19 . Twisting the lamp slightly during insertion will help to ensure the lamp window is
snug against the stack's front electrode. The lamp should be supported by the O-ring.
20 . Continuing to hold the electrode stack between your forefinger and thumb, carefully
insert the lamp into the lamp cavity in the sensor ensuring that the lamp remains in
position.
21 . Press in the electrode stack firmly to ensure that the stack wing clips are engaged and
the faces of the stack and sensor body are flush.
22 . Carefully line up the PID sensor’s connections with the connections on the bottom of
the socket and slowly insert the sensor in the socket.
23 . Do not attempt to push the sensor in farther once it makes contact with the bottom of
the socket until you are sure that the sensor’s connections are engaged with the
socket’s connections. If you feel that the connections did not engage, slightly rotate
the sensor back and forth without putting pressure on it until you feel the connections
engage.
24 . Push the sensor into the socket until it bottoms out.
25 . Place the sensor gasket and filters back over the sensors ensuring that it seals with
the sensors and the flow fittings. The flow fitting connections need to be facing up
and cannot be skewed sideways. The gasket must be pushed down in the center and
secured under the gasket aligning tabs.
Failure to install the sensor gasket appropriately may result in inaccurate gas
readings.
