Mounting and
Installation Notes
Mount the immersion stem so that the air flows through the opening at the sensor head.
The immersion stem is pre-mounted and wired to the transducer on delivery. The
sensor pipes and the end with the direction arrow are prearranged on the connecting
cable; fit them together (use the direction-oriented snap-on connections). If the
extension pipe is not required, remove it from the cable. The connecting flange is not
attached on delivery.
The sensor is supplied with Installation Instructions.
