The CS200 SERIES Control System can monitor and control both the liquid nitrogen level and the vapor
temperature range in the IC Biomedical Cryostorage Freezer you have selected.
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.
Before beginning installation or operation of an IC Biomedical Cryostorage Freezer with CS200 SERIES
Control System, make sure that you read and understand the User Manual that contains safety
instructions for the cryostorage unit you will be using with this controller.
Freezer Installation
•
Connect a transfer line (included with freezer) from an LN2 supply tank to the fill connection at
the rear of the freezer.
•
The liquid nitrogen supply pressure at the inlet to the freezer should be in the range of 10 psig
(0.7 bar/69 kPa) to 22 psig (1.5 bar/152 kPa) for optimum performance. Higher operating
pressures will increase transfer losses and create excessive turbulence of the liquid in the
freezer, which can generate false signals to the liquid level controller causing the freezer to under
fill. In "liquid phase" storage applications, excessive turbulence can cause splashing which could
result in personal injury.
•
After the transfer hose is securely coupled to the freezer and supply tank, ensure all connections
are leak free by opening the valve of the LN2 supply tank and apply a soap and water solution to
each field joint. You should not see bubbles forming at any joint. Wipe away excess soap and
water when finished.
•
Connect the power supply to the CS200 SERIES Control System and then plug the power supply
into a surge-protected wall outlet.
•
When the freezer is powered up, the control display will illuminate and the fill valve will open to
allow LN2 to enter the freezer. LN2 will start flowing into the freezer cooling it.
•
It is recommended that the freezer be allowed to cool for 48 hours before putting any product in
the freezer.
•
Should any alarms occur, contact your IC Biomedical Distributor.
Note: Liquid level and temperature sensors are positioned by during the manufacturing of the
freezer. If these need to be adjusted, refer to the CS200 SERIES technical manual or contact your
IC Biomedical Distributor.
