5.2 – Managing Freezer Contents
The SU105UE freezer is designed for long-term storage of sample materials with ultra-
low, well-regulated temperature storage requirements. Many times these materials
are collected in cassettes or other carriers for ease of inventory and transportation.
Such carriers have respective safety requirements and best practices for usage that
become part of the requirements for managing freezer contents.
• The temperature setpoint for the freezer should be changed as appropriate for the
materials being stored using the GUI as described above, as may the high and low
temperature limits, as necessary.
• The current freezer temperature is displayed on the Home control panel screen,
and a temperature history chart is available on the control panel screen.
• Materials may be placed in the freezer in any convenient arrangement that does not
block the access port, interfere with the door gasket, or prevent the door from closing
completely.
• The Safety Precautions section of this Operating Manual is especially pertinent to this
component of SU105UE freezer operation, as ultra-low temperatures are encountered
directly. The user is directed to review those Safety Precautions.
5.3 – Cleaning
Cleaning the Freezer Surfaces
• Clean the exterior surfaces of the SU105UE cabinet as needed by using a soft cloth
and mild detergent. Do not use solvent (such as bleach) or harsh abrasive cleansers
or pads.
• When appropriate, remove ice that accumulates inside the freezer by defrosting it.
— Transfer the contents of the freezer to alternate storage, switch off the power to
the freezer and wait for the ice to melt.
— Wipe up moisture with a clean cloth. If the freezer door can be left ajar safely,
defrosting will be more rapid.
— After defrosting the freezer, switch the power back on. When the temperature
reaches the setpoint, return the contents to the freezer.
• Note the Safety Precautions section of this Operating Manual while defrosting
the freezer.
