TROUBLE ShOOTING
6.1 GENERAL
Correct service and maintenance is essential for the long term serviceability of
precision engineered products such as the Cryotome. We strongly recommend that
a Thermo Service Contract is used to ensure future reliability, and consistency of
performance.
Cryotome has self test routines built in so that fault codes
(f:(Number)) show in the
displays if malfunctions occur. No operator response is involved following a fault code
other than to contact your Thermo Engineer for service.
Table 1 lists basic instrument function problems and solutions.
Table 2 lists other problems and their causes that are not shown in the displays.
Table 3 lists alarm signals, their causes, and the remedial action to be taken.
If a fault indication continues or recurs, remove the samples from the refrigerated
chamber and store them in a suitable refrigerated container and contact your Thermo
Service Representative.
