3. Operation Setup & Guidance
Before powering ON the unit, check that the electrical connections have been made correctly
➢This manual is part of the product and should be kept near the freezer for easy and quick
reference.
➢To set the DATE/TIME or LANGUAGE, refer to USER MENU in (section 3.2)
To run a continuous rotating cycle, (adding product for freezing and remove product when
frozen for further processing) the Time Cycle option should be used.
For fastest freezing using the Time Cycle,
➢Select an Air Temp. of -40°C, a Fan setting of 10, and a T Storage of -40°C.
➢Selecting a Cycle Time of 30 minutes will ensure the device has reached the target Air
temperature. See (Section 3.1) STARTING CYCLE
Upon expiration of the 30 minute cycle, the unit will sound an audible alert indicating the initial freeze
cycle is complete at which time the freezer will transition into Preservation Mode and hold at the T
Storage Temperature of -40°C until the user ends the cycle. The user may remove product at will as
the device is in either Freezing Mode or Preservation Mode.
LOADING FOR OPTIMAL PERFORMANCE
➢When loading plasma products onto each shelf, take care to lay the product in such a manner to
maximize airflow and reduce thermal load, no more than 3500 mL of product should be loaded on
each shelf. Do not place product directly on the base or against the walls, doors, or fixed guards
of the unit.
➢Load product at ambient temperature gradually to allow faster freezing.
➢Do not block the motor compartment air vents. Do not lay objects on the top of the equipment.
➢Limit the frequency and duration of door opening, each time the door is opened the internal
temperature will increase.
Please Note.
➢During loading / unloading, if the door is kept open longer than 60 seconds a
Door alarm will sound.
➢Ensure product loading does not affect airflow.
➢A mindful sense of urgency should be used when inserting / removing trays from
the freezer. The longer the door is open, the warmer the interior gets. But
ALWAYS work safely!
➢During the preservation cycle, the unit will enter a defrost cycle every 4 hours
The defrost cycle can last approximately 10 minutes during which the evaporator
coil temperature may breifly reach 5°C (you may see a slight rise in cabinet
temperature as well. During a defrost cycle, door opening will increase the
temperature even more) On termination of the defrost cycle, the unit will
automatically reenter a freeze / preservation cycle and the cabinet air
temperature will quickly drop back to normal range.
➢The Freezer is set to operate with a factory default to the Celsius temperature
scale. In the event that Fahrenheit is required, Contact Follett Technicial Services
(877)-612-5086.

19
➢If an alarm occurs due to extended door open time or any other reason, an alert icon will
illuminate on the upper Right corner of the screen and the buzzer will activate (Section 4.2)
➢Click on the alarm icon to see details.A message box will appear with the alarm code. Use a
single tap on the alarm ICON to acknowledge / silence alarm. The alarm ICON will remain lit after
the alarm has been acknowledged. To “CLEAR” the alarm, the unit must be put into the
“STANDBY” mode and then restarted.
➢A second tap may terminate the cycle requiring the cycle be started again. (Section 3.1)
STARTING CYCLE
➢If a cycle is accidently terminated a new cycle must be initiated and can be started immediately.
3.1 STARTING CYCLE
Power up the unit, the controller will start to load the software, it will then put the screen into the
Home Page view.
From the Home Page screen touch the START CYCLE icon:
The cycle settings menu view will then appear on the screen:
