UV LAMP (OPTION)
When the optional UV System MCO-170UVS is installed on the model MCO-50ML, the UV lamp lights for
preset amount of time after closing the outer door to disinfect the water in the humidifying pan and the air
circulating in the chamber.
Using UV lamp
1. Set all inner attachments in the chamber properly, and place the cultivation samples on the trays.
Note:
Improper setting of the inner attachments adversely affects the chamber temperature distribution and
humidity recovery performance.
2. Close the outer door. The UV lamp will light for the preset amount of time (i.e. the time set on “UV
Lighting Time” plus the time added by “UV Extended Time”). Refer to pages 71 and 73 for instructions.
Notes:
• If you open the outer door while the UV lamp is ON, the lamp will be turned OFF. When you close the
door again, the lamp will light for the preset amount of time.
• Repeated opening and closing of the outer door may adversely affect the condensation in the chamber and
the chamber temperature distribution because the UV lamp generates heat for a long time. It may also
shorten the service life of the UV lamp.
• UV lamp ON period can be changed (refer to page 71).
• UV light is harmful to the eyes. Do not turn the UV lamp ON when the inner door is open.
3. If the outer door is not opened for at least 12 consecutive hours, then the UV lamp lights every 12 hours for
the preset amount of time.
Note:
Opening the outer door will reset the 12-hour period.
The recommended replacement time for the UV lamp (i.e., when the UV output ratio drops to
60 %–70 % of its initial value) is when the accumulated ON time reaches 5,000 hours. The message
“Warning: UV Bulb Life” then appears in the message display area. Replace the UV lamp promptly at this
point. Contact our sales representative or agent for replacement.
If the UV lamp burns out, “Err18: UV Lamp Abnormal” is displayed in the message display area. Replace
the UV lamp, and replace the glow starter (type FG-7P or FG-7PL) at the same time. Contact our sales
representative or agent for replacement.
