personnel.
Cover Removal
Please gently remove the cover, but first remove the conduit entry metal plugs to
relieve the pressure inside the actuator and in order to avoid a vacuum by lifting the
cover. It will ease the top cover removal. DO NOT attempt to remove the top cover
with a screwdriver as it will damage the closing surfaces.
Cover Installation
Please ensure that the O-ring seal is in good condition prior to cover
installation. Slowly re-install the cover while being careful not to pinch the
O-ring seal.
The explosion-proof enclosures are marked with a QA-code on both of the
connection flanges. Please verify that QA-code inside the cover is identical
to the one on the connection flanges-during installation. Covers of these
actuators are not interchangeable!
Please follow below table to tighten the top cover screws:
