6.1 PCA 2 Disassembly

The following procedure describes how to disassemble the analyzer, while Figures 6-1 thru 6-4 illustrate how the analyzer is put together.

Tools Required:

Medium Phillips Screwdriver Procedure:

1.Unplug all thermocouples from

bottom­ of analyzer.

2.Remove battery cover and then remove batteries.

TIP: In Step 3, if the sensors are not being replaced, leave the tubing connected to each sensor’s gas cap, being careful not to put unneces- sary strain on the tubing during the disassembly process.

Rear Case Screws (typical 4 places)

Release and then remove battery cover by pushing latch up

3. Pull off sensor retainer; and

then unplug all sensors.

 

 

 

4.Lay analyzer face down on a padded work surface; and then using a medium Phillips screwdriver, remove the unit’s four rear-case screws.

5.Lift rear case from analyzer and set aside.

6.Unplug electrical connectors J8, J9, and J14 from printed circuit board.

CAUTION: In Step 7, note that there is tubing connected between the bottom hose-connector plate and the pressure sensor on the printed circuit board. Do not put unnecessary strain on this tubing during the disassembly process.

7.Carefully lift battery-and-pump chassis, along with the bottom hose- connector plate, from analyzer.

8.Lift printed circuit board from analyzer.
