1) Inspect the reliquefier for any damage to the liquid return line or main assembly.

6.2 Helium Reliquefier Installation into your cryostat
NOTE
A liquid return line protector is attached to the Helium Re-liquefier assembly which is used
for shipping, pre-installation, and storage purposes. It is wrapped in black and yellow
caution tape for identification. Do not remove this until the Re-liquefier is ready to be
lowered into the application. Do not is dispose of this part.
1. The Helium Re-liquefier must be mounted on an adjustable stand. If you have
purchased the stand from Cryomech, Inc., please follow the installation
instruction of the stand. If you choose to build your own stand, please use the 8
screw holes with 5/16-18 thread on the bottom of the main assembly for
mounting (see attached drawing in Appendix A). The stand should be sufficient
to hold the 75 lbs (34 kg), rigidly, with the liquid return line, perpendicular to the
floor of the room.
2. Before the liquid helium return line is lowered into the fill port, carefully unscrew
and remove the liquid return line protector as see in Figure 6-2. Save the liquid
return line protector incase the re-liquefier is removed from the application.
Extreme caution should be used when lowering or raising the liquid helium return
line and precautions should be taken to ensure that the liquid helium return line
is not bent as it enters into and resides in the fill port.
