5. System Maintenance and Cleaning
5.1 Maintenance
Disconnect power cord before cleaning, since there is still a risk of electrical shock. The inner
surface of the chamber is surrounded by glossy stainless steel to reflect the LED light. To maintain
the light curing efficiency, please make sure the stainless steel is cleaned before curing.
5.2 Cleaning
Please use neutral detergent for cleaning outer surface and chamber. Do not touch LED,
as hand sweat considerably shortens the life cycle of the LED. The time for these
maintenance/cleaning procedures depends on the frequency of use and the working habits of the
users. It is recommended to clean chamber and stainless steel reflector throughout every 2
weeks at least.
5.3 Changing LED
Total 12 LEDs are used in this unit. To replace the LED, please refer to the Service Manual. All LED
parts can be purchased from authorized PrintIn3D DigiTech distributors.
5.4 Calibration
In order to ensure optimum performance, it is recommended to calibrate LED intensity every year.
Please send the unit to authorized PrintIn3D DigiTech distributor for calibration.
