This manual is a guide for service of the

SORVALL TC6 Tabletop Centrifuge

Data herein has been verified and validated and is believed adequate for the intended use of the

centrifuge. Because failure to follow the recommendations set forth in this manual could produce

personal injury or property damage, always follow the recommendations set forth herein. Sorvall does

not guarantee results and assumes no obligation for the performance of rotors or other products that are

not used in accordance with the instructions provided. This publication is not a license to operate under,

nor a recommendation to infringe upon, any process patents.

This service manual is intended as a service aid. While the manual is kept current and includes

information regarding significant design changes, specific designs may still vary from centrifuge to

centrifuge.

This service manual is intended for use only by service personnel who have been trained by Du␣Pont.

Due to the high electrical potential in this centrifuge, untrained individuals must not attempt any of the

procedures in this service manual.

WARNINGS, CAUTIONS, and NOTES within the text of this manual are used to emphasize important

and critical instructions:

WARNING

:A Warning informs the operator of a hazard or an unsafe practice that could result in

personal injury, affect the operator's health, or contaminate the environment.

CAUTION:

A Caution informs the operator of an unsafe practice that could result in damage of

equipment.

NOTE:

A Note highlights essential information.

W A R N I N G

When using radioactive, toxic, or pathogenic material, be aware of all characteristics of the material and

the hazards associated with it. In the event that leakage or rotor failure occurs, neither the centrifuge nor the rotor

can protect you from the particles dispersed into the air. To protect yourself, we recommend additional precautions

be taken to prevent exposure to these materials, for example, controlled ventilation or isolation. DO NOT USE

MATERIALS CAPABLE OF PRODUCING FLAMMABLE OR EXPLOSIVE VAPORS.

Introduction and Description

Section 1: INTRODUCTION and␣ DESCRIPTION

This manual is a service guide for the SORVALL® TC6®Tabletop Centrifuge. It contains descriptive

information, repair and replacement procedures, schematics, troubleshooting, calibrations, and an

illustrated parts list for ordering replacement parts.

1-1. Intended Use of Manual

This manual is for qualified service personnel who are familiar with

factory methods for performing repairs, adjustments and calibra-

tions.

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 ii) and to

read them before servicing the centrifuge.

1-2. Service Decontamination

Policy

If a centrifuge or rotor that has been used with radioactive or

pathogenic material requires servicing by Sorvall personnel, either

at the customer’s laboratory or at a Sorvall facility, comply with the

following procedure to ensure the safety of all personnel:

1. Clean the centrifuge or rotor to be serviced of all encrusted

material and decontaminate it prior to servicing by the Sorvall

representative or returning it to the Sorvall facility. There must

be no radioactivity detectable by survey equipment.

The SORVALL®Rotors, Tubes, Bottles, Adapters and Accesso-

ries Catalog contains descriptions of commonly used decon-

tamination methods and a chart showing method compatibility

with various materials. This service manual contains specific

guidance about cleaning and decontamination methods appro-

priate for the centrifuge or rotor it describes (see paragraph 7-1).

Clean and decontaminate your centrifuge or rotor as follows:

For TC6®

tabletop centrifuges:

a. Remove rotor from the rotor chamber.

b. Remove motor cover and wash with appropriate

decontaminant.

c. Decontaminate door, rotor chamber, chamber door seal,

and drive, using an appropriate method.

W A R N I N G

Because of the character-

istics of the samples likely to be pro-

cessed in this centrifuge, biological

or radioactive contamination may oc-

cur. Always be aware of this possibil-

ity, and take normal precautions. Use

appropriate decontamination proce-

dures should exposure occur.

W A R N I N G

Toavoidpersonal injury, all

replacement and calibration proce-

dures should be performed by quali-

fied service personnel.

Introduction and Description

SORVALLCentrifuges

For rotors:

Remove tubes, bottles, and adapters from the rotor and

decontaminate rotor using an appropriate method. If tubes

or rotor caps are stuck in the rotor, or the rotor door is stuck,

notify Sorvall representative; be prepared with the name

and nature of the sample so the Sorvall Chemical Hazards

Officer can decide whether to authorize the rotor's return to

a Sorvall facility.

2. Complete Decontamination Information Certificate (SORVALL®

products Form No. IPDP-59 or E53603) and attach it to the

centrifuge or rotor before servicing or returning to Sorvall facil-

ity. Certificates are included in the back of this manual. Addi-

tional certificates are available from the local Account Repre-

sentative or Field Service Engineer. In the event that these

certificates are not available, it will be acceptable to include a

written statement certifying that the unit has been properly

decontaminated and outlining the procedures used.

If the centrifuge or rotor must be returned to a Sorvall facility:

1. Contact your Sorvall representative to obtain a Return Service

Order Number (RSO No.). Be prepared with the name and

serial number of the centrifuge or rotor and the repairs re-

quired.

2. Send item(s) with the RSO No. clearly marked on the outside

packaging to the address obtained from your Sorvall represen-

tative.

NOTE

United States federal regulations require that parts and

centrifuges

must

be decontaminated before being trans-

ported. Outside the United States, check local regula-

tions.

If a centrifuge or rotor to be serviced does not have a

Decontamination Information Certificate attached and, in Sorvall's

opinion presents a potential radioactive or biological hazard, the

Sorvall representative will not service the equipment until proper

decontamination and certification is complete. If Sorvall receives a

centrifuge or rotor at its Service facilities which, in its opinion, is a

radioactive or biological hazard, the sender will be contacted for

instructions as to disposition of the equipment. Disposition costs

will be borne by the sender.

NOTE

The Field Service Engineer will note on the Customer

Service Repair Report if decontamination was required

and, if so, what the contaminant was and what proce-

dure was used. If no decontamination was required, it

will be so stated.
