9. Install the replacement adsorber.  Remove the two dust caps from the replacement 

adsorber.    Put the adsorber into the compressor so as to place it at the mounting tab 
on the base of the compressor.  Secure the adsorber with the mounting bolt 
temporally.   

 

10. Connect self-sealing coupling to the adsorber with the two spanners.  Tighten the 

coupling referring to Figure 7-5.  Recommended tightening torque is 20N

･

m.  

Connect the coupling quickly to minimize helium leakage. 

 

11. Put the rear panel back on the compressor to align the helium connector of the 

adsorber with the hole of the rear panel and then remove the rear panel again.    Fix 
the adsorber mounting bolt firmly this time.
