Routine Maintenance
8-8
WARNING
Failure to replace the filter bowl in the locked position could result in catastrophic
failure and personal injury.
8.9 Cleaning
8.9.1 Helium compressor and dewar
The helium compressor and dewar 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.
8.9.2 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.
8.10 Replaceable fuses
8.10.1 Helium compressor
See the Fuse Specifications table in Section 5 for the ratings and characteristics of all
replaceable fuses in the helium compressor.
Qualified service personnel only should replace the fuses.
