INSIGHT

7. Strip

/4 inch of insulation from each of the probe’s thermocouple

connector wires.

IMPORTANT: In Step 8, the thermocouple wires must first be twisted

together and then crimped.

8. Twist both red thermocouple wires together; insert them into the

supplied wire-splice connector; and then crimp the connector using

a pair of pliers. Repeat this step for the yellow thermocouple wires.

9. Reassemble the probe handle, being careful not to pinch the ther-

mocouple wires between the handle pieces. In addition, ensure that

the end of the thermocouple is in front of the rib molded into the

bottom handle piece; otherwise, the handle pieces will not fit tightly

together.

6.6 Gas Pump Replacement

Parts & Tools Required:

• Replacement pump (P/N 24-3049)

• Medium phillips screwdriver

Procedure:

1. Gain access to the gas pump by removing the rear case. Refer to Sec-

tion 6.1.

2. Disconnect J9 (pump) and J11 (Battery) connectors.

3. Lift the circuit board out of the unit.

4. Remove the screw that secures the pump to the board in order to

separate the pump from the board.

5. Remove tubing from pump.

6. Install new pump by reversing this procedure.

6.7 Cleaning the Probe

The probe tube and gas-sample hose will become dirty under normal use.

Note that the water trap’s filter element should prevent soot from reaching

the analyzer’s internal components. If the probe is not kept clean, it could

become clogged and restrict the flow of gas into the analyzer, resulting in

incorrect combustion test readings and calculations.
