6.7 Replacing The Hydrocarbon (HC) Scrubber

1. Turn off power and unplug the M701H power cord.

2. Disconnect the HC scrubber power at the Controller.

3. Unplug the thermocouple from the control board.

4. Remove the heat shield from the HC scrubber.

5. Disconnect the pneumatic connections at the CHARCOAL SCRUBBER INLET AND

AT THE REAR END OF THE COPPER COOLING COIL, using 1/2 and 9/16

wrenches.

CAUTION

WAIT FOR THE SCRUBBER TO COOL. THE SCRUBBER CASING

AND THE COPPER COOLING COIL WILL BE VERY HOT.

5. Remove the four screws holding the scrubber, under the chassis.

6. Lift out the scrubber.

7. Install a new Teledyne API-supplied scrubber (these are purged at the factory).

8. Screw it down.

9. Attach and tighten the pneumatic connections.

CAUTION

ENSURE THAT THE COPPER COOLING COIL IS NOT TOUCHING

ANY WIRE OR CABLE.

10. Plug the scrubber into the control board.

CAUTION

BE SURE THAT YOU USE A TELEDYNE API-SUPPLIED, PURGED

SCRUBBER. OTHERWISE, DOWNSTREAM COMPONENTS MAY BE

DAMAGED. AN UNPURGED HYDROCARBON SCRUBBER

PRODUCES A LOT OF WATER WHEN FIRST TURNED ON.

11. Plug the thermocouple into the control board.

12. Turn on the M701H.

13. Connect a millivolt meter to J12 (labeled “Thermal Couple” in Figure 5-3) on the

temperature controller.
