Temperature calibration

䋨1䋩 Press CAL key for approx. 5 seconds.
䋨2䋩 The top (the 3rd) digit of temperature display is flashing, other digits will go off.
䋨3䋩 Set the present correct temperature with key and key. Press 㩷 ENT key.

䋨4䋩 The display will automatically revert to the present temperature.

䈀Example䈁 If the internal temperature display shows 37.0㷄䋨the set value䋩and the

actual measured value is 36.8㷄,

㽲㩷 Press㩷 CAL 㩷 key for approx. 5 seconds.
㽳 The “3” (top digit) of temperature display is flashing, other digits will go off.
㽴 Set the displayed value at 36.8㷄 with key and key, then press ENT

key.

㽵 The display will automatically revert to the present temperature.
䋨Note䋩
䊶㩷In temperature calibration, it is important to accurately measure the internal temperature.

Particularly, for the thermometer used, its grade of accuracy should be than 0.5 class. The
measure should be carried out at the center of the chamber.

䊶㩷The temperature calibration range is between the set value 㫧1.0㷄. If the value over this

range is input, an error tone will be emitted, the input data will be ignored, and the display
will revert to the present temperature. Therefore, if you need to calibrate more than 1.0㷄,
you should repeat above procedure several times.

The displayed internal CO

2

is higher than the actual when the internal temperature and
humidity are not stabled (reached) just after the unit started running.
It is not abnormal because the CO

2

sensor is heat conducting type.

After the internal temperature is set to desired value and CO

2

is set to 0%, pour 1.5L distilled
water into the humidifying pan then run the unit for approx. 8hours to be internal temperature
and humidity stabled.
Finally perform CO

CO2 Calibration

Prior to calibration performed, make sure there is not CO

2

in the unit and the internal
humidity is stable. If you perform calibration with the internal humidity unstable, you may get
the CO

2

density incorrectly.

Perform calibration before CO

2

is injected.

Never perform CO

2

calibration before O

2

calibration is completed.

1. Procedure
(1) Pour sterilized water into humidifying pan and operate unit for approx. 10hrs with SV

37㷄. Ensure the internal humidity should be stabled in 90% or higher.

CO

2

setting should be 0%.

<Note> 1) Never open the door during the operation to stabilize internal humidity.

2) It takes approx. 5hours to stabilize internal humidity since the operation started.
You cannot get the correct value for CO

NOTICE

Prevention of contamination

In servicing for CO

2

incubator, it is important to prevent from contamination.

䋨1䋩㩷More than 90% of contamination in CO

2

incubator is caused by mold. Mold is a kind of

true fungi, it has high increasing power under high temperature and high humidity.

Accordingly, it is easy for mold to increase inside CO

2

incubator. Those increased mold

eat up culture (mainly animal cell), eventually precious test sample will be killed. Cell that

is independent from ecosystem is also independent from immune system, it has no

immunity against all.

䋨2䋩㩷Precautions for mold increasing

There are many cases that mold multiply by eating fat on the fingers as a source of

nutrient in CO

2

incubator.

Therefore,

㽲㩷Be sure to wash and sterilize your hands prior to servicing. Use 70䋦 ethanol.
㽳㩷In installing, sterilize the inside wall and shelves after removing shelves, duct,

humidifying pan and so on with 70% ethanol.

䋨3䋩㩷In the case that mold has already multiplied.

Sterilize the interior (walls) and shelves with 70% ethanol after removed all items from
the chamber as same as (2)-㽳 above.

And you should sterilize again after 24 hours once sterilized, when the root of spore is

geminated, because it is too difficult to remove spore of mold. Repeat sterilization is

effective.

In general, stainless steel is known that it is not easy 䋨hard䋩 to rust.

However depends on the conditions, rust might generate.

When you remove rust, we recommend the following agents.

Besides, the surface may become foggy.

Recommended agent:
1䋮 Cream cleanser 䇸Gif䇹 䋨Nippon Leva䋩
2䋮 Picasso #SUS300-W 䋨Chemical YAMAMOTO䋩
䋼Picasso has greater capability of clean for rust than Gif.䋾

The setting of UV lamp ON time is
memorized and the current chamber
temperature is displayed.

<<NOTE>>

• The UV lamp ON time is settable between 0 to 30 minutes. However, it is recommended to set 5
minutes in general.

• The UV lamp ON time is settable between 0 to 30 minutes (000 to 030). The UV lamp is not
turned ON if the setting is 000.

• The UV lamp is turned off when the outer door is opened while the lamp is on. The lamp is
turned on for pre-set duration after the outer door is closed.

• The condensation in the chamber can be caused and/or the chamber temperature distribution can
be affected due to the heat from UV lamp when the setting of UV lamp ON time is longer than 5
minutes or the only the outer door is opened/closed repeatedly. In such case, the life of UV lamp
is shortened.

• In the procedure 2 above, pressing CAL key for 5 seconds causes the calibration mode. In this
mode, it is possible to calibrate the temperature and CO

2

density, and miss operation of the key
may affect the basic performance of the unit. Take care of the key operation. Even if the key is
operated wrongly, the unit returns to the current value display mode automatically when no key is
operated for 90 seconds. In this case, the setting not entered by pressing ENT key is not
effective.

12. Check that the UV lamp is turned on.

Check the UV lamp is turned on by the following procedure:
