START-UP OF UNIT
Follow the procedures for the initial and consequent operations of the unit.
1.
Make sure that both of the power switch and the battery switch for power failure alarm are OFF (factory
setting is OFF).
Note:
When the power switch is ON and the battery switch for power failure alarm is ON, the power
failure alarm is activated (refer to page 47).
2.
(When an optional backup cooling kit MDF-UB5 is installed) Turn OFF the backup power switch.
3.
Before putting some contents to cryopreserve into the chamber, connect the power supply cord to the
outlet.
4.
Turn ON the power switch to start operation of the unit.
5.
Turn ON the battery switch for power failure alarm.
Note:
When the battery switch for power failure alarm is OFF, “Err09: Battery Switch is OFF.” is displayed
in the message display field. By turning ON the battery switch for power failure alarm, this message
disappears.
6.
Set the chamber temperature and the high/low alarm (refer to pages 22~23).
Note:
Keep the ambient temperature between 5
o
C to 30
o
C. The chamber temperature may not reach
set temperature when the ambient temperature is higher than 30
o
C.
7.
Make sure that chamber temperature is cooled to the set temperature.
8.
Do the alarm test. Make sure that the buzzer sounds by pressing Buzzer key for 5 seconds. Press
Buzzer key again to stop the buzzer and the alarm test finishes.
9.
(When an optional backup cooling kit MDF-UB5 is installed) After the chamber temperature reaches
the set temperature, turn ON the backup power switch.
Note:
When operating this unit for the first time or after not using it for an extended period of time, it is
required 3 days (72 hours) operation of unit before using the backup cooling kit. The capacity of internal
battery for backup cooling kit may be less or flat by electric discharge.
10.
(When an optional backup cooling kit MDF-UB5 is installed) Set the injection set temperature of the
backup cooling kit by adjusting the temperature setting knob.
11.
Put the contents to cryopreserve into the chamber.
Note:
• Do not put a large amount of contents to cryopreserve at a time. Put little by little to prevent rapid rise of
the chamber temperature.
• Do not put a large amount of warm contents to cryopreserve. The rise of the chamber temperature may
have a bad influence on the contents in the unit.
• This unit is designed only for low temperature storage of medical/biotechnology samples (ex. cells) or
reagents. Do not use for the purpose other than above (ex. freezing of regenerating agent).
• In case some optional inventory racks are in the chamber, be careful not to drop inventory rack when
pulling out it.
