Scheduled Maintenance

Removing the Compressor Adsorber

P/N 8040353
Always disconnect the compressor from all sources of electrical power
before performing any maintenance procedures.
The only scheduled maintenance required on the 8200 Compressor is
replacement of the compressor adsorber (P/N 8080255K001) every 12
months.
1. Shut down the compressor.
2. Disconnect the compressor input power cable from its electrical
power source.
3. Disconnect the flex lines from the gas-return and gas-supply con-
nectors at the rear of the compressor.
4. Remove the screws holding the compressor rear grille, rear panel,
front panel and cover (Figure 1-2). Front and rear panels remain in
place.
5. Use the two wrenches (supplied) to avoid loosening the body of the
coupling from its adapter.
6. Unscrew the two self-sealing coupling halves quickly to minimize
gas leakage as shown in Figure 4-1.
7. Disconnect the adsorber-inlet self-sealing coupling as shown in
Figure 4-1.
8. Remove the bolts, nuts, and washers that secure the adsorber to the
base of the compressor. Save all nuts, bolts, and washers for install-
ing the replacement adsorber.
9. Carefully lift the adsorber inward until the outlet self-sealing cou-
pling clears the rear panel and remove the adsorber as shown in
Figure 4-2.
10. Remove the adsorber from the compressor as shown in Figure 4-2.
