Replacing the Sensor ‒ Figures 29 and 30
NOTE: Replace the sensor in a clean, nonhazardous
environment. Make sure a new hydrophobic filter
and charcoal filter are available before changing the
sensor.
6.2.1
Make sure the monitor is turned OFF.
6.2.2
Use a small Phillips screwdriver to unscrew the
sensor-retainer’s screw.
6.2.3
Remove the sensor retainer.
6.2.4
Remove the sensor gasket and filters. The filters
may fall out. The sensor will be exposed.
6.2.5
Remove the old sensor by pulling it straight up
from the sensor socket.
NOTE: The bottom of the
sensor is slotted and can only be inserted in the
socket one way, as shown in Figure 29. Before
removing the sensor, note the orientation of the old
sensor alignment points, as shown in Figure 30. The
new sensor will insert with the same orientation.

NOTICE
Do not force the sensor into the socket; when
correctly oriented, the sensor easily fits into the
socket. Forcing it could damage the sensor or
the socket.
6.2.6
Carefully insert the replacement sensor. Make
sure the sensor face with the colored ring is facing up,
and that the sensor’s orientation slots are aligned
correctly with the tabs within the socket, as shown in
Figure 30. Do not force the sensor into its socket; if the
sensor is correctly aligned, it easily sets into the socket.
