Adsorber Replacement

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 Compres- sor 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 Fig- ure 5-1, disconnect the two self sealing coupling connectors quickly to minimize helium leakage.

4.Using a 7/16 in. (11mm) wrench, remove the adsorber mounting bolt as shown in Figure 5-2.

5.Move the adsorber from under the mounting tabs in the base as shown in Figure 5-2 and remove the adsorber from the Compressor.

6.Install the replacement adsorber under the mounting tabs and secure it into place with the bolt removed during Step 4.

7.Using two wrenches as shown in Figure 5-1, connect the two self sealing couplings quickly to minimize helium leakage.
