Damage to the diffusion element may be- come apparent during calibration. Compare probe response with previous response. A broken diffusion element will cause a slower response to calibration gas.

Hex wrenches needed to remove setscrews and socket head screws in the following pro- cedure are available as part of a special tool kit, Table A-3.

Wear heat resistant gloves and cloth- ing to remove probe from stack. Nor- mal operating temperatures of diffusor and vee deflector are approximately 600° to 800°F (300° to 425°C). They can cause severe burns.

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

It is not necessary to remove the cell unless it is certain that replacement is necessary. Cell cannot be removed for inspection without damaging it. Refer to paragraph A-11,Cell Replacement.

b. Replacement Procedure

3.On systems equipped with abrasive shield, remove dual dust seal gaskets.

4.Use spanner wrenches from special tools kit, Table A-3,to turn hub free from retainer.

5.Put hub in vise. Break out old diffusion element with chisel along cement line and 3/8 inch (9.5 mm) pin punch through cement port.

6.Break out remaining diffusion element by tapping lightly around hub with hammer. Clean grooves with pointed tool if necessary.

7.Replace diffusion element, using re- placement kit listed in Table A-3.This consists of a diffusion element, ce- ment, setscrews, anti-seize compound and instructions.

8.Test fit replacement element to be sure seat is clean.

Do not get cement on diffusion ele- ment except where it touches the hub. Any cement on ceramic element blocks airflow through element. Wip- ing wet cement off of ceramic only forces cement into pores.

1.Shut off power to electronics. Discon- nect cable conductors and remove ca- ble, Figure A-16.Shut off and disconnect reference air and calibration gas supplies from probe junction box. Wearing heat resistant gloves and clothing, carefully remove probe as- sembly from stack and allow to cool to room temperature. Do not attempt to work on unit until it has cooled to a comfortable working temperature.

2.Loosen setscrews, Figure A-17,using hex wrench from special tools kit, Table A-3,and remove vee deflector. Inspect setscrews. If damaged, replace with M-6 x 6 stainless setscrews coated with anti-seize compound.

9.Thoroughly mix cement and insert tip of squeeze bottle into cement port. Tilt bottle and squeeze while simultane- ously turning diffusion element into seat. Do not get any cement on upper part of diffusion element. Ensure com- plete penetration of cement around three grooves in hub. Cement should extrude from opposite hole. Wipe ex- cess material back into holes and wipe top fillet of cement to form a uniform fillet. (A Q-Tip is useful for this.) Clean any excess cement from hub with water.

10.Allow filter to dry at room temperature overnight or 1 to 2 hours at 200°F (93°C).
