Caution The procedures outlined in this section should be performed only
by qualified service personnel or people trained and certified in
electrical/mechanical repair of laboratory equipment.
With the exception of the chamber air filter, Model SHKE8000/
SHKE8000-ICE and SHKE8000-7/SHKE8000-8CE Orbital Shakers
contain no user-serviceable components. Table 4-1 lists display messages
which may help diagnose abnormal conditions.
If the microprocessor control system senses a fault, malfunction or
abnormal operating condition, alarm messages appear on the liquid crystal
display. These messages are helpful if service or repair assistance should
become necessary. Refer to the table below and to the alarm matrix on the
the last three pages of this section.
