8.7 Cleaning
8.7.1 Compressor package and cold head
The compressor package and cold head require no cleaning other than wiping the
outside of each if it becomes dusty or dirty.
CAUTION
Never wet either part of the system. Water getting into the system will void the
warranty.
8.7.2 Aeroquip couplings
WARNING
Never remove an Aeroquip coupling from the helium flex lines, cold head or
compressor without first relieving the helium charge. The pressure in any of the
components can blow off the coupling with sufficient force to cause injury.
If operated in a clean environment, the only parts of the cryorefrigerator system that are
likely to require cleaning are the Aeroquip couplings. The mating surfaces of the
Aeroquip couplings can get particles on them when the helium flex lines are detached
from the compressor package and/or the cold head.
If an Aeroquip coupling needs cleaning:
Wipe the mating surfaces of the coupling with a dry, lint-free cloth.
After wiping, blow off the coupling with clean, dry compressed air.
Solvents should never be used.
If any grease or oil gets on the Aeroquip coupling, contact Cryomech.
8.8 Manufacturer only parts
The following parts are available only from Cryomech:
Helium flex lines
The helium flex lines must be handled with care. If they become damaged and need to be
replaced, new ones must be obtained from Cryomech and installed using the directions in
the installation section of this manual.
Adsorber
The adsorber needs to be replaced after every 20,000 hours of use. See Section 8.4 for
instructions on replacing the adsorber.
Cold head
The cold head contains no user-serviceable parts and must be serviced by Cryomech
authorized technicians. Attempting to disassemble the cold head will void the warranty.
See Section 8.3.
