CAUTIONS FOR USAGE

1. Install on a sturdy and level floor

Install the unit on a sturdy and level floor and take precaution for preventing tipping over. Inadequate installation may result in water leakage or injury from the unit falling or tipping over.

2. Install in a place not subject to direct sunlight and far from heat sources

Never install the unit outdoor, near windows, or in direct sunlight. And install the unit far from heat sources such as exhausted heat from other equipment. The installation in improper location may result in insufficient performance.

3. Ventilate a room air

4. Setting of 5oC higher than the ambient temperature

The chamber temperature must be at least 5oC higher than the ambient temperature. For example, the chamber temperature is set to 37oC, the ambient temperature must be less than 32oC. Ensure the ambient temperature is within the desired range.

Also, do not place the unit in the direct air flow from an air conditioning system. Cool air from an air conditioning system may cause condensation and lead to possible contamination.

5. 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.

6. Fill the humidifying pan with sterile distilled water

Always use sterile distilled water to fill the pan. The RH PAN lamp on the control panel flashes when the water level is low. Refill the sterile distilled water to the pan when the RH PAN lamp blinks. Note that when low temperature water is poured, the chamber temperature drops significantly. Clean the pan once a month.

7. 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 unit will fail to exhibit its maximum performance.

8. 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 (when an optional UV system kit MCO-18UVS2 is installed).

CAUTIONS FOR USAGE

9. Use clean containers

The Petri dishes or bottles for culturing may cause contamination in the chamber. Clean the containers before storing them in the chamber.

10. 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.

11. 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.

12. Alarm

Always investigate the cause and fix the alarm condition immediately when the alarm is activated. Refer to page 25 for alarm details.

13. Do not use CAL key

Do not use CAL key on the control panel in normal use. Pressing this key leads the calibration mode. Wrong key operation affects the basic performance. Never touch any other keys on the control panel in the event of pressing CAL key accidentally. After about 90 seconds, the unit returns to chamber temperature display mode automatically.

14. If not used

When the unit is not used, dispose of the water in the humidifying pan and completely remove any moisture in the chamber completely. Check that the chamber is completely dry before closing the doors.

15.Thermal conductivity CO2 sensor

It is not abnormal that the thermal conductivity CO2 sensor displays CO2 density higher than the actual density when the chamber humidity temporarily goes down. And take care of the level of humidifying water because the lack of water affects the CO2 density.
