Service Instructions
MAINTENANCE
Beginning after the first 300 hours of use, and periodically thereafter, a qualified electronics technician
should inspect the centrifuge.
Cleaning & Lubrication The rotor, rotor chamber and centrifuge casing must be kept
clean. Using a cloth damp with water or mild detergent, the
casing and chamber should be wiped clean and kept in "like-
new" condition. Clean all spills immediately, removing the
rotor for best results. No routine lubrication is necessary.
Disconnect from power source before any cleaning proce-
dure. No flammables or solvents are to be used, especially
in the presence of electrical power or in a recently used (still
warm) centrifuge.
Removing the rotor 1) Using an adjustable or 1/4 inch wrench, loosen the rotor
screw and remove the rotor retaining screw/washer
assembly by turning it counter-clockwise.
2) Lift the rotor straight up and out of the chamber.
3) To reinstall the rotor, reverse the above procedure. Be
sure the cross pin on shaft lines up with slot on under-
side of rotor.
Maintaining the rotor The rotor must be checked periodically (every 12 months or
more often if required) for signs of wear, damage or misuse.
Corrosive materials must be promptly cleaned and thor-
oughly removed. For best results, disassemble the rotor by
removing the 3 screws at the bottom and pulling the upper
and lower components apart. The rotor must be reas-
sembled in the same orientation. The rotor can be auto-
claved or wiped with radioactive decontaminant only when
disassembled. It should not be soaked in decontaminant.
When reassembling the rotor, be sure to return the upper
and lower sections to their original orientation. Misalignment
could result in a moderate imbalance and increased vibra-
tion during high and low speed operation. The three screws
must be tightened firmly.
Any cracks, deep scratches, stress marks or other damage
to the rotor should be reported immediately. Any rotor
exhibiting any of the above indicators must be removed from
service immediately. Failure to do so may result in injury.
