INSTALLATION Installation site To operate this unit properly and to obtain maximum performance, install the unit in a location with the following conditions: Note: The ambient temperature must be at least 5 C lower than the set temperature. 1. A location not subjected to direct sunlight or direct air flow from an air conditioner 2.
INSTALLATION Prevent contamination To prevent contamination of the chamber, select an appropriate location for installation as well as ensuring the complete disinfection of the chamber components. 1. 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 the normal environment.
BEFORE COMMENCING OPERATION Sterilizing of chamber and attachments Before first start-up of the unit, the chamber and internal attachments should be cleaned and sterilized as follows. Note: Take care not to damage the water level sensor or UV lamp (option) at the time of removal or replacement of attachments.
BEFORE COMMENCING OPERATION Connection of N (or O ) 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.
BEFORE COMMENCING OPERATION Connection of gas injection nozzle In the case of control of O density in the chamber, connect the gas injection nozzle to the gas injection port by using the connecting pipe enclosed (inner diameter; 5mm, outer diameter; 9mm, length; 300mm). This helps faster recovery of humidity after opening of the inner door.
BEFORE COMMENCING OPERATION Connection of CO 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.
OPERATING INSTRUCTIONS Operation of keys on the control panel Table below shows the basic procedure for setting the chamber temperature, CO and O density. The upper limit alarm temperature setting is also shown in the table. Perform key operations in the sequence indicated in the table.
OFF means the accumulated time has exceeded about 1,000 hours and recommends the replacement of the lamp. When replacing the UV lamp, contact Sanyo sales representative or agent. • E18 is displayed on the temperature indicator when the UV lamp is burned out. In this case, replace the lamp immediately.
5 minutes or if only the outer door is opened repeatedly. • For the replacement of UV lamp, contact Sanyo sales representative or agent. Pressing CAL key for about 5 seconds leads the calibration mode.
OPERATING INSTRUCTIONS Automatic gas cylinder changeover This incubator is provided with an automatic cylinder changeover system, which switches the gas (N ) cylinder when one gas cylinder becomes empty. Also, an automatic CO cylinder changeover system (MCO-5GC) is available as an optional accessory. This kit switches the gas supply line when one CO gas cylinder becomes empty.
