Maintenance
We recommend installing a complete, new displacer piston after 9,000 hours
of operation.
This job can only be performed by Oerlikon Leybold Vacuum Service or
appropriately trained service personnel.
Oerlikon Leybold Vacuum offers practical seminars in which simple main-
tenance, troubleshooting of cold heads and other cryogenic components are
covered by qualified instructors. Further details are available upon request.
Improper maintenance negatively affects safety, service life and operability
and also voids your warranty.
Following repairs to the electrical circuits the cold head shall not be
returned to service before making an electrical safety test. For this reason
work such as this may be carried out only by trained and qualified service
personnel.
