6. Maintenance
6.1 Checkup
Perform checkup and maintenance by taking the following recommended intervals as an indication:
■ Be sure to perform regular checkup of the equipment and components.
Verifying LEDs being lit
Verifying state of the turntable
Daily checkup
Checking the lens cover for
contamination
Whether the connections are sound
Checking the step mode switch for
Weekly checkup
contamination
Checking inside the curing chamber
for contamination
Replacing the lens cover
(Replacement interval as an
Parts replacement
indication: 1 year *depends on
frequency of usage)
■ Be sure to clean the curing chamber regularly, as otherwise, the contaminated chamber could not exercise
suffi cient curing performance. If fl ammable disinfectant is used (e.g. Isopropyl alcohol based), there is risk
of ignition/explosion if lamp is started with vapors in the chamber.
● In case a LED unit fails, other LED units can still properly irradiate light. However, as the total amount of
light is reduced, the curing time should be extended and curing status should be suffi ciently monitored.
The failed LED unit should be promptly repaired.
6.2 Cleaning and Replacement of parts
Be sure to plug off the power cord so that the unit is not activated during cleaning or replacement work.
■ Maintenance, if intended after a prolonged use, should be conducted after the unit temperature suffi ciently
lowers.
