INSTALLATION

Note: - Upon receiving the QHL75® Curing Light, check the packaging and parts for any possible damage that may have occurred in transit. If damage is apparent, please contact your dealer immediately.

- Verify the line plug of the power cord is properly rated, that all connections have been performed to safe practices and all local regulation requirements (always use the light in conjunction with a properly grounded outlet). - Affix the eye protection shield to the probe chuck on the nosecone of the hand-piece or use suitable protective eye wear.

1.

Insert the desired fiberoptic probe into the nozzle of the handpiece until it snap-locks in place.

2.

Insert the holster in mounting hole on top of the base/power unit (forks positioned forward) and place the handpiece in holster with the fiberoptic probe/nosecone facing the rear of unit.

3.

Plug the detachable power cord into receptacle on the side of the base/power unit. The power cord may now be plugged into the AC supply.

4.

Refer to the CLEANING section for specific asepsis/disinfecting instructions.

OPERATION

The main power switch is located on the side of the base/power unit. The switch illuminates (green) when pressed to the “on” - “I” position (Models 502 - 506) indicating the unit is receiving power and is ready for curing. The main power is now controlled by the activation (trigger) switch on the handpiece. Momentarily depress the trigger switch on the front of the handle to activate the lamp and begin the exposure cycle. The unit will beep every 10 seconds during the exposure. The QHL75® Curing Light will automatically shut OFF after 1 minute of exposure time. The unit can be activated again by momentarily depressing the on/off trigger switch on the front of the handle. The exposure cycle can be interrupted at any time by depressing the trigger switch once again. The high speed cooling fan will start at the beginning of each exposure. After the final exposure, the fan will continue to run for approximately five to six minutes before automatically shutting off. Note: Do not turn off main power or unplug the unit until the fan has finished this cycle. The QHL75® Curing Light is protected from over-heating by thermal safety devices. Should the unit overheat, it will automatically turn off until normal operating temperatures are reached. When the curing operation is complete, return the handpiece to the handle holster. During prolonged periods of non-use, the unit may be turned off by depressing the main power switch to the “off” - “O” position, switch illumination will also turn off (Models 502-506). 3

CURING: •

For optimal curing, always refer to our composite manufacturer’s exposure time recommendations.

•

Fiberoptic Light Probes: The QHL75® Curing Light comes with one 8mm, 60º probe. Additional probes may be ordered separately (Figure 5). All light probes rotate 360º within the probe chuck.

•

Check and measure the light output intensity daily using a light intensity radiometer to verify lamp, filter, probe performance and to ensure proper curing of resin materials. The CureRite™ by DENTSPLY is an excellent radiometer. Attention: Frequently verify the light output intensity (using the standard 8mm fiberoptic probe) on a CureRite™ radiomenter to ensure sufficient curing power.

CONTRAINDICATIONS 1

Persons who have a medical history indicating photobiologic reactions (including persons with solar urticaria or erythropoietic protoporphyria) or who are using photosensitizing drugs (including 8-methoxypsoralen or tetracycline) should not be exposed to light from the lamp.

2.

In cases where a patient or user of the QHL75® Curing Light has been fitted with an implanted heart pacemaker and has been cautioned against the use of small electrical appliances (such as electric shavers, hair dryers, etc.) we recommend that the QHL75® Curing Light not be used.

WARNING 1.

When curing the material, position the light over the polymerizable material and avoid extraneous contact with soft tissue whenever possible. Prolonged continuous exposure to soft tissue can result in injury or irritation.

2.

Allow the QHL75® Curing Light maximum time to cool prior to removing the nosecone, exposing potentially hot metal lamp reflector cups.

SAFETY PRECAUTIONS 1.

Never activate lamp when the fiberoptic probe has been removed from handpiece.

3.

A filter is located within the handpiece to allow transmission of only useful curing irradiation. The filter should be examined before use for any cracks or defects.

2.

Do NOT look directly at the light emitted from the tip of the instrument. As with any bright light source, staring directly at the source may cause temporary effects such as after-image.

A CRACKED OR MISSING FILTER MUST BE REPLACED BEFORE USE TO PREVENT THE EMISSION OF HARMFUL IRRADIATION. 4. 5. 6.

7. 8.

9.

Persons with known retinal disease should be careful and should employ suitable protective measures after consultation with their ophthalmologist.

Persons who have had surgery for eye cataracts are especially sensitive to light and generally should not use the QHL75® Curing Light unless they employ suitable protective measures which should include the use of spectacles which filter out blue-violet and ultraviolet light. When a lamp has burned out wait until the lamp is cool before attempting to replace it.

Fiberoptic tips must be maintained in a clean condition. Contaminating the tip will reduce the effectiveness of the light transmitted.

Other lamps may appear similar but perform differently. Replace only with genuine QHL75® Curing Light replacement bulbs. DO NOT IMMERSE UNIT IN WATER. See “Cleaning Instructions”. 4

CLEANING

The fiberoptic light probe may be autoclaved or dry heat sterilized (see manufacturer’s instructions). Any cured resin materials on the tip of the light probes should be removed (pried off) with a razor blade or sharp knife to ensure proper curing of composite materials. NOTE:

Always protect open ends of the light probes from abrasive materials. Should polished ends become marred, light transmission and curing will be diminished. Disconnect the power cord from the base unit prior to cleaning. Do not use a glutaraldahyde based solution to disinfect your unit. This could affect the mechanical operation and damage the plastic housing.

Clean and disinfect the surfaces of the unit housings by applying an approved non-immersion type disinfectant solution* carefully following the instructions provided by the disinfectant solution manufacturer. *NOTE: Water based disinfectant solutions are preferred. Alcohol-based disinfectant solutions may be harmful and may discolor plastic materials. Perform the disinfectant procedure only after the unit has cooled to room temperature. Wipe the unit with a damp cloth to remove any residual deposits of the disinfectant solution. Use of alcohol-based disinfectant solutions will void the warranty.

Remember to reconnect the power cord to the unit when cleaning process is completed.

LAMP REPLACEMENT The lamp used in the QHL75® Curing Light is a 75 watt, 11.0 volt quartz halogen type, which has an estimated life rating of 100 hours under normal usage and with nominal input voltages (increased or decreased AC input voltage may reduce life). Bulb life may be shortened by a sharp blow during use or cool down period. As the light intensity of all bulbs decreases during usage, we recommend to check the light output frequently using a CureRite™. Replacement is recommended when lamp transmission is below the minimum specified by composite manufacturers or less than a 300mW/cm2 radiometer reading. Disconnect the power cord from the unit and be sure the lamp has cooled before replacing.

Proceed by turning the nosecone to align the line with the open circle on the body of the handpiece. Pull the nose cone off to expose the light bulb. Gently wiggle the lamp out of the socket and replace with a new lamp. A bulb extraction tool is provided should you have difficulty removing the bulb. Good practice is to inspect the optical filter within the nose cone. Remove any contaminants using a cotton swab. A cracked, peeling, discolored or defective filter should be replaced.

When inserting the new lamp, it is recommended that you use a tissue to hold the lamp and prevent skin acids from etching the quartz envelope which will lead to premature lamp failure. Replace the nose cone and turn so the line is opposite the closed circle on the handpiece

FUSE REPLACEMENT

NOTE: 1. 2.

3. 4.

Always disconnect the power cord from the unit before replacing the fuses (use fuses with the same ratings).

The fuses are located in the fuse compartment of the AC receptacle, at the side of the base unit. With a small screwdriver, pull out the fuse compartment and let the door fall open (on its pivot) to expose the fuses. Pull out the fuses, visually inspect the fuses and replace if necessary with fuses of the same ratings. Lift the fuse door open until it covers the fuses and push the fuse compartment completely in the AC receptacle until it locks in place. Remember to reconnect the power cord. 5
