START-UP OF UNIT
The following procedures should be adhered to for initial start-up and continuous operation.
1. Connect the unit to dedicated power supply. Do not put any product in the unit at this time.
2. Set the desired temperature. The unit is preset to operate at -20°C. This is the optimal storage
temperature to maintain vaccine and biologic products within -15°C to -25°C throughout the usable
storage area.
3. Confirm that the chamber temperature is at the desired temperature.
4. When you are satisfied that the unit is working correctly, begin slowly placing product into the chamber to
minimize the temperature rise. Avoid long or excessive door openings to insure stored product integrity.
OPERATING INSTRUCTIONS
Temperature Setting
Table 2 shows the basic operation method. Perform key operation in the sequence indicated in the table. The
example in the table is based on the assumption that the
freezer temperature is -18 o C.
Note: The unit is set at the factory at -20 o C.

Note:
If no key has been pressed for 90 seconds in the temperature set mode, the display mode returns automatically
to the temperature display mode. In this case, the chamber temperature setting is not changed. The freezer
temperature can be set in the range between -15°C and -25°C. The guaranteed temperature with no load at an
ambient temperature of 22°C is -15 to -25°C.
