decon board MCO-170HB, and electric lock MCO-170EL are all
installed on the model MCO-230AICUVL.
• UV system set MCO-170UVS, H

Read the precautions for safe operation on pages 5–9 before performing decontamination.
Notes:
• Never start H

decontamination when “Warning: UV Bulb Life” is displayed in the message display field.
The UV resolution will be insufficient.
• If the power supply is cut off during H

decontamination, the electric lock will remain ON. After the
power supply is restored, the H

gas resolution process will restart and finish automatically. In this case,
repeat the decontamination process because the decontamination will not be complete.
