Cleaning/Disinfecting/Sterilizing - KERR OPTILUX 501 Manuel D'utilisation

a) LAMP -The inner glass envelope (bulb) must be clear and the coiled
filament should be visible. The lamp reflector surface (mirror) must be
clean - refer to section d below. Replace the lamp (part no. 21237) if the
following conditions are present: Severe blackening or frosting of the
envelope; peeling or damaged reflector coating; cracked reflector,
burned contact blades or pins. If contact blades or pins are burned,
return entire unit to authorized service center for repair of lamp socket.
Refer to section 3 for lamp replacement instructions.
Important - To prolong lamp life, allow the fan to complete its automatic
cooling cycle. Once the fan has turned off, the unit may also be switched
off.
b) FILTERS -Remove the front of the plastic handpiece containing the
filters and hold it up to a low power light source such as a desk lamp.
Look through the filters. The optical filters must be clean and highly
reflective - refer to section d below. Replace the plastic front handpiece
and filter assembly (part no. 952212) if the following conditions are
present: Missing filters; blistered or peeling filter coatings; cracked
filters.
c) FIBER OPTIC LIGHT GUIDE - Remove the fiber optic light guide and
hold one end near a low power light source such as a desk lamp. The
fibers must transmit light and appear translucent (clear). The surface of
the fibers should have the appearance of polished glass. Replace the
fiber optic light guides (part no. 20898 and 952213) if the following
conditions are present: broken fibers (internal black spots or darkened
areas); severely chipped or etched fiber ends. Brown or gray deposits
on the ends of the fiber optic light guide can be removed using the
Optics Maintenance Kit described in section d below. The black silicone
rubber that covers the curved portion of certain light guides is for
cosmetic and protective purposes.
silicone rubber will not reduce light transmission.
To help maintain fiber optic light guide performance, it is recommended
that the tip of the light guide not touch the restorative material within the
first few seconds of curing. Subsequently, the tip may be placed in
contact with the material. The purpose of this technique is to prevent the
composite material from adhering to the tip. Once the outer layer of the
composite is set, no adhesion occurs.
accidentally, no damage is done.
rubbed off after soaking the tip in alcohol.

d) OPTICS MAINTENANCE KIT, PART NO. 21042 - This kit contains
materials for cleaning lamp reflector and optical filters, displayed in
Figure 14. It also includes specially formulated low speed polishing
disks to remove deposits that form on the glass surface of the fiber optic
light guide during autoclaving, as shown in Figure 15. After numerous
autoclave cycles, a brown or gray discoloration can accumulate on the
polished ends of the light guide. This is a residue (commonly called
boiler scale) that forms during the autoclave drying cycle.
The deposit is usually brown or gray in color due to contamination of the
autoclave water by corrosion and ionization of metal instruments, dirty
handpieces, etc. To minimize the formation of deposits, be sure that the
autoclave water is clean (replaced frequently) and, if possible, autoclave
fiber optic light guides separate from handpieces and other instruments.
Kerr recommends that fiber optic light guides be polished every 50
autoclave cycles. Following the instructions included in the kit helps
promote optimum curing performance.

11. CLEANING/DISINFECTING/STERILIZING

CAUTION: Before cleaning, disinfecting, or sterilizing turn
a)
master power switch S1 "OFF" (O) and disconnect curing light unit
from AC outlet (Mains)!
b) FIBER OPTIC LIGHT
INSTRUCTIONS:
The glass fiber optic light guide is a patient contact part and must be
cleaned and sterilized before each patient application. This is easily
done, since the light guide is completely removable and autoclavable.
CLEANING: Fiber optic light guides should be cleaned as follows:
1. Immerse/thoroughly drench fiber optic light guide in a surface
decontaminate cleaner (soap and water cleaning solution) at room
temperature 69°F (20°C).
2. After at least 10 minutes, scrub with an instrument cleaning brush
until visibly free from debris.
3. Rinse all parts with warm tap water.
