e.Slide assembled probe junction box and in- ner probe assembly into probe tube. To align calibration gas tube with correspond- ing hole in backplate (A, B, Figure A-1),in- sert aligning tool (included in probe disassembly kit, P/N 3535B42G01) through hole in backplate and into calibration gas tube, while sliding the heater strut into the probe tube. Secure with screws. Reinstall hoses and probe junction box cover.

f.Power up system. Monitor thermocouple output. It should stabilize at set point ±0.2 mV. Recalibrate probe per Instruction Bulle- tin applicable to your electronics package.

LINES FOR HIGH TEMPERATURE - CORROSIVE ENVIRONMENT OPERATION

A high temperature, corrosive environment kit is available when the probe is exposed to these types of operating conditions. The kit includes stainless steel tubing and teflon fittings for in- side the probe junction box. The kit part number is 4843B93G01.

a. Installation Procedure

Use heat resistant gloves and clothing when removing probe junc- tion box and inner probe assembly. Do not attempt to work on these com- ponents until they have cooled to room temperature. Probe components can be as hot as 800°F (427°C). This can cause severe burns.

Disconnect and lock out power before working on any electrical components. There is voltage up to 115 Vac.

1.Disconnect and lock out power to digi- tal electronics. Using heat resistant gloves and clothing, remove probe cover. Squeezing tabs on hose clamps, remove hoses from probe junction box (Figure A-21).
