4. Install and uninstall way
4.1 Connect the LED power supply line with the power
(24V~) of dental unit. Tight the nylon thread to the
fixation of the dental unit, then it will be available for
operation.
Notice: When installing the LED, be sure the power
is cut o. The two power wires should be a little longer
than the nylon thread to keep the power wire safe.
4.2 Take o the red cap from the optical ber and insert
the metal part into the front of the built-in LED.Q (Make
sure to screw the ber to the end by rotating it).
4.3 Install the light hood as shown in picture 1.
5. Operation
5.1 Press the button to turn on the device.

5
5.2 After turning on the device, keep pressing the button
in 1second, then the indicator light scroll shines. Now you
can choose 10s, 20s, and 30sworking time.
5.3 While operating, put the light source alignment the
position where needs to be solid, press the button in a
short time, then with a “Di” voice, the main unit shines
blue light and starts the countdown. When countdown
back to 0, the main unit stops working, and with a long
“Di” voice, the indicator light comes back to the setting
time.
5.4 It can be stopped working at any time by short
pressing the button while operating.
5.5 At the end of a working cycle, the next working cycle
can be started immediately by short pressing the button. If
the main unit gets hot obviously, please turn o the device
until the main unit becomes cool.
Please don’t make it continuously illuminate more than
10times.
5.6 If there is resin on the ber after using, please clear it
by cotton cloth to make sure the power intensity is good.
5.7 The device will turn o after 2 minutes idle.
5.8 This device can cure composite resin not less than
4mm in 10 seconds.

6. Cleaning, Disinfection and Sterilization
The cleaning, disinfection and sterilization of optical ber
is as follow.
Unless otherwise stated, they will be hereinafter referred
to as “products”.
Warnings
The use of strong detergent and disinfectant (alkaline
pH>9 or acid pH <5) will reduce the life span of
products. And in such cases, the manufacturer takes no
responsibility.
This device shall not be exposed to high temperature
above 138℃.
Processing limit
The pro ducts have been designed for a large number of
sterilization cycles.
The materials used in manufacture were selected
accordingly. However with every renewed preparation for
use, thermal and chemical stresses will result in ageing of
the products. The maximum number of sterilizations for
optical ber is 500 times.
6.1 Initial processing
6.1.1 Processing principles
It is only possible to carry out eective sterilization after
the completion of effective cleaning and disinfection.
Please ensure that, as part of your responsibility for the
sterility of products during use, only suciently validated
equipment and product-specific procedures are used

7
for cleaning/disinfection and sterilization, and that the
validated parameters are adhered to during every cycle.
Please also observe the applicable legal requirements in
your country as well as the hygiene regulations of the
hospital or clinic,especially with regard to the additional
requirements for the inactivation of prions.
6.1.2 Post-operative treatment
The post-operative treatment must be carried out
immediately, no later than 30 minutes after the completion
of the operation. The steps are as follows:
1. Remove the optical fiber from the Curing light
Device,and rinse away the dirt on the surface of product
with pure water (or distilled water/deionized water);
2. Dry the product with a clean, soft cloth and place it in a
clean tray.
Notes
a) The water used here must be pure water, distilled water
or deionized water.
6.2 Preparation before cleaning
Steps
Tools: tray, soft brush, clean and dry soft cloth Remove
optical ber from main unit and put it into the clean tray.
Use a clean soft brush to carefully brush the optical ber
until the dirt on surface is not visible. Then use soft cloth
to dry the optical fiber and put them into a clean tray.
The cleaning agent can be pure water, distilled water or
deionized water.

6.3 Cleaning
The cleaning should be performed no later than 24 hours
after the operation.
The cleaning can be divided into automated cleaning
and manual cleaning. Automated cleaning is preferred if
conditions permit.
6.3.1 Automated cleaning
•The cleaner is proved to be valid by CE certificationin
accordance with ENISO 15883.
▪There should be a flushing connector connected to the
inner cavity of the product.
▪The cleaning procedure is suitable for the product, and
the irrigating period is sucient.
It is recommended to use a washer-disinfector in
accordance with EN ISO15883. For the specific
procedure, please refer to the automated disinfection
section in the next section “Disinfection”.
Notes
a) The cleaning agent does not have to be pure water. It
can be distilled water, deionized water or multi-enzyme.
But please ensure that the selected cleaning agent is
compatible with the product.
b) In washing stage, the water temperature should not
exceed 45 °C, otherwise the protein will solidify and it
would be dicult to remove.
c) After cleaning, the chemical residue should be less than
10mg / L.
