18 . Hold the electrode stack between the thumb and forefinger of one hand
and place the window end of the lamp inside the O-ring seal in the
electrode stack with the other hand as shown below.

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
