Cautions For Usage - Sanyo MCO-18AIC Service Manual

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
Ventilate a room air occasionally when using CO gas for control. The gas density will increase in an
2
enclosed small room and high level of gas density can be hazardous to health. In addition, avoid
inhaling the chamber air directly when opening the door if CO gas is used.

4. Install in an appropriate environment
With an automatic calibration function, the CO sensor is calibrated by utilizing air from the local
2
environment. Place the unit in an environment which will reflect normal atmospheric conditions.

5. Setting of 5 C higher than the ambient temperature
o
The chamber temperature must be at least 5 C higher than the ambient temperature. For example, the
o o
chamber temperature is set to 37 C, the ambient temperature must be less than 32 C. 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.
6. 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 26 "Routine maintenance" for details.
7. 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.
8. 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.
9. 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-18UVS is installed).
