UV LED Head enclosure.
Warning:
Use UV radiation eye and skin protection during servicing if access to the UV LED modules is
required during operation.
Risk Group 3 (IEC62471)
WARNING: UV emitted from this product. Avoid eye and skin exposure to unshielded product.
CAUTION: Possibly hazardous optical radiation emitted from this product. Do not stare into operating lamp.
CAUTION UV:
Hazardous visible radiation is emitted from this product. Eye or skin irritation may result from
exposure. Use appropriate shielding.
Ensure main power supply is disconnected prior to making any changes to cabling configurations.
Operate the unit in a well-ventilated area with at least 5 inches (12cm) clearance on both sides of the system
power supply unit for proper air flow. Ensure that both intake and exhaust vents located on the LED heads
have at least 5inches (12cm) of clearance to allow sufficient air flow.
Avoid physical shocks or jarring of the LED Head, especially while the unit is operating.
When necessary, clean the optical window of the UV LED Head using an optical cleaning solution. Refer to
Section
9.3
, “Cleaning the LED Head”.
The outer lens frame of the UV LED Head includes an optical window assembly. Improper handling and
cleaning practices can damage polished surfaces or coatings which are utilized in this optical window. Note
that damage to the surface of the glass or coating can degrade the unit’s performance. Proper handling and
cleaning technique is very important. Below are the recommended procedures for cleaning of the OmniCure®
UV LED Head optical window.
Always handle the UV LED Head by the metal enclosure; never touch the optical window with your fingertips.
The moisture or oils on your fingertips can damage the coating of the lens window. Fingerprints left on an
optical surface for an extended period of time, can become a permanent stain. Even if you are wearing gloves,
avoid touching the optical surface.
Never handle the optical window with metal implements or tweezers.
Do not place the UV LED heads lens assembly onto a hard table-top surface; this can cause scratches in the
window surface.
To store UV LED heads, wrap them individually in a clean, lint free bag and store in a safe place.
Never store unwrapped LED Heads together in a box or bag, as they may become damaged if they come in
contact with each other.

Cleaning Materials
Lint-free lens tissue, lint-free cotton swabs, lint or powder-free gloves or finger cots.
An organic solvent, such as reagent-grade isopropyl alcohol, reagent-grade acetone, or lens cleaning
solution.
