c. Install the replacement adsorber following the steps for
compressor adsorber removal in reverse order. Use the hard-
ware saved in step 5 above.
2. Connect the adsorber to the compressor internal piping. Refer to
Figure 4-1.
a. Check the self-sealing connector flat rubber gasket to make
sure that it is clean and properly positioned.
Make sure to hold fast on the left coupling nut while tightening the
right coupling nut, as shown in Figure 4-1.

nection using the two wrenches until the fittings "bottom".
Refer to Figure 4-1, for proper coupling of the self-sealing
connection
3. Replace the cover and the front and rear grilles and secure them
4. Ensure that the pressure gauge reads 245-250 psig (1690-1725
kPa). If additional gas pressure is required, follow the instructions
in, Adding Helium Gas.
5. Reconnect the return and supply flex lines to the compressor.
6. Connect the compressor input power cable to the electrical power
source.
It is advisable to keep on hand the unscheduled maintenance equipment
