Maintenance	3000ZA-3X

2.Open the front panel door by pressing the release button on the top right corner of the door all the way in with a narrow gauge tool.

3.Remove the eight screws that hold the cover of the sensor block. As you remove the cover make sure the O-rings stay in place. If they drop, place them back carefully in the groove found on the cell block, not on the cover. See Figure 5.1.

4.You can remove the sensor that you want to replace with your fingers or using small pliers. Just pull the sensor straight out.

CAUTION: SENSORS MIGHT BE HOT! AFTER REMOVING POWER. LET THE SENSORS COOL FOR A FEW MINUTES.

5.Install the new sensors paying attention to relative position in the sensor block. Note orientation of sensor tab aligning with tab location on the silkscreen of the mounting PCB. Sensor is held by friction of the pins sockets. The locations of the Sensors are:

On the left side P/N S1439 (0-200 ppm range ) On the center P/N S1492 (0 – 2 % range )

On the right side P/N S1442 (0 – 95 % range )

CAUTION: MAKE SURE OF THE CORRECT POSITION OF EACH SENSOR. DO NOT PLACE A SENSOR IN THE WRONG SOCKET OR THE ANALYZER WILL FAIL!
