• G 3 or 3 NPT connection: G 3 or 3 NPT connection: G 3 or 3 NPT connection: G 3 or 3 NPT connection: 65 mm open-end wrench (not supplied)
• 3 mm Allen wrench (not supplied)
• If the device does not have an antenna extension, remove the three locking screws from the
top of the antenna with a 3 mm Allen wrench. If the device has one or more antenna
extensions, remove the locking screw from the top antenna extension and remove the
antenna and the antenna extensions from the part below the flange.
• Remove the antenna from the part below the flange (if there are no antenna extensions).
i The antenna is not attached to the device. Make sure that the O-ring stays in the groove on
the process connection.
