code then the air detection sensor will require replacement.
b) Power down the instrument and remove the sample hose from the instrument sample inlet port.
c) Turn the instrument onto its face and remove the eight phillips head screws from the rear countersunk holes.
d) Carefully remove the instrument case front to expose the internal components.
e) Carefully lift the control circuit board and disconnect the air detection sensor harness from the circuit by pulling
straight out of the circuit board connector.
f) Lift the air detection sensor housing straight up from the instrument off of the support pins and remove the
sensor by unthreading. Discard the spent sensor.
g) Obtain a replacement air detection sensor, part number 1-16-1013-00-0, and install it into the housing by
threading to hand-tight.
h) Replace the housing into the instrument by seating the housing through holes over the two case pins.
i) Route the sensor harness to the circuit board and plug it into the sensor harness header of the circuit by pressing
straight in. The harness is keyed and will only fit securely in one direction.
