NOTE: Refer to Figure 5 and Figure 6 for packing of the 769-605-INT Fluorine/Chlorine Trap Assembly.

1. Set the 769-605-INT Fluorine/Chlorine Trap Assembly next to the furnace (Figure 1 or Figure 2). 2. Turn OFF the oxygen supply. 3. Disconnect the tubing from the measure flow fitting on the cleaning head (Figure 1 or Figure 2). 4. Remove the shipping plugs from the inlet and outlet of 769-605-INT Fluorine/Chlorine Trap

Assembly (Figure 5 or Figure 6). 5. Connect a section of 537-103 Tubing between the OUTLET (top) port of the 769-605-INT

Fluorine/Chlorine Trap Assembly and the measure flow fitting on the cleaning head (Figure 1 or Figure 2).

6. Connect a section of 537-103 Tubing between the INLET (bottom) port of the 769-605-INT Fluorine/Chlorine Trap Assembly and the tubing/fitting disconnected from the measure flow fitting in step 3 (Figure 1 or Figure 2).

NOTE: Keep tubing length to a minimum. Excessive length necessitates increased combustion time.

NOTE: Refer to Figure 5 and Figure 6 for packing of the 769-605-INT Fluorine/Chlorine Trap Assembly.

1. Position the 769-605-INT Fluorine/Chlorine Trap Assembly to the right of the unit (Figure 3 or Figure 4).

2. Turn OFF the oxygen supply. 3. Disconnect and remove the stainless steel delivery tube between from autocleaner and furnace gas

scrubber. 4. Remove the shipping plugs from the 769-605-INT Fluorine/Chlorine Trap Assembly inlet and outlet

(Figure 5 and Figure 6). 5. Connect a section of 537-103 Tubing between the OUTLET (top) port of the 769-605-INT

Fluorine/Chlorine Trap Assembly and the fitting on the autocleaner (Figure 3 or Figure 4). 6. Connect another section of 537-103 Tubing between the INLET (bottom) port of the 769-605-INT

Fluorine/Chlorine Trap Assembly and the top of the furnace gas scrubber tube (Figure 3 or Figure 4).

NOTES: • Keep tubing length to a minimum. Excessive length necessitates increased combustion time. • Fluorides decrease the life of the autocleaner O-rings. It will be necessary to disassemble the

cleaner daily and change or re-grease the internal O-rings of the cleaner.

OPERATION

1. Turn ON the oxygen supply and set it for specified flows and pressures according to the appropriate instruction manual.

2. Set the combustion time on the C-200, C-230, CS-200, CS-230, S-200 and S-230 for 70 seconds. Set the combustion time on the C-600, CS-600 and S-600 for 50 seconds (nominal). This is to compensate for increases volume in the measure line.

3. After the system has purged for a minimum of 5 minutes, perform calibration according to the appropriate instruction manual.

MAINTENANCE

CHLORINE TRAP NOTE: Replace the 769-605-INT Fluorine/Chlorine Trap Assembly reagent tube before it becomes

completely depleted. The reagent changes color from white to yellow to orange to orange/brown. The reagent must be changed before it becomes to brown in color. Also, the reagent tube must be repacked if the 769-608-HAZ Metal at the outlet loses its luster and becomes dull in appearance.

1. Repack the tube as follows (Figure 4).

a. Discard depleted reagent and all material in the trap tube except the screens and glass tube. b. Wash and dry the glass tube. c. Place a fresh 601-081 Glass Wool plug, approximately 1½-inches (38 mm), at the bottom of the

glass tube. d. Add a layer of 769-608-HAZ Absorbent Metal approximately 1-inch (25 mm or 32 grams ±2

grams) deep. Tap the sides of the tube to allow settling. e. Cover the metal with ½-inch (13 mm) of glass wool. f. Add enough 769-610 Absorbing Reagent to fill all but the last 1½-inches (38 mm) of the wider

part of the tube (approximately 70 grams). g. Place ½-inch (13 mm) of glass wool over the reagent. h. Add enough 769-608-HAZ Absorbent Metal to make a layer 1-inch (25 mm) deep. i. Fill the remainder of the tube with glass wool and place 769-193 Screens at both ends.

NOTE: Insert the filled tube immediately in the stand or plug both ends to avoid contamination by

moisture from the atmosphere. Close all reagent bottles tightly.

REVISION DATE: ORIGINAL DATE: 01-14-08 FLUORINE TRAP NOTE: Replace the 769-605-INT Fluorine/Chlorine Trap Assembly reagent tube before it becomes

completely depleted. The reagent changes color from orange to a darker orange/brown. The reagent must be changed before it becomes to brown in color.

1. Repack the tube as follows (Figure 4).

a. Discard depleted reagent and all material in the trap tube except the screens and glass tube. b. Wash and dry the glass tube. c. Place a fresh 601-081 Glass Wool plug, approximately 1½-inches (38 mm), at the bottom of the

glass tube. d. Add a 502-351 Halogen Scrubber to fill all but the last 1½-inches (38 mm) of the wider part of the

tube. Tap the sides of the tube to allow settling. e. Fill the remainder of the tube with glass wool and place 769-193 Screens at both ends.

NOTE: Insert the filled tube immediately in the stand or plug both ends to avoid contamination by

moisture from the atmosphere. Close all reagent bottles tightly.
