RC-5B PLUS In~roduction & Description
Section 1: I~TRODUCTIO~ & DESCRIPTIO~
This manual is a service guide for the SORVALL~~~ RC-5B PLUS ~~~~~~~~~~ Refrigerated Centrifuge. It
contains descriptive information, mechanical and electrical theories of operation, maintenance procedures,
calibrations, and an illustrated parts list for ordering replacements.

To avoid personal injury, all
replacement and calibration proce¬
dures should be performed by quali¬
fied service personnel.
1-1. Intended Use
This manual is for qualified service personnel who are familiar with
electronics and factory methods for performing repairs, adjust¬
ments, and calibrations. It provides a fault isolation method that
isolates and identifies the cause of a problem within the centrifuge,
a parts list, and information for ordering replacement parts needed
for the repair of parts or systems within the centrifuge.
Warnings, Cautions, and Notes are used throughout this manual to
emphasize important and critical instructions. Service personnel
are expected to be familiar with their meaning (see page ~~~ and to
read them before servicing the centrifuge.
1-2. Centrifuge Description
The RC-5B PLUS is a high-speed (to 21 000 ~~~~~ floor-model
centrifuge used to separate substances of different densities at
controlled temperatures. Its function is to increase the effects of
gravity by centrifugal force to separate substances of different size
or densities at controlled temperatures.
The centrifuge has a fan-cooled motor that is balanced and enclosed
in an air-cooled silencer to ensure smooth, quiet operation over its
full speed range and to promote long life for the brushes and
bearings. The durable motor brushes have increased life and the
gyro-action self-centering drive spindle allows you to balance the
centrifuge tubes by "eye" rather than by weighing them.
The refrigeration system is a low-temperature, hermetically-sealed
unit consisting of a compressor, condenser, evaporator/rotor
chamber and interconnecting tubing. It is charged with SUVA~~~refrigerant,
one of ~~~~~~~~ ~~~~~~~~~~~~~~~ coolants. During
operation, the cooling system will maintain rotor compartment
temperature within 1°C ~~~~~~~~~~~
Run parameters are selected ~~ setting the dials on the front control
panel. Actual run conditions are continuously displayed during
operation by easy-to-read analog displays.
