UV LAMP
The clauses below are applicable when an optional UV system set MCO-19UVS is installed.
A UV lamp is located inside the rear duct to sterilize the water in the humidifying pan and air circulating in
the chamber.
Following shows precautions and instructions about the UV lamp.
• The UV light is exposed only to the inside of the rear duct and the humidifying pan cover when all
chamber components are installed properly.
• During cultivation, ensure all components are located adequately and never turn on the UV light without
the humidifying pan cover.
• Even if the unit is operating without turning on the UV lamp, the humidifying pan cover should be
installed properly. An operation without humidifying pan cover will affect the temperature distribution and
humidify recovery.
• When checking the UV lamp operation, open the outer door and push the door switch with the inner
door closed. The visible blue light can be checked under the humidifying pan cover. The UV light is
harmful to eyes. Never turn on the UV light with the inner door or humidifying pan cover opened.
• The UV lamp is ON for a predetermined period after the outer door is closed, or every 12 hours when
the outer door is not opened more than 12 hours continuously. The period of factory setting is 5 minutes.
The period can be changed when necessary as shown in the page 34.
• The recommended timing of lamp replacement (the ratio of UV output is less than 70% of initial value) is
when the accumulated ON time is over about 1,000 hours. The blink of the UV indicator when the UV
lamp is OFF means the accumulated time has exceeded about 1,000 hours and recommends the
replacement of the lamp. When replacing the UV lamp, contact our sales representative or agent.
• E18 is displayed on the digital temperature indicator when the UV lamp is burned out. In this case,
replace the UV lamp immediately. At the time of replacement, also replace the glow starter (Type;
FG-7P). For the replacement of UV lamp and glow starter, contact our sales representative or agent.
