Installation 

Install the AVC Balancer 

If a passive balancer is attached to the cryocooler, remove the bolt from the middle of the passive balancer and 
remove the passive balancer from the cryocooler. Now install the AVC balancer as follows: 

1.  Unscrew and remove the hex standoff from the balancer (figure 2). 

2.  Screw the hex standoff onto the cryocooler end plate. 

3.  Place the balancer onto the hex standoff, insert the long bolt through the middle of the balancer and into the 

hex standoff, and tighten the bolt. (Figure 3 shows the AVC balancer attached to a cryocooler.)
