7. Keep the inside panels dry
To protect the inside of the unit from contamination, the inside panels should always be kept dry. If
water is spilled from the humidifying pan or if the door is kept open for a long period, condensation will
form on the panels, allowing bacteria or fungi to breed. If this occurs, wipe away the water with a dry
sterile gauze. Particularly, if the medium is spilled, wipe it up immediately and sterilize the area.
8. Fill the humidifying pan with sterile distilled water
Always use sterile distilled water to fill the pan. The RH PAN light on the control panel flashes when the
water level is low. Refill the sterile distilled water to the pan when the RH PAN light blinks. Note that
when low temperature water is poured, the chamber temperature drops significantly. Clean the pan
once a month.
9. Humidifying pan and pan cover
The humidifying pan and pan cover prevent the UV light from escaping. Make sure they are installed
even if you do not need humidity. Install the pan cover correctly since it affects the temperature
distribution and humidity recovery in the chamber.

BEFORE COMMENCING OPERATION
Connection of CO2 gas cylinder
WARNING
Check the gas type and ensure that it is fit for the purpose. Make sure that all pipes are
connected correctly and are not liable to become disconnected. Ensure that the gas pressure is
set at the specified value. Improper connection of the gas pipe or use of incorrect gas pressure
may result in leakage of CO2 gas. Elevated level of CO2 gas can be hazardous to health and may
lead to asphyxiation and risk of death.
Use a liquefied CO2 gas cylinder, not a siphon (dip tube) type. The CO2 gas should be 99.5% or more
pure.
Install a pressure regulator on the cylinder. Use a regulator rated at 25MPaG (250kgf/cm2G, 3600psiG)
on the primary side and 0.2MPaG (2.0kgf/cm2G, 30psiG) on the secondary side. Use the following
procedure to attach the incubator to the cylinder:
1. Using the gas supply pipe provided, connect the pressure regulator to the CO2 inlet located at the rear
left hand side of the CO2 incubator.
2. Set the CO2 pressure on the secondary side to 0.03MPaG (0.3kgf/cm2G, 4.3psiG). Excessive
pressure may cause disconnection of internal pipes inside the CO2 incubator which will result in leakage
of CO2 gas into the atmosphere. Elevated level of CO2 gas can be hazardous to health and may
lead to asphyxiation and risk of death.
3. Check that no gas is leaking at any point where the pipe connects with the CO2 regulator or the CO2
incubator.
Note:
The incubator, including the gas supply pipes and services must be examined at frequent intervals to
ensure they are safe. Ensure that items such as pipes are replaced if there is any sign of deterioration.
14
BEFORE COMMENCING OPERATION
Automatic switcher of CO2 gas supply line
An automatic switcher of CO2 gas supply line (MCO-21GC) is available as an optional accessory. This
kit switches the gas supply line when one CO2 gas cylinder is empty.
Note: The installation of MCO-21GC should be implemented by a qualified service personnel.
After attachment of MCO-21GC, do the following:
1. Connect a CO2 gas pipe to port A and B respectively. A connecting port for CO2 gas pipe is located
on the left back of the unit. (See page 9).
2. Connect a CO2 gas cylinder provided with a gas pressure regulator to each gas pipe. See page 14,
for the connection of the gas cylinder.
3. Open the valve of each gas cylinder.
4. Check that the CO2 gas supply line indicator on the control panel is lit by pressing the switching key.
5. Select a CO2 gas supply line (A or B).
6. When one cylinder is empty, the indicator is flashed, buzzer sounds, and “E01” and current chamber
temperature are displayed alternately on the control panel while the gas supply line is switched to other
one. To silence the buzzer, press the buzzer stop key (BUZZER).
7. Replace the empty CO2 gas cylinder.
Note: Exercise caution when handling empty CO2 gas cylinders as some gas can be still be left in the
cylinder.
This kit MCO-21GC detects that no more CO2 gas exists in a cylinder when the CO2 density in the
chamber is not increased for a while after opening of CO2 gas valve in the unit and switches the gas
supply line. The switching of supply line can be caused by some other reasons; blocking or restricting of
gas tube, reduction of CO2 gas pressure, or improper opening of CO2 gas cylinder, in spite of gas quantity
in the cylinder. Therefore, always check the gas quantity in the cylinder prior to disconnection.

3. Set the present correct temperature with the
key and key, then press the ENT key.
4. The unit automatically reverts to the display mode.
[Example]
If the displayed chamber temperature is 37.0oC (set value) and the actual temperature is 36.8oC.
1. Press the CAL key for about 5 seconds.
2. The “3” on the temperature indicator flashes, and the CO2 density indicator goes out.
3. Adjust the set value to the actual value of 36.8oC with the
key and key, then press ENT key.
4. The unit automatically reverts to the display mode.
Note:
It is important to accurately measure the temperature inside the unit when performing temperature
calibration. Particularly, the temperature gauge used must have an accuracy of 0.5 Class or better.
The temperature must be measured at several points.
The temperature setting must not change by more than ±1.0oC during calibration. If it exceeds this, an
error tone is emitted, the input data is ignored, and the unit reverts to the display mode. Consequently, if
it is necessary to change the temperature by more than 1.0oC, perform calibration in several stages over
a period of time.
CO2 calibration
Span setting
Span setting should be done under stable condition of temperature, humidity, and CO2 density.
1. Press the CAL key for about 5 seconds.
2. The third digit on the temperature indicator flashes, and the CO2 density indicator goes out.
3. Press the CAL key once again.
4. The third digit on the CO2 density indicator flashes, and the temperature indicator goes out.
5. Set the present correct CO2 density with the
key and key, then press the ENT key.
6. The unit automatically reverts to the display mode.
Note:
This calibration is available when the setting of CO2 density is 2% or more.
[Example]
For an internal CO2 density of 5.0% (setting) and a measured value of 4.5%.
1. Press the CAL key for about 5 seconds.
2. The third digit on the temperature indicator flashes, and the CO2 density indicator goes out.
3. Press the CAL key once again.
4. The third digit on the CO2 density indicator flashes, and the temperature indicator goes out.
5. Set the present correct CO2 density (4.5%) with the
key and key, then press the ENT key.
6. The unit automatically reverts to the display mode.

TROUBLESHOOTING
If the unit malfunctions, check out the following before calling for service.
The unit does not operate at all
1. The unit is not plugged correctly into a power outlet.
2. The circuit breaker at the power source is active.
3. A power failure has occurred?
The key operation is disabled
1. The key lock function is set in OFF mode.
If the alarm function operates
If the alarm function and the buzzer operates, check the cause using the following procedure.
[At the beginning of operation]
1. The chamber temperature is not equal to the set value.
2. The chamber CO2 density is not equal to the set value.
a. The secondary pressure of the pressure regulator is not equal to the set value (0.03MpaG,
0.3kgf/cm2G, 4.3psiG).
b. The tube is not connected securely between the pressure regulator and the unit.
[During operation]
1. The upper limit alarm temperature is not set at least 1oC higher than the set chamber temperature.
2. The set temperature value was changed, or the door was left open for a long period. A low
temperature load was placed inside the unit. In this case, if the unit is left as it is, the alarm will
eventually clear itself.
3. The gas tube has slipped off.
4. The set value of the gas density was changed.
5. The gas cylinder is empty. Check the primary pressure of the CO2 cylinder once a week.
If the chamber temperature is not equal to the set temperature
1. The temperature in the vicinity is too high. The ambient temperature must always be at least 5oC less
than the set temperature.
2. The outer door was closed while the inner door was left open.
If the gas density does not coincide with the set value
1. The secondary pressure is not set to 0.03MPaG (0.3kgf/cm2G, 4.3psiG).
2. The gas tube is clogged or chinked.
If the chamber humidity does not rise
1. The humidifying pan is not filled with sterile distilled water. (Always use sterile distilled water.)
2. The humidifying pan cover is not installed correctly.
If the CO2 consumption is too much
1. The door is opened frequently.
2. There is any gas leakage at the connection or pin hole on the tube. It is recommended to replace the
tube once a year.
3. The gasket of the inner door is not completely sealed.
4. The access port at the upper left corner is opened.
If normal cultivation cannot be done and chamber gas density is suspect
1. The environment around the unit is not normal. The source of the contaminated gas is nearby.
2. The unit is installed in an enclosed space.
If it takes much time to recover the gas density
1. HEPA filter is provided in the gas piping. If it takes much time to recover the gas density even though
the gas pressure is normal, it may be that dust on the HEPA filter prevents the gas flow. Consult the
Sanyo dealer or agent.
