PRECAUTIONS FOR SAFE OPERATION CAUTION This unit must be plugged into a dedicated circuit protected by branch circuit breaker. Use a dedicated power source as indicated on the rating label attached to the unit. A multiple-tap may cause fire resulting from abnormal heating. Never store corrosive substances such as acid or alkali in this unit if the container cannot be sealed.
LABELS ON INCUBATOR Warning and caution labels are attached to the incubator. The following table describes the labels.

INSTALLATION SITE For correct operation of the incubator, install it in a location with the following conditions. WARNING When using CO gas for control, make sure that there is adequate ventilation. Using CO gas in a small room without adequate ventilation may cause gas poisoning or oxygen deprivation. In addition, when opening the incubator doors, do not directly inhale the air in the chamber.
INSTALLATION 1. Remove the packing tape and clean up. Remove all the tape that is securing the doors and the inner attachments. Open the doors for ventilation. If the outer panels are dirty, dampen a cloth with a diluted neutral detergent and wipe them. (Using an undiluted solution may damage the plastic.
Connecting a CO 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 escape. 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 escaping gas.
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.
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 CO gas density. Do not place harmful materials in the chamber. Never place samples that release acidic, alkali, or corrosive gas in the chamber.
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.
REMOVING INNER ATTACHMENTS CAUTION Wear rubber gloves when performing maintenance on the chamber. Failure to wear gloves may result in cuts or abrasions from sharp edges or corners. Be careful not to damage the water level sensor or the UV lamp in the rear duct. (When an optional UV system set MCO-19UVS is installed.) Do not use detergents or antiseptic solutions with acid, alkali, or chlorine.
Page 22
REMOVING INNER ATTACHMENTS 8. Lift the rear duct and remove it from the pins at the rear side. (Fig. 7) 9. Remove the fan by pulling out the central spring and then by pulling out the fan. (Fig. 8) 10. Remove the silicon caps of the access port, one each from interior (Fig. 9) and exterior (Fig. 10). Rear duct 1.
INSTALLING INNER ATTACHMENTS Use the following steps to install the inner attachments properly. 1. To reinstall all the attachments, perform the procedure in reverse order from step 10 on page 20. 2. When installing the fan, insert it to the motor shaft securely. Lightly turn the fan manually to make sure that it does not touch the rear panel.
FILLING HUMIDIFYING PAN Use the following procedure to fill the humidifying pan or to replace the water. 1. Lift the front side of the humidifying pan cover. (Fig. 1) 2. Pull out the humidifying pan toward you. (Fig. 2) 3. Dispose of the remaining water in the humidifying pan and clean the humidifying pan with a diluted detergent.
WATER LEVEL SENSOR This incubator is equipped with a water level sensor. The water level sensor is set automatically when the humidifying pan is installed. Take care not to damage the water level sensor when removing or installing the humidifying pan. When the humidifying pan is removed (side view) Water level sensor Humidifying pan...
ROUTINE MAINTENANCE To use this unit in a clean condition, clean the chamber and all the inner attachments at least once a month. 1. Remove all the inner attachments by the procedures shown on page 19. 2. Clean the chamber and all the inner attachments by the procedures shown on page 18. 3.
SETTING OF CHAMBER TEMPERATURE AND CO DENSITY Table below shows the basic procedure for setting the chamber temperature and CO density. The high 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 36.5 C and CO density is 5 %.
SETTING OF ALARM RESUME TIME The alarm buzzer is silenced by pressing the alarm buzzer stop key (BUZZER) on the control panel during alarm condition. (The remote alarm is not canceled.) The buzzer will be activated again after certain suspension if the alarm condition is continued. The suspension time can be set by following the procedure shown in the table below.
KEY LOCK FUNCTION This unit is provided with the key lock function. When the key lock is ON, change of temperature, CO density setting through the key pad is not available. Note: The key lock is set in OFF mode at the factory. Display Mode Function...
AUTOMATIC CO CYLINDER CHANGEOVER A gas auto changer MCO-5GC is available as an optional accessory. This system switches the CO supply line when one CO gas cylinder becomes empty. Note: The installation of MCO-5GC should be implemented by a qualified service personnel. Install the MCO-5GC and then perform the following procedure 1.
Page 31
The MCO-5GC detects that there is no more CO gas in a CO gas cylinder when the CO density in the chamber does not increase for a while even after opening the CO gas valve in the incubator. The CO supply line may also be switched for other reasons even though there is CO gas left in the CO cylinder: blocking or restricting of gas tube, reduction of CO...
UV LAMP The clauses below are applicable when an optional UV system set MCO-19UVS is installed. A UV lamp is located inside the rear duct to sterilize the water in the humidifying pan and air circulating in the chamber. • The UV light is exposed only to the inside of the rear duct and the humidifying pan cover when all chamber components are installed properly.
Precautions when using the UV lamp The cautions below are applicable when an optional UV system set MCO-19UVS is installed. ● Always use humidifying pan and humidifying pan cover The humidifying pan and humidifying pan cover prevent the UV light from escaping. Make sure they are installed even if you do not need humidity.
UV LAMP Change of setting for UV lamp ON period The cautions below are applicable when an optional UV system set MCO-19UVS is installed. Follow the procedure below when changing the setting for UV lamp ON period.
