Inspection and Unpacking
4-2
7. Inspect the cold head for any damage, in particular, small dents on the tubes and
any scratches, especially on the mounting surface of the base plate.
8. Retain the cold head box and packing material to use in the future if you need to
store the cold head or ship it to Cryomech, Inc.
4.3.3 Helium flex lines
1. See weights and dimensions of the flex lines in Section 5 to ensure components
can be moved safely.
2. Inspect the helium flex lines for any signs of damage.
4.3.4 Cold head motor cord
Inspect the cord for any signs of damage.
4.3.5 Tool kit
Cryomech, Inc. systems are shipped with a box of tools. The label on the box lists the
contents included inside.
4.3.6 Helium compressor package
1. The helium compressor package should not be tipped more than 5 at any time.
See weights and dimensions of the helium compressor package in Section 5 to
ensure components can be moved safely.
2. Inspect the helium compressor package for any signs of damage such as dents,
scratches or any signs of oil leaks.
3. Check the pressure readings on both pressure gauges. If either gauge reads 5 psig
(0.34 bar) lower than the static pressure listed in Section 5, contact Cryomech, Inc.
4.4 Returning a system to Cryomech, Inc.
1. Contact Cryomech, Inc. for a Return of Material Authorization (RMA) number, and
for additional detailed instructions on how to properly return system components.
2. Repackage the system:
IMPORTANT
Use the original crate and packaging materials to minimize the likelihood of damage during
shipping.
a) Using the original packing material, rewrap the cold head and place in the original
cold head box.
b) Place the helium compressor package on the pallet on top of sufficient vibration
dampening material to prevent the wheels from touching the pallet.
c) Strap the helium compressor package to the pallet, making certain that there is
sufficient insulating material between the helium compressor package and the
straps so the straps will not scrape any paint off the helium compressor package.
d) Use protective wrap to secure the helium flex lines and place them in the container.
3. Include shipping labels on the crate showing which side is up and make clear that
the shipment is fragile.
4. Cryomech, Inc. highly recommends using “tip and tell” indicators. These indicators
are helpful in determining whether your package was handled properly. Replace
used “tip and tell” indicators with new ones (three per crate).
5. When the system has been completely packaged, contact Cryomech, Inc. for
shipping instructions.
