Use the following procedure to change the adsorber every three years.
1. Set the System Circuit Breaker, on the rear of the 9600
Compressor, to the OFF position.
2. Remove the 4 screws which secure the rear panel to the
Compressor and remove the rear panel.
NOTE: Use two wrenches in Step 3 to prevent loosening the body of the
coupling.
3. Using a 1-3/16 in. wrench, and a 1-1/8 in. wrench, as shown in
Figure 5-1, disconnect the two self sealing coupling connectors
quickly to minimize helium leakage.
This 1 1/8 (or 1) in. wrench
holds the coupling in a sta-
tionary position.
