Note: Incubating on a leaning tray may have a bad influence on the cultivation. Shrink Leveling feet Stretch Fig. 3 5. Ground the incubator. Ground the incubator during installation to prevent electric shock in case the insulation is not sufficient. If there is no ground wire at the location, consult with qualified service personnel. When a ground must be installed If a grounded 3-pole outlet is not available, then a ground must be installed. Consult with qualified service personnel. WARNING To prevent electric shock, always ground the incubator. If grounding is not possible, then have a ground installed by qualified personnel. If the incubator is not grounded, it may result in electric shock. Never connect the ground wire to a gas pipe, water pipe, lightning rod, or telephone ground wire. Doing so may cause electric shock. Installing a ground fault circuit breaker If using the incubator in the location with moisture or humidity cannot be avoided, then it is recommended that a ground fault circuit breaker be installed in the power supply circuit (i.e., the power supply at the incubator). Have the circuit breaker installed by qualified service personnel. CAUTION Do not climb on the incubator or place objects on top of it. Doing so may damage it or cause it to fall over, resulting in injury. 18 In case of double stack For stacking the incubators surely, refer to the procedure included with the optional double stacking bracket MCO-170PS or the stacking plate MCO-230SB. Wire Hooks Note: When stacking incubators, fix two hooks on the rear of the upper incubator to the wall by wire or chain, to prevent falling over (Fig. 4). Note: When stacking the incubators with our CO2 incubator or O2/CO2 incubator other than this product, use the stacking plate MCO-230SB. Refer to table 11 and 12 on page 90. Fig. 4 When the incubator is not in use Empty the water from the humidifying pan and remove moisture from the chamber. Make sure that the chamber is completely dry before closing the doors. Failure to do so may result in damage. Before moving the incubator Before moving the incubator, empty the water from the humidifying pan, disconnect the power supply plug from the outlet, and make sure that the cord will not be damaged. Failure to do so may result in electric shock or fire. 19 INSTALLATION Connecting CO2 gas cylinder WARNING When connecting a gas cylinder to the incubator, confirm the gas type. Confirm that the connections are secure and that no gas will leak. Be sure to use the specified pressure. Using an incorrect gas or pressure may result in explosion or fire, or in gas poisoning or oxygen deprivation due to gas leak. Install the incubator in a location with adequate ventilation. If adequate ventilation cannot be provided, then install an alarm system using CO2 and O2 densitometers. 1. Get a CO2 gas cylinder ready and install an optional gas regulator MCO-010R. Note: · Use a liquefied CO2 gas cylinder (at least 99.5 % pure). The siphon (dip tube) type cannot be used. · When MCO-010R is not available, install a gas regulator rated at 25 MPa(G) (250 kgf/cm2(G), 3600 psi(G)) for the primary side, and 0.25 MPa(G) (2.5 kgf/cm2(G), 36 psi(G)) for the secondary side. 2. Using a gas tube that is provided, connect the connecting port A for CO2 gas pipe and the gas regulator of the CO2 gas cylinder. For details on installing the optional automatic CO2 cylinder changeover kit (MCO-21GC), refer to page 74~76. Lower right side Connecting port A for CO2 gas pipe Note: · By using 2 tube bands that is provided, connect the gas tube tightly to prevent it from coming off. · Make sure that the gas tube is not folded. · If the CO2 gas is supplied to multiple CO2 incubators from a single gas cylinder, a CO2 solid will be formed in the gas regulator. The gas regulator safety valve will operate, and there may an explosive sound. 3. After connecting the gas tube, make sure that no gas is leaking (ex. by using a gas leak detection spray). 4. Set the CO2 gas on the secondary side to 0.03 MPa(G)~0.1 MPa(G) (0.3 kgf/cm2(G)~1 kgf/cm2(G), 4.4 psi(G)~14.5 psi(G)) for gas injection. Recommended pressure: 0.03 MPa(G) (0.3 kgf/cm2(G), 4.4 psi(G)). Note: As the pressure increases, the CO2 gas density control range will increase. Excessive pressure may cause gas supply lines inside the incubator to come loose, which may result in gas poisoning or oxygen deprivation due to gas leak. If gas lines come loose, the incubator must be repaired. 5. When there is no CO2 gas left and the CO2 gas empty alarm is activated, replace the empty gas cylinder to a new one. Note: When an optional gas auto changer MCO-21GC is installed, it switches the empty CO2 gas supply line to the other automatically. Refer to page 75~76. Note: The gas lines connected to the incubator will degrade over time. If any deterioration or abnormalities are found during inspection, replace the lines immediately. 20 BEFORE COMMENCING OPERATION Initial cleaning method Before using the incubator for the first time, clean dirt (tape residue, smear, etc.) from the chamber and the inner attachments thoroughly. To keep the chamber clean is essential to get the proper performance out of the incubator. Use the following steps to clean the incubator properly. 1. Remove the inner attachments, referring to “Removing inner attachments” on page 22. 2.

Bent down 24 Fig. 4 Filling humidifying pan Use the following procedure to fill the humidifying pan with water or to replace water in the humidifying pan. 1. Pull out the humidifying pan toward you. (Fig. 1) 2. Dispose of the remaining water in the humidifying pan and clean the humidifying pan with a diluted detergent. Then rinse it thoroughly with distilled water and wipe it with alcohol for disinfection. 3. Wipe all moisture from the bottom of the chamber. Fig. 1 4. Return the humidifying pan to the chamber and pour sterile distilled water (approx. 1.5 L, preheated to 37 C). (Fig. 2) Fig. 2 Note: · Operation with no water for humidifying may increase the chamber temperature than the set temperature temporarily. · Preheat the water to 37 C to be poured into the humidifying pan. Adding low-temperature water will lower the temperature and humidity in the chamber. · Install the humidifying pan in a longitudinal direction as its shorter side is placed in the back. · Refill the humidifying pan with water early when the volume of water is decreased. · Mixing any reagent in the water for humidifying may have a bad influence on the cultivation. Especially when using the UV lamp, do not use any reagent. Because the UV light may deteriorate the reagent mixed with the water for humidifying. 5. Set the humidifying pan with the inner side flush against the back, and close the inner door and the outer door. Note: Set the humidifying pan with the inner side flush against the back. The humidity control bar in the duct keeps at low temperatures and inner moisture is recondensed. Slide the humidifying pan down right under the humidity control bar, otherwise the recondensed water drops will directly fall to the chamber bottom and will pool in the chamber bottom. When the pooled water evaporates, it may leave a white mark on the chamber bottom. This is not a malfunction. Wipe it off with alcohol-soaked gauze or unwoven cloth. When the mark cannot be removed, scrub the mark off with using a cream cleanser. 25 FOR BETTER CULTIVATION Precautions for cultures Leave space between culture containers. Always leave space for ventilation between culture containers (Petri dishes, flasks, etc.). Inadequate spacing may result in uneven temperature distribution and CO2 gas density. Do not place harmful materials in the chamber. Never place samples that release acidic, alkali, or corrosive gas in the chamber. Doing so may cause damage resulting from discoloration or corrosion. Close the inner door. Always close the inner door before closing the outer door. Failure to close the inner door will adversely affect performance even if the outer door is closed. Open and close the doors gently. Always open and close the doors gently. Closing the doors forcefully may cause spillage of the culture medium, incomplete closing, or damage to the gasket. Before opening the inner door, check through the glass to confirm that the UV lamp is OFF (if the MCO-230AICUV or the optional MCO-170UVS is installed). Be careful when closing the outer door. Use the handle when closing the outer door. Holding the door in other places may cause injury by getting fingers caught in the door. Do not lean on the outer door. Doing so may result in injury from the outer door coming loose or the incubator falling over, or it may cause current leakage or electric shock. Be careful of the inside of the outer door. The inside of the outer door may become hot. Avoid using excessive force on the inner door. Do not put your hand on the glass, poke it with sharp objects, or apply strong force. Doing so may result in injury from breaking the glass. Check the cause of any alarm buzzer. If an alarm buzzer sounds while the incubator is in use, immediately check the cause of the alarm. For details on what may cause an alarm buzzer to sound, refer to page 82~84. 26 Preventing contamination To prevent contamination of the chamber, select a suitable installation site. Avoid locations with high temperatures or humidity. Avoid locations with high temperatures or humidity, because of a greater presence of microorganisms in the air. Avoid locations with passers-by or drafts. Avoid locations near doors, air conditioners, fans, etc., where passers-by or drafts can facilitate the entry of microorganisms into the chamber. If possible, use a cleanroom. To achieve a better culture, it is recommended that a cleanroom be used if one is available. Use clean containers. The greatest cause of contamination is dirty containers for cultures. Be careful not to get containers or trays dirty when taking them in and out. Keep the chamber clean. Wipe off any fingerprints. If water spills from the humidifying pan, or if the doors are left open for a long time, condensation may form on the inside of the doors. If that occurs, wipe off the condensation with a dry sterile gauze. In particular, clean and disinfect the chamber if the culture medium is spilled. For details, refer to “ROUTINE MAINTENANCE” on page 81. Use sterile distilled water in the humidifying pan. Always use sterile distilled water in the humidifying pan. Do not use ultrapure water, because it may cause red rust-like particles in the humidifying pan. Clean the humidifying pan once a month. In some cases, an antibacterial ingredient may precipitate in the water for humidifying. This is not a malfunction. Keep the incubator out of direct airflows from air conditioners or fans. Cool airflow from an air conditioner may cause condensation and lead to possible contamination. 27 CORRECT OPERATION Use the following procedure to start trial operation or actual operation of the incubator. 1. Install the incubator correctly, referring to “INSTALLATION” on page 15 to 20. 2. Remove the packing materials from the chamber and inner attachments. Clean and disinfect the chamber and all the inner attachments, referring to “ROUTINE MAINTENANCE” on page 81. 3. Add approximately 1.5 L of sterile distilled water to the humidifying pan (Refer to page 25). 4. Connect the removable power supply cord that is provided, to the port on the lower rear side. 5. Connect the removable power supply cord to the outlet. 6. Turn ON the power switch on the lower right side of the incubator. 7. (MCO-230AICUV or when an optional UV system set MCO-170UVS is installed.) Set the frequency of a power supply on the LCD touch panel (Refer to page 57~58). WARNING Always use the removable power supply cord that is provided. Other power supply cord may cause electric shock or fire. The provided removable power supply cord is only for this product. Never use it for any other products. When the incubator is not in use Empty the water out of the humidifying pan and remove moisture from the chamber. Make sure that the chamber is completely dry before closing the doors. Failure to do so may result in damage. Before moving the incubator Before moving the incubator, empty the water out of the humidifying pan, disconnect the power supply plug from the outlet, and make sure that the cord will not be damaged. Failure to do so may result in electric shock or fire. 28 BASIC OPERATION ON LCD TOUCH PANEL ●Operation from Menu key ■Menu screen Page ♦Set → ■Stand-by Setting screen ♦Log → ■Log screen ♦Chart ♦Door Opening Export ♦Setting ♦Alarm ♦Alarm Export ♦Auto-Lock → ♦KeyLock → User ■Auto-Lock screen*1 ■Key Lock screen ■Auto-Lock User screen (Export) (Export) (Export) (Setting) (Display) (Export) Chamber temperature log CO2 density log Outer door opening log Log interval, Unique ID Alarm log (can be exported) Alarm log 45~47 45~47 45~47 41~42 48~49 50~52 (Setting) Auto-lock ON/OFF, User-ID ON/OFF 69~73 (Setting) Key lock ON/OFF, password 34~37 (Setting) User-ID, password 67~69 42~44 → ■Tools#1 screen ♦Temp./Gas Calibration ♦Alarm Setting #1 ♦Alarm Setting #2 ♦UV Setting*2 ♦STD Gas Setting*3 ♦STD Gas Calibration*3 ♦Tools#2 42~44 42~44 → ■Lock screen ♦Auto-Lock ♦Tools#1 (Display) Chamber temp. log graph (can be exported) (Display) CO2 density log graph (can be exported) Outer door opening log graph (Display) (can be exported) → ■Export screen ♦Actual Temp. ♦Actual CO2 Level ♦Door Opening ♦Lock 32~33 → ■Chart screen ♦Actual Temp. ♦Actual CO2 Level ♦Data (Setting) Temp., CO2 density, high limit temp. alarm Don’t push (See Next page) (Setting) Temp. alarm, CO2 density alarm, alarm delay 38 (Setting) Door alarm delay, ring back, remote alarm 38~40 (Setting) UV timer, power supply frequency 57~58 (Operate) Lighting UV lamp for 24 hours 59~60 78~79 (Setting) CO2 density of standard gas (Operate) Calibration of CO2 density by STD gas 79~80 → ■Tools#2 screen ♦Date & Time ♦Brightness/Sleep ♦DAQ Setting (Setting) Date, time (Setting) Brightness, sleep ON/OFF etc (Setting) Don’t push (Only for MTR-5000 user) 53 54~55 29 BASIC OPERATION ON LCD TOUCH PANEL *1: When an optional electric lock MCO-170EL is installed. *2: MCO-230AICUV or when an optional UV system set MCO-170UVS is installed. *3: When an optional STD gas auto calibration kit MCO-SG is installed.

Note: When an optional electric lock MCO-170EL is installed to the MCO-230AICUV/230AIC, an unlock key is provided in order to unlock the outer door during a power interruption or in case the electric lock fails. Always store this key in a safe place. It is recommended that you make a note of the key symbol and number in case the key is lost. WARNING Do not use the unlock key to unlock the outer door during H2O2 decontamination or during H2O2 gas resolve by UV. Doing so may cause harm to health from H2O2 gas leakage. 84 TROUBLESHOOTING If the incubator does not seem to be working properly, check the following items before calling for service. Symptom The incubator does not operate at all. Items to check and countermeasures Is the incubator plugged in? Is there a power outage, or has a circuit breaker interrupted the power? The removable power supply cord is connected to the port attached on the lower right side of the cabinet. An alarm is activated. [When starting operation] Does the chamber temperature match the set value? Does the CO2 gas density in the chamber match the set value? (1) Is the secondary pressure for the gas regulator at the specified value of 0.03 MPa(G)~0.1 MPa(G) (0.3 kgf/cm2(G)~1 kgf/cm2(G), 4.4 psi(G)~14.5 psi(G))? (2) Is the gas tube properly connected? [During operation] Is the high limit alarm temperature set at least 1 C higher than the chamber set temperature? Has the temperature setting been changed? Has the outer door been left open for a long time? Has a low-temperature object been placed in the chamber? If any of these is the case, the alarm will be automatically cleared if you wait. Has the gas tube come loose, or is there a gas leak? Has the CO2 gas density setting been changed? Is the gas cylinder empty? Check the primary pressure of the gas cylinder once a week. (When the primary pressure is 3.8 MPa(G) (38 kgf/cm2(G), 551 psi(G)) or lower, it is a sign that there is little gas remaining. Replace the cylinder soon.) Is the incubator operating beside the appliance that generates the electromagnetic wave? The chamber temperature does not match the set value. Is the ambient temperature less than 5 C different from the set value for the chamber temperature? Is the outer door closed with the inner door left open? Is the incubator operating beside the appliance that generates the electromagnetic wave? The chamber humidity does not rise. Is there enough water in the humidifying pan? (Be sure to use sterile distilled water.) The CO2 gas density does not match the set value. Is the secondary pressure for the gas regulator at the specified value of 0.03 MPa(G) ~0.1 MPa(G) (0.3 kgf/cm2(G)~1 kgf/cm2(G), 4.4 psi(G)~14.5 psi(G))? Is the gas tube blocked? Is the duct securely attached? Attach the duct properly to the 4 points hooks. (Fig. 1 on page 87) Is the fan attached properly? Confirm if the fan is pushed all the way to the motor shaft. (Fig. 2 on page 87) Is the incubator operating beside the appliance that generates the electromagnetic wave? A large quantity of CO2 gas is being consumed. Are the outer and inner doors being frequently opened and closed? Check whether gas is leaking from connectors due to deterioration of the gas tube, or whether there may be any pinhole leaks. The gas tube is a replaceable part, and it is recommended that it be replaced once a year. Is the packing seal for the inner door defective? Is the access hole open? 85 TROUBLESHOOTING Symptom Items to check and countermeasures Normal cultures are not possible, and the CO2 gas density is suspect. Is the ambient air environment around the incubator normal? Is there a source of polluted gas in the vicinity? CO2 gas is not being injected. The CO2 control method for the incubator is the ON-OFF method. CO2 gas is intermittently injected as the gas density in the chamber approaches the set value. Injections may be stopped for periods of approximately 15 seconds, but that is not an error. The gas is not injected until the temperature of the CO2 sensor becomes stable enough The CO2 gas density is slow to recover. approx. 1 hour, after turning ON the power switch or recovering from power failure. A HEPA filter is used for the incubator CO2 gas piping. If gas density is slow to recover when the CO2 gas pressure is normal, it is possible that the HEPA filter may be clogged. Contact our sales representative or agent. Is there little gas remaining in the CO2 gas cylinder? Is the secondary pressure for the gas regulator at the specified value of 0.03 MPa(G)~ 0.1 MPa(G) (0.3 kgf/cm2(G)~1 kgf/cm2(G), 4.4 psi(G)~14.5 psi(G))? Is the gas tube blocked? Is the duct securely attached? Attach the duct properly to the 4 points hooks. (Fig. 1) Is the fan attached properly? Confirm if the fan is pushed all the way to the motor shaft. (Fig. 2) UV lamp lights when the outer door is open. The outer door does not open. Does something push the door switch? When the optional MCO-170EL is installed: When the power switch is OFF, the electric lock is locked and the outer door does not open. Either turn ON the power switch or use the accessory unlock key to override the electric lock. During decontamination the outer door is electrically locked and does not open. 86 Symptom Items to check and countermeasures H2O2 decontamination cannot be performed. If the MCO-230AICUV is being used, are the optional MCO-HP, the optional MCO-170HB and the MCO-170EL installed? If the MCO-230AIC is being used, are the optional MCO-170UVS, the MCO-HP, the optional MCO-170HB and the MCO-170EL installed? Is the UV lamp burned out? If the UV lamp is burned out, H2O2 decontamination will not be possible. Is the H2O2 generator cable properly connected? Has the entire bottle of the H2O2 reagent been used? In H2O2 decontamination cycle, “Err34: H2O2 Volume” is activated. Is the duct securely attached? Attach the duct properly to the 4 points hooks. (Fig. 1) Is the fan attached properly? Confirm if the fan is pushed all the way to the motor shaft. (Fig. 2) Is the H2O2 generator securely installed? Set the 2 pins of the H2O2 generator in the 2 holes at the left bottom of the duct. (Fig. 3) Is it the end-of-life of the H2O2 generator? If the total operating time exceeds 5,000 hours, replace the H2O2 generator. 1.Position the center hole of the fan with the projection of the motor shaft. And insert it deeply. 2.Lightly turn the fan manually to make sure that it does not touch the rear panel. 3.Lightly pull the fan manually to make sure that it is installed. Fig. 1 Fig. 2 Fig. 3 Note: If the problem still has not been solved after trying the above checks and countermeasures, or for any problems not covered here, contact our sales representative or agent.
