This product is not intended for a life support function.

This product is intended to be used in hospitals and clinics.

This product has no Radio Transmitter (Intentional Radiator) functions.

This product is not intended for electromagnetic shielded rooms only.

This product does not intentionally apply RF energy for its function.

This product does not intentionally receive RF energy for its function.

The liquid level controllers used with these freezers operate from 12 VDC. Disconnect

the electrical power cord from the outlet before attempting any service.

For more detailed information concerning safety precautions and safe practices to

be observed when handling cryogenic liquids, consult CGA publication P-12 “Safe

Handling of Cryogenic Liquids” available from the Compressed Gas Association: CGA

website: www.cganet.com; CGA customer s1.703.788.2700;

WARNING:

Electrical shock can

kill. Do not attempt

any service on these

units without first

disconnecting the

electrical power

cord.

The

CS100 SERIES Control System

can monitor and control the liquid nitrogen level range in the cryostorage

unit you have selected. CS100 SERIES Control Systems are designed to work with Worthington Industries

Cryostorage Systems. The features are designed to provide a safe environment for samples while at the same time

tracking all relevant information associated with the freezer. This control provides a complete historical record of

the environment in your unit and therefore, the environment in which your samples have been stored in this system.

This controller features a vacuum fluorescent display. The addition of a liquid nitrogen supply and inventory control

racks for systematic retrieval of stored product completes the total Cryostorage System.

Worthington Industries Cryostorage Systems are designed for applications where extremely low temperature

storage of biological products is required. They are also appropriate for industrial or other applications where

liquid nitrogen temperatures and high capacity are needed.

Before beginning installation or operation of this CS100 SERIES Control System, make sure that you read and

understand this manual as well as the operating and safety instructions for the cryostorage unit you will be using

with this controller.
