13

Connection of CO2gas 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 CO2gas. Elevated level of CO2 gas can be hazardous to health and may
lead to asphyxiation and risk of death.
1. Use a liquefied CO2 gas cylinder, not a siphon (dip tube) type. The CO2 gas should be 99.5% or more
pure.
2. Install a gas pressure regulator (optional accessory MCO-100L) on the cylinder. Use a regulator
rated at 25 MPaG (250 kgf/cm2G, 3600 psiG) on the primary side and 0.2 MPaG (2.0 kgf/cm2G, 30 psiG)
on the secondary side.
3. Using the gas supply pipe provided, connect the CO2gas pressure regulator to the connecting port for
CO2gas pipe located at the rear left side of the CO2incubator.
Note:
If CO2is supplied to multiple CO2incubators from a single gas cylinder, a CO2solid will be formed in the
gas pressure regulator. The gas pressure regulator safety valve will operate, and there may an explosive
sound.
When the MCO-21GC is not mounted
Using the gas supply pipe that is provided, connect the CO2gas pressure regulator for the CO2gas
cylinder to CO2gas pipe connection port A on the incubator. After connecting the pipe, check to make
sure that no gas is leaking.
When the MCO-21GC is mounted
Connect a pair of CO2gas cylinders with CO2gas pressure regulators independently. The gas supply line
will be switched automatically. Connect the main cylinder to port A and the reserve cylinder to port B. After
connecting the cylinders, check to make sure that no gas is leaking.
4. Set the CO2pressure on the secondary side to 0.03 MPaG (0.3 kgf/cm2G, 4.3 psiG) (at gas injection).
Excessive pressure may cause disconnection of internal pipes inside the CO2incubator 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. The repair of the incubator will be necessary if the
internal pipe is disconnected.
4. Check that no gas is leaking at any point where the pipe connects with the CO2regulator 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.

PREVENTING CONTAMINATION
To prevent contamination of the chamber, select an appropriate location for installation as well as the
complete disinfection of the chamber components.
●Avoid hot and humid location
Avoid location with high temperature and/or humidity as the presence of bacteria in the air is greater than
in normal environment.
●Avoid drafty location and location with many passers-by
Avoid locations near doors, air conditioners, fans, etc., where slight breezes can facilitate the entry of
bacteria into the chamber.
●Installation in a sterile room
To get the cultivation more efficiently, install the incubator in a sterile room.
●Use clean containers
The contamination is mainly caused by the containers such as Petri dishes or bottles stored in the
chamber. Always keep the containers clean.
●Always keep the chamber clean
The condensation may be caused on the inside of the door by spilled water form humidifying pan or
opening of outer door for long period. Wipe off the condensation completely with a sterile dry gauze.
Especially when the culture medium is spilled, clean and disinfect the chamber immediately. Refer to
page 27 “Routine maintenance” for details.
●Keep the inside panels dry
To protect the inside of the incubator from contamination, the inside panels should always be kept dry. If
water is spilled from a humidifying pan or if the door is kept open for a long period, condensation will form
on the panels, allowing germs to breed. In such a case, wipe away the water with a dry sterile gauze.
Particularly, if the medium is spilled, wipe it up immediately and sterilize the area.
●Fill the humidifying pan with sterile distilled water
Always use sterile distilled water to fill the pan. The water level alarm lamp (RH PAN) on the control
panel blinks when the water level is low. Refill the sterile distilled water to the pan when the water level
alarm lamp (RH PAN) blinks. Note that when low temperature sterile distilled water is poured, the
chamber temperature drops significantly. Clean the humidifying pan once a month.
●Do not place the incubator in the direct air flow from an air conditioning system
Air from an air conditioning system may cause condensation and lead to possible contamination.
15

PRECAUTIONS FOR CULTURES
●Do not subject to direct air flow
Do not allow the air for air conditioning to hit the incubator or door directly. Direct hit may cause
condensation or contamination.
●Allow adequate space between the cultures
When storing cultures in the chamber, keep the Petri dishes or bottles containing the cultures sufficiently
apart from each other to allow adequate air circulation. Inadequate space may result in uneven
temperature distribution and CO2 concentration in the chamber.
●Stored materials
Never place acid or alkaline materials or materials that release corrosive gas in the chamber. Such
materials can cause failure resulting from discoloration or corrosion.
●Always shut the inner door
Shut the inner door completely, and then shut the outer door. If the inner door is not closed completely,
even if the outer door is closed, the incubator will fail to exhibit its maximum performance. And close the
doors gently. Rude closing may cause spillage of medium, incomplete closing, or damage of gasket.
●Open/close the doors gently
Ensure you close the doors gently. Robust closing may cause spillage of medium, incomplete closing,
or damage of gasket. Also, before opening the inner door, check that the UV light is OFF
(MCO-18AC(UV) or when an optional UV system kit MCO-18UVS3 is installed).
●Take care of the inside of the outer door.
It may get hot.
●Never lean or press on the glass.
Broken glass due to intentional force may cause injury.
●Alarm
Always investigate the cause and fix the alarm condition immediately when the alarm is activated. Refer
to page 25 for alarm details.
●Fix the tray supports and trays securely
Incomplete installation may cause injury or damage.
16

START-UP OF INCUBATOR
When start the test operation or the operation, follow these steps as below.
1. Install the incubator referring to “INSTALLATION” on page 13.
2. Remove all transportation packaging materials and tapes on the attachments in the chamber. Then
clean and sterilize the chamber and inner attachments. Refer to “Cleaning the chamber and inner
attachments” on page 27.
3. Add approximately 1.5 L of sterile distilled water to the humidifying pan. (Refer to page 30.)
4. Turn ON the power switch on the rear left side.
Note:
The humidity in the incubator chamber is adjusted to the optimum setting. To prevent condensation on
the surface inside chamber and the inner door, there is a low-temperature area under the humidifying pan
in the bottom of chamber to recondense evaporated moisture. Condensation may occur around the
humidifying pan at the bottom of the chamber, but this does not indicate a problem.
17

SETTING THE CHAMBER TEMPERATURE AND CO
2
DENSITY
Table below shows the basic procedure for setting the chamber temperature and CO2density. The
upper limit alarm temperature setting is also shown in the table. Perform key operations in the sequence
indicated in the table. The example in the table is based on the assumption that the desired temperature
is 37oC and CO2density is 5%. Adjustment of the upper limit regulator should be executed after the
chamber temperature reaches the stable condition.
Note:
• The incubator is set at the factory so that the chamber temperature is 37oC and CO2density is 0%.
• When starting the incubator for the first time or after not using it for an extended period of time, allow at
least 8 hours for the chamber temperature, humidity, and CO2sensor to become stable after setting the
desired chamber temperature at 0% CO2density. Then change the setting to the desired CO2density.
